This is normal and correct.
The meta data (permissions, ownership, mtime etc) are stored in a
seperate file (the attrib file, one per directory). It can't be
stored with the file (as on the client) because of pooling, and also
some meta data values (eg: owned by root, or a block or character
special file) can't be created unless you are root.
For security reasons files are stored using $Conf{UmaskMode},
which by default disables world read/write permissions.
If you browse the directory using the web interface you should
see the right permissions.
As Les points out, you need to use the -p and --numeric-owner
options with tar when you restore files (extracting). That
doesn't apply to when you are doing a backup (creating an
archive of the client).
I'm just investigating a difference in TarClientCmd that I'm not sure if that
could cause it
Default:
$Conf{TarClientCmd} = '$sshPath -q -x -n -l root $host env LC_ALL=C $tarPath
-c -v -f - -C $share Name+ --totals';
Overridden:
$Conf{TarClientCmd} = '$sshPath -q -x -n -l root $host $tarPath -c -v -f - -C
$shareName+ --totals';
Removing the env LC_ALL=C should be ok so long as your client has
a locale of C.

First, the 'c' should be 'C$' - it should match the share name.
Also, you can't use wildcards in $Conf{BackupFilesOnly}. You
need to use an absolute path.
#FILES TO EXCLUDE
#-
$Conf{BackupFilesExclude} = {
'c' = ['/Program Files/*', '/WINDOWS/*'],
'c' = ['/Documents and Settings/*'],
};
Once again the 'c' should be 'C$'.
Unfortunately smbclient doesn't allow you to use both
$Conf{BackupFilesOnly} and $Conf{BackupFilesExclude}. One choice
is to change the share to be just the directory tree you want to
back up and leave $Conf{BackupFilesOnly} empty.
Using wildcards in $Conf{BackupFilesExclude} with smbclient is ok,
but you need to use '\' instead of '/':
$Conf{BackupFilesExclude} = {
'C$' = ['\\Program Files\\*', '\\WINDOWS\\*'],
'C$' = ['\\Documents and Settings\\*'],
};
(If you are entering this via the CGI interface you only need
to enter a single '\'.)

Holger writes: two things are really confusing me: 1.) The title claims that it is supposed to be an *rsync* xfer, the error message clearly indicates that *ftp* is attempted (and fails). Tim, could you please clarify which transfer method you are trying to use? The code loads all the Xfer modules and the failure happens when there is a module that isn't found. The Xfer method doesn't matter at that point. Looks like you need to install the File::Listing module. Paul - the code should check for this and it should be in the docs too. Isn't the same true for Archive::Zip and XML::RSS? I'm not sure those two *can* be handled in a sane way, but I'll have a look in the next few days and try to provide a patch. Yes, like other non-builtin modules, the ftp code should load this module inside an eval() in the BEGIN block, and set a flag if it fails. In particular, this line: use File::Listing qw/parse_dir/; in lib/BackupPC/Xfer/Ftp.pm should be moved inside the BEGIN block and used with an eval. It's not quite as simple as adding File::Listing to this list: my @FTPLibs = qw( Net::FTP Net::FTP::RetrHandle ); since it needs the qw/parse_dir/.

Re: [BackupPC-users] Next release
Obj writes:
I am running version 3.2.0. can someone tell me why
$Conf{BackupFilesExclude} is not working. It still backups up all Temp
folders, and .mp3 files, etc. The backup method is SMB.
You sent me offlist your config file and XferLOG file. Thanks.
The problem is that if you use wildcards (in particular *) in
excludes, smbclient will only do the right thing if you use the
Windows-style directory separator '\' instead of '/'.
Therefore, instead of using something like this:
$Conf{BackupFilesExclude} = {
'*' = [
'/Documents and Settings/*/Local Settings/Temporary Internet Files/',
'/Documents and Settings/*/Local Settings/Temp/',
'/Documents and Settings/*/NTUSER.DAT',
'/Documents and Settings/*/ntuser.dat.LOG',
],
};
you should use this:
$Conf{BackupFilesExclude} = {
'*' = [
'\\Documents and Settings\\*\\Local Settings\\Temporary Internet Files',
'\\Documents and Settings\\*\\Local Settings\\Temp',
'\\Documents and Settings\\*\\NTUSER.DAT',
'\\Documents and Settings\\*\\ntuser.dat.LOG',
],
};
Also, you shouldn't include the trailing \ at the end of the path.
You should either use:
'\\FOO'
or
'\\FOO\\*'
The first will exclude \FOO and all its contents. The latter will
include the directory \FOO but similarly exclude its contents.
You can experiment with what works or doesn't work by manually
running smbclient, eg:
setenv PASSWD XXX
/usr/bin/smbclient HOST\\SHARE -I IPADDR -U USERNAME -E -N -d 1 \
-c tarmode\ full -TcrX - \
\\Documents\ and\ Settings\\\*\\Local\ Settings\\Temporary\
Internet\ Files \
\\Documents\ and\ Settings\\\*\\Local\ Settings\\Temp \
\\Documents\ and\ Settings\\\*\\NTUSER.DAT \
\\Documents\ and\ Settings\\\*\\ntuser.dat.LOG \
| tar tvf -
Note the additional escaping for the shell. (Also, the -I IPADDR is
optional depending on your configuration.)

Re: [BackupPC-users] Translating BackupPc to another language
Fatih writes:
I want to translate BackupPc's CGI and the installation part from
English to Turkish.
How can i do this ? Is there anyone who is responsible for this kind
work ? Who can me give some advice where i could begin start
You should look in lib/BackupPC/Lang. Each language has its own
file. You can copy copy en.pm (English) to tr.pm (Turkish) and
then edit it with the translation of each string. Don't change
any of the html or variable names prefixed by $ - just the
English text.
To test your translation set $Conf{Language} to 'tr'. You also should
add 'tr' to the definition of Language in lib/BackupPC/Config/Meta.pm
so that choice is displayed in the CGI interface. The new file name
also has to be added to makeDist in CVS, which I can do. The makeDist
script does a lot of consistency checking of the language files, so it
would be good if you could run that too.
Before you start you should be sure you are committed to support
the translation updates for each new version. While the on-going
work is actually very small, each new translation means there is
an increasing amount of work when I change the CGI interface to
get everyone to update their translations. In fact, two of the
language files - Spanish and Portuguese-Brazilian - still have
English snippets prefixed with ENG. It would be great if any
fluent list member can send me diffs for those strings.

You have a high log level enabled ($Conf{XferLogLevel}), so you will
get a lot of debug messages.
This message is normal. It says the size of the file on the client
doesn't match the size on the server. When the file isn't on the

the server file size is 0 versus 14702080 on the client.

Looking at the source of the Beta, this looks like the changes were not implemented. Was it just missed, or is there another reason? This is fixed but somehow I didn't add it to the ChangeLog. Bernhard Ott and Tino Schwarze debugged the problem. I'll update the ChangeLog for the next release. Look at the dirRead() function in lib/BackupPC/Lib.pm. It does the check at runtime (when $TopDir is known). In 3.1.0 the bug was that the check was done at startup (in the BEGIN block) on the directory that BackupPC was started in, not $TopDir (which is often a different file system).

I presume you are trying to include just /folder1 and /folder2
on the D$ share, right?
If you are using the CGI interface it can be a bit confusing.
For $Conf{BackupFilesOnly} the key should be D$ and the
values should be the paths (relative to the share).
The actual setting in the config.pl file should look like this:
$Conf{BackupFilesOnly} = {
'D$' = ['/folder1', '/folder2'],
}
Please tell us the relevant config settings you have, and also
include the first few lines of the XferLOG file so we can see
exactly what command is being run.

[BackupPC-users] BackupPC 3.2.0beta0 released
BackupPC 3.2.0beta0 has been released on SF.net.
3.2.0beta0 is the first beta release of 3.2.0.
3.2.0beta0 has several new features and quite a few bug fixes
since 3.1.0. New features include:
* Added FTP xfer method, implemented by Paul Mantz.
* Added more options to server backup command: rather than just forcing
an incremental or full backup, a regular (auto) backup can be queued
(ie: do nothing/incr/full based on schedule), as well as doing just
an incremental or full or nothing based on the client schedule.
Based on patches submitted by Joe Digilio.
* Added $Conf{CmdQueueNice} to specify nice level for command queue
commands (eg: BackupPC_link and BackupPC_nightly). Suggested by
Carl Soderstrom.
* Changed bin/BackupPC_dump to not ping or lookup the host if
$Conf{BackupsDisable} is set. Requested by John Rouillard.
* Added variable substitution for host, confDir, client in
RsyncArgs, and also added option RsyncArgsExtra to allow
more easy customization of RsyncArgs on a per-client basis.
Proposed (with patch) by Raman Gupta.
* Added Xfer error column to the host summary table in the CGI
interface. Based on patch submitted by Jan Kratochvíl.
See the ChangeLog below for full details.

#
# Version 3.2.0beta0, 5 April 2009
#
* Added BackupPC::Xfer::Protocol as a common class for each Xfer
method. This simplifies some of the xfer specific code.
Implemented by Paul Mantz.
* Added FTP xfer method, implemented by Paul Mantz.
* Added BackupPC::Xfer module to provide a common interface to the
different xfer methods. Implemented by Paul Mantz.
* Moved setting of $bpc-{PoolDir} and $bpc-{CPoolDir} after the
config file is read in BackupPC::Lib. Fix proposed by Tim Taylor
and Joe Krahn, and rediscovered by several others including
Holger Parplies.
* Create $TopDir and related data directories in BackupPC_dump
prior to hardlink test. Requested by Les Stott.
* Fixed encoding of email subject header in bin/BackupPC_sendEmail as
suggested by Jean-Claude Repetto. Also changed $Conf{EMailHeaders}
charset to utf-8. Also changed bin/BackupPC_sendEmail to not send
any per-client email if $Conf{BackupsDisable} is set.
* Modified bin/BackupPC_dump to fix the case of a single partial
backup followed by a successful incremental resulting in a full
backup of level 1, rather than level 0. Reported by Jeff
Kosowsky.
* Fixed BackupPC::PoolWrite to always create the parent directory.
This fixed a case with rsync/rsyncd where a file like -i in the
top-level directory sorts before ., which meant the directory
creation is after the file creation. Also PoolWrite errors now
increment xferError count. Reported by Jeff Kosowsky.
* BackupPC now gives a more useful error message if BackupPC_nightly
takes more than 24 hours (ie: when the next one is meant to
start). Reported by Tony Schreiner.
* Added more options to server backup command: rather than just forcing
an incremental or full backup, a regular (auto) backup can be queued
(ie: do nothing/incr/full based on schedule), as well as doing just
an incremental or full or nothing based on the client schedule.
Based on patches submitted by Joe Digilio.
* Modified lib/BackupPC/CGI/RSS.pm to replace \n with \r\n in the RSS
http response headers. Patch submitted by Thomas Eckhardt.
* Modified bin/BackupPC_archive to allow the archive request file
name to contain spaces and dashes, requested by Tim Massey.
* Fix to configure.pl for --no-fhs case to initialize ConfigDir
from Dan Pritts. Also changed perl path to #!/usr/bin/env perl.
* Modified bin/BackupPC_archiveHost to shell escape the output file
name. That allows it to contain spaces and other special characters.
Requested by Toni Van Remortel. Also updated bin/BackupPC_archiveHost
to shell escape and check other arguments.
* Added $Conf{CmdQueueNice} to specify nice level for command queue
commands (eg: BackupPC_link and BackupPC_nightly). Suggested by
Carl Soderstrom.
* Added --config-override to configure.pl, allow config settings to be
set on the command line. Proposed by Les Stott and Holger Parplies.
* Moved call to NmbLookupFindHostCmd in BackupPC_dump to after the
check of whether a backup needs to be done. This makes wakeonlan
work correctly, rather than waking up the client every WakeupSchedule.
Reported by David Lasker.
* Improved settings for compression and compext in BackupPC_archiveStart
based on compression type, as proposed by Paul Dugas. compext is now
empty, .gz or .bz2 based on ArchiveComp.
* Changed bin/BackupPC_dump to not ping or lookup the host if
$Conf{BackupsDisable} is set. Requested by John Rouillard.
* Changed BackupPC_tarCreate to disable output of final nulls in
tar archive when -l or -L option is used. Reported

Ah, yes, you are requesting an extra layer of escaping with:

Since you are executing rsync directly, you should use this:

Re: [BackupPC-users] Local backups
Paul writes:
I tried just changing 'RsyncClientCmd' to $rsyncPath $argList+ but it
seems BackupPC is expecting the SSH and is now improperly escaping
'RsyncArgs'. The hitch is with a space in one.
$Conf{RsyncClientCmd} = '$rsyncPath $argList+';
$Conf{RsyncArgs} = [
'--numeric-ids',
'--perms',
'--owner',
'--group',
'-D',
'--links',
'--hard-links',
'--times',
'--block-size=2048',
'--recursive',
'--filter',
'dir-merge /.backuppc-filter'
];
The last two are an addition I use to allow users to exclude files from
the backup with properly crafted .backuppc-filter files in their
directories.
I end up with an extra slash after the dir-merge.
/usr/bin/rsync --server --sender --numeric-ids --perms --owner --group
-D --links --hard-links --times --block-size=2048 --recursive --filter
dir-merge\ /.backuppc-filter --ignore-times . /etc/
The \ is to escape the following since it is a single argument.
Actually, BackupPC doesn't execute the command as printed. Rather,
it keeps the arguments as an array and passes them directly to exec().
So rsync should see a single argument
dir-merge /.backuppc-filter
right after '--filter'.
For logging purposes, the command is turned into a single string and
escaped as though it was going to be executed by a shell (although it
isn't). That's when the \ gets added.

Yes, this looks like a bug. An error will be written to the per-client
LOG file. But in this case the XferLOG file isn't closed before exit,
so the cached compressed data isn't written, nor is the file renamed to
XferLOG.bad.z. So as you noticed you just have an empty XferLOG.z file.
It's very easy to fix... in BackupPC_dump just call BackupFailCleanup()
instead of exit(1) in the cases where DumpPreUserCmd (or any *UserCmd)
fails.

Appreciate any ideas or hints on what could be happening and what I need

First, it would be helpful if you can reduce the backup to a
relatively small set of files (a few thousand is still ok) that
still shows the problem.
Then set $Conf{XferLogLevel} to 5, email me the resulting XferLOG.z

Re: [BackupPC-users] move a specific backup (share) from one pool to another pool
sabujp writes: In the last command that runs BackupPC_tarPCCopy, does this perl command look at any of the configuration files on the local host or does it just get what it needs to re-generate the hard links straight from the old pc directory? I looked through the code and don't see that it does look at the local system's backuppc configuration files under /etc/BackupPC . It shouldn't look at the config files beyond extracting the TopDir. What I'm doing is the following: I have two BackupPC servers host1 and host2. I'm copying the BackupPC directories from a SAN (san2) attached to host2 to the SAN attached to host1 (san1) . Both SANs are available to both hosts through a FC switch so I just umount it on host2 and re-mount it on host1. I then copy the cpool and pool directories to host1's san1. After this is finished I plan on running BackupPC_tarPCCopy on host1 (san1) against the pc directory on san2. Just wanted to make sure BackupPC_tarPCCopy wasn't going to look at host1:/etc/BackupPC/hosts and try something funny . I'm not sure I fully understand what you are trying to do, but it is critical that the cpool directories are identical on the source and target trees before running BackupPC_tarPCCopy. That's because the hardlink structure is deteceted on the source tree, and just the cpool path is sent to the target tar -x so it can create the same hardlink. The cpool files themselves are not transferred by BackupPC_tarPCCopy. I don't think there is a way to transfer a single host's backups using BackupPC_tarPCCopy.

Re: [BackupPC-users] BackupPC calls NmbLookupFindHostCmd every hour messing up wakeonlan
David writes: I took a closer look at the perl code and I see the cause of the problem. Please note I have no DNS. My PCs use DHCP, but are configured in BackupPC with the host table's DHCP flag set to zero. Here is what I think is happening: 1. BackupPC_dump is called periodically at each WakeupSchedule interval. 2. BackupPC_dump calls NetBiosHostIPFind which uses NmbLookupFindHostCmd to lookup my hosts' Samba names, thereby powering them on. 3. It then determines whether or not the host needs to be backed up. At this point the only solution I can think of is to modify BackupPC_dump's perl code to reverse the order of steps 2 and 3 above, and only invoke wake-on-lan if a backup is due. I am hoping a more experienced BackupPC user has a better solution that doesn't involve modifying the perl code. You're right - these two steps are backwards and it should be fine to do them in the order you propose. However, I can't suggest a way to do it without modifying the code. I will fix this. An alternative is just doing a single wakeup each night, but that won't work for laptops that aren't connected overnight. Or you could do two: one at night and one during the day, minimizing the likelihood of an extraneous power up.

You have a typo. The share name is /srv, not srv, so you need:
$Conf{BackupFilesExclude} = {
'/srv' = [
'file1',
'/bu'

Also, you are excluding files below /srv, but not /. You need
to either restrict rsync with --one-file-system or exclude /srv
under /.

The idea is you can copy and edit BackupPC_archiveHost to add

Re: [BackupPC-users] how to restore one extra file if a restore is requested
Matthias writes: If a user requests a restore I want to restore one extra file and handle it by the RestorePostUserCmd. Is it possible to request this additional restore with BackupPC_restore during the RestorePreUserCmd or RestorePostUserCmd ? Yes, you could do it by emulating what the CGI interface does. You will need to write a perl script that would create a restore request file using Data::Dumper (see the CGI code for an example), and then issue a restore command using BackupPC_serverMesg. Be careful you don't end up with an infinite loop, where the second restore triggers a third, etc... See bin/BackupPC_archiveStart for an example of the basic steps, since this script does a similar thing for archives as you want to do with restores.

It appears that that have changed the way smbclient works with version 3.2.3,
and it is causing this problem. A problem identical to yours was reported as
being a bug in Ubuntred 8.10 (Intrepid):
https://bugs.launchpad.net/ubuntu/+source/backuppc/+bug/283652. However, the
actual source of the problem is smbclient, which is called by backuppc.
Therefore, I reported a second bug: https://bugs.launchpad.net/bugs/297025 that
will hopefully fix the problem.
The solution to your backup problem is to edit /etc/backuppc/config.pl on
server #2, which is using backuppc version 3.1.0 and smbclient 3.2.3. Do not
make this modification to server #1, as it will break it.
There are three strings that you need to modify in config.pl:
$Conf{SmbClientFullCmd}
$Conf{SmbClientIncrCmd}
$Conf{SmbClientRestoreCmd}
which control Samba backups and restore. In all three strings remove the -N
flag.
My understanding that the flag is no longer needed, because the login prompt is
automatically suppressed by smbclient when backuppc passes the password through
the PASSWD environment variable. But for some unfathomable reason, when the
-N flag is used, the password does not get passed to Windows' LAN Manager.
Good luck.

Re: [BackupPC-users] Status of fuse for viewing backuppc backups
Jeff Kosowsky writes: I had been thinking of writing code to implement a robust fuse filesystem for BackupPC backups but then I saw that John Craig (and perhaps others) had started to write code. While the code still seems to be at the proof-of-concept I think the idea is very powerful and extensible. I agree. I've been following the suggestions and proof-of-concept code with interest. I actually believe having a FUSE implementation that supports writing would be the best way to support rsync 3.x (and any other xfer methods for that matter). Assuming the performance was ok, the time-reversed delta format for storing backups that I'm planning for BackupPC 4.x would be most easily implemented with FUSE. I've been working on various CVS checkins for a 3.2.0 release (finally!), so I haven't had a chance to play with FUSE, other than installing it and perl FUSE on my CentOS 5.2 system. One question I'm curious about: if FUSE becomes a required part of BackupPC 4.x, does that unduly complicate installation or reduce the number of distros that BackupPC can readily run on? I realize FUSE is standard on recent 2.6.x kernels, but CentOS 5.2, as one example, doesn't enable FUSE, and it was actually quite a pain installing it, since the rpm package I found didn't install the kernel module.

Re: [BackupPC-users] Using perl code within config files
Jeffrey writes: Just as an FYI, it is possible to use perl code within config files so that you can use a single config file yet still customize configurations by pc (or groups of pc's) without having to duplicate changes across multiple relatively similar config files each time you change a parameter. For example, I have a number of windows machines and one linux server. For the windows machines, I use a single config file in /etc/BackupPC/pc and then create links to it for each of my windows machines. I then use perl conditional statements to make some configurations unique by pc (or group of pc's). The trick is that $ARGV[0] is the name of the config file (or link) called and thus can be used to determine the machine. Personally, I find this trick very helpful... Yes, a nice trick. But there are two caveats: - the CGI editor won't preserve any of the in-line perl code - re-writing a config file (when upgrading with configure.pl and the CGI editor) might break since the in-line perl formatting might not be interpreted correctly.

Re: [BackupPC-users] Question about attrib file structure
Jeffrey, Sorry about the delay in replying. I've been really busy lately. 1. If a directory is *empty*, is there any reason for it to have an attrib file? Because in playing around with creating and deleting directory contents, I found that sometimes even after emptying directory contents, the subsequent incremental backups may sometimes still have (empty) attrib files. I believe there is always an attrib file created. It would be a minor optimization not to write empty attrib files. 2. If not, can I safely erase any (empty) attrib file that has no files associated with it? Yes. If there is no attrib file the necessary meta-data is created by reading the directory. If it is empty then the effect will be the same as an empty attrib file. 3. Other than type=10 (delete), is there *any* reason for an attrib file to contain an entry for a file that is not present in the directory? No other files should be in the attrib file: files that are there plus type=10 (delete).

Re: [BackupPC-users] How do you lock BackupPC from running?
Jeffrey writes: For the part of my routines BackupPC_fixLinks and BackupPC_deleteFile that actually try to make new links (or delete old ones), I would like to make sure that nothing else is creating or deleting links to the pool to avoid collisions. Specifically, I would like to be able to do the following: 1. Query the server whether it is free 2. If free tell the server to not launch anything else (i.e place equivalent of lock file) 3. Tell server when it can go back to launching other things (i.e. remove lock file). I assume that BackupPC_nightly and BackupPC_link must do similar things but I couldn't quite figure out how. First this should be on the devel rather than user list. The BackupPC server maintains queue (CmdQueue) for commands that need to be run one-at-a-time (currently BackupPC_link). The BackupPC_nightly policy is hardcoded (ie: first wakeup when current command from CmdQueue is done). So you could add a server message that adds your command to CmdQueue and it will be run serially with other BackupPC_links and not overlap BackupPC_nightly.

Yes, you're right.
Also, James, in 3.x the excludes are not passed in the
command-line to the remote rsync. They are sent via the

This has now provided access to the file BackupPC_archiveStart which I intend to use via cron as outlined in the BackupPC documentation. When executed from the command line this produces an archive in .tar.raw format rather than gzip format. I must be going snow blind on this as I simply cannot figure out what configuration entries need to be made in which files to achieve this. I am now totally confused and cannot make progress by using the documentation. Is anyone willing to give me a hand with this? BackupPC_archiveStart is hardcoded to have no compression and use a .raw suffix. It's pretty easy to see where to edit it to change that. As Nils' mentioned you can easily compress that file, or use BackupPC_tarCreate and compress its output (after all, BackupPC_archiveStart eventually just runs BackupPC_tarCreate).

This doesn't actually disable user requested backups - it just

Re: [BackupPC-users] Is there any way for BackupPC to restore hard links properly?
Jeffrey writes: Looking at the code and the structure of the storage and attrib files, it doesn't seem like there is any way for BackupPC to record and restore hard links. Not true. Hardlinks are stored without using hardlinks. Hardlinks are stored just like symlinks. The attribute type is BPC_FTYPE_HARDLINK and the contents of the file is the path of the file being linked to. For example, if there are 4 links to a file, one instance (it doesn't matter which - depends on the Xfer Method) will be stored as a regular file. The remaining three instances will be stored as type BPC_FTYPE_HARDLINK with pointers to the first file. Note that this is independent of the hardlinks used to de-duplicate. There is one subtlety with rsync: it also needs to remember if a regular file is the target of (other) hardlinks so that the correct file list can be generated during a restore. This is done by using an extra bit in the file's mode stored in the attrib file. This results in one subtle bug that can't be easily fixed: if you switch the Xfer method from tar to rsync, old backups that have hardlinks stored with tar won't be correctly restored with rsync. The workaround is generate a tar file and extract it, or switch the Xfer method back to tar before you do the restore. The opposite case should work correctly.

It's generally not important to back this file up, so if that is the problem you can just exclude If there is a small change to such a file it is quite likely to be more expensive than the original complete transfer.

Re: [BackupPC-users] Duplicate files in pool with same CHECKSUM and same CONTENTS
Jeffrey writes:
Except that it my case some of the duplicated checksums truly are the

Yes. Just as Holger mentions, if the hardlink attempt fails,
a new file is created in the pool. You appear to have some
unreliability in your NFS or network setup.
The only other time identical files will have different pool
entries, as people noted, is when $Conf{HardLinkMax} is hit.
Subsequent expiry of backups might cause the identical files
to move below $Conf{HardLinkMax}.
It's not worth the trouble to try to combine those files since
the frequency is so small and the effort to relink them is very
high.

Re: [BackupPC-users] Pool duplicates and corrupted backups
Jeffrey writes: Types of Duplicate checksums: 1. Same checksum but contents differ -- INTENTIONAL - nothing to fix Right. 2. Same checksum and compressed content I have found many of these but contrary to my earlier postings the ones that I examined were not in my error log so they don't seem to be due to the nfs/link problems (see later) I don't know what the source of these are though... This could happen if there is ever a read error of a file in the cpool. Before linking to a cpool file (except when rsync is used with checksum caching enabled and the checksums match exactly), the contents are read, decompressed and compared to the incoming file. Any read error will cause the match to fail and a new cpool file will be written. 3. Same checksums, different compressed content, same zcatted content As per my earlier email, I found at least one of these and am not sure why they even exist. This can happen if one file has rsync checksums and the other does not. This would happen after case 2 above. The checksums don't get added until the next time the file is read. This can also happen since the mapping of file - file.z is one-to-many: there are many different ways to compress a file that all uncompress the same. But that shouldn't happen in BackupPC unless you change the compression level. 4. Files with *NO* pool entries. This seems to be what occurs with the files in my error log that cite the failure of MakeFileLink Yes. There are cases when it just leaves the file there (below pc/HOST/nnn) without linking to the pool. The deeper I probe into this, the more confused I get and the more I worry about data integrity on my system... Look, you *do* have a data integrity problem, and yes, you should worry. There is no further value in understanding symptoms from a relatively filesystem-intensive application like BackupPC and working backwards. You need to fix your hardware/software before using BackupPC again.

That isn't good. This is the case where it is doing a random check
of the cached checksums (based on $Conf{RsyncCsumCacheVerifyProb}).
I am missing an error check just prior to this line of code. An
error will occur if there is some problem open/reading the cached
checksum information. A possible cause might be some file system
corruption.
I'd be curious what the error is. Just prior to this line
you could add this code:
if ( $err ) {
$fio-log(Can't get rsync digests from $attr-{fullPath}
. (err=$err, name=$f-{name}));
$fio-{stats}{errorCnt}++;
return -1;
}
Alternatively, just set $Conf{RsyncCsumCacheVerifyProb} to 0. This
code will be skipped, and I suspect it will fail further down and
there is an error check there. Seeing the error number would be
helpful.
I would also try removing the --checksum-seed=32761 option from
$Conf{RsyncArgs} and trying the backup again. This will disable
the use of cached checksums.

I'm replying to this old thread because I believe that my question/commentary
fit here better than in any other thread regarding this subject.
I'm using BackupPC to backup among others a samba file server that uses a
ISO8859-1 charset. To get the characters displayed correctly in the command
line I have to set BackupPC's ClientCharset to ISO-8859-1. That's fine. But
when I try to download a file to a Ubuntu/Windows desktop I've got encoding
problems.
Using the option -e UTF8 with BackupPC_zipCreate in the command line
works. But to get it working from the CGI interface I had to hard coded it
in lib/BackupPC/CGI/Restore.pm :
--
$bpc-cmdSystemOrEvalLong([$BinDir/BackupPC_zipCreate,
-h, $host,
-n, $num,
-c, $In{compressLevel},
-s, $share,
@pathOpts,
@fileList, # add the ,
-e UTF8 # HERE
],
sub { print(@_); },
---
I'm sure this is not the best way to do it but I haven't had success
with any other try I did. Does anybody known a better way to do that ?
I added the command-line argument for charset but didn't implement
a CGI setting. The problem I have is I can't find any documentation
for zip files and any standards around charset encoding for the
file names in a zip file. Is utf8 the correct default, or does
it depend on which platform is trying to unpack the zip file?

Re: [BackupPC-users] BackupPC_archiveStart not using compression
Stephen writes:
When I run BackupPC_archiveStart from the command line it's not
using compression for the backup, the backup file is created using
raw, however if I start the archive job via the web-interface it
uses compression (gzip by default).
The command I am running is:
/usr/share/backuppc/bin/BackupPC_archiveStart offsite-archive backuppc nphts
Looks like a typo in bin/BackupPC_archiveStart. This line:
compression = $bpc-{Conf}{CatPath},
should be
compression = $bpc-{Conf}{ArchiveComp},
Or slightly more correctly, if $bpc-{Conf}{ArchiveComp} is none
you should set compression to $bpc-{Conf}{CatPath} instead.
You might also want to change the value of compext
when compression is on.

Re: [BackupPC-users] How to get a remote script to log output in the backup logs

The error is benign, but it means that the previous
BackupPC_nightly hasn't finished running. It looks like you
have set $Conf{MaxBackupPCNightlyJobs} to 8. You are likely
disk seek limited, so that high a value won't help.
It's probably better to increase $Conf{BackupPCNightlyPeriod} to 4
or more.

Re: [BackupPC-users] next version ?
Philippe writes: I went to the sourceforge site and noticed that the last update of ths cvs was 9 month old. Does it mean that developpement stopped or that the next version is not on this server ? I don't use the SF CVS site very actively - I tend to do batch updates closer to the release time. Other developers coordinate either directly with me or in some cases do use CVS. I have been particularly busy this year and my time for BackupPC development has been reduced. However, I've been thinking more about major features for BackupPC 4.x and I'm definitely looking forward to being able to spend more time on this in the future. I particularly want to change the way backups are stored so that the only complete/filled backup is the most recent (whether or not it is a full or incremental), and all prior backups are stored as reverse-time deltas. This has a number of significant benefits. There has been some good discussion around this over the last couple of years. Starting a few months ago Zmanda began funding a developer, Paul Mantz, to work on BackupPC. He's developing an FTP XferMethod, and also taking that as an opportunity to learn more about the architecture. His work will likely be the basis of a 3.2 release. Bottom line, BackupPC development is certainly continuing.

After that I was able to backup the windows machine using backupPC :).
Thanks for the closure on this issue.
This does make sense if your password contains characters like '$' that perl
interpolates inside double quotes. You don't need to confirm that.
You wouldn't have had this problem if you used the cgi editor.

Re: [BackupPC-users] Strange behavior when using backuppc with rsyncd or rsync+ssh
Louis-Marie writes: I also have a remark about backuppc pooling feature: I think the server locally detects file duplicates by hashing them after download. As far as I know, rsync should also be able to send some kind of hash from remote host before download. Wouldn't it be possible to detect duplicates using this hash before the file is downloaded? This would for example save downloading files again when a user simply renames a directory... Rsync only efficiently transfers changes to files that have the same path. Rsync does not detect renamed files - it does a complete transfer in that case. (Some work was done patching rsync to do fuzzy matching to try to find some renamed files.) BackupPC uses the efficiency of rsync transfers, and then globally matches identical files. A renamed file will be verbatim transferred and then matched to the pool. If the rsync transfer determines the file is identical, BackupPC simply adds a hardlink. If the rsync transfer notices even a small change to a file, just the change will be transferred, but then BackupPC needs to reconstruct the full file to determined whether a match is in the pool.

Re: [BackupPC-users] nmblookup being invoked for hosts where backups are disabled (bug)
John writes:
We were having a weird problem with nmblookup firing for a host that
was disabled with:
$Conf{BackupsDisable} = '2';
using BackupPC 3.1.0. The same thing happend when set to 1. My claim
is that BackupPC shouldn't be attempting to resolve any host with
BackupsDisabled set to 2, and it should not be looked up when it is
set to 1, unless a user explicitly requests that the host be backed
up. (I.E. it shouldn't be queued just because it's in the hosts file.)
It still gets queued because there might be backups that need to expire.
You are right - the disable check happens after the host alive check.
It was done that way to handle the dhcp = 1 case (where you don't know
which host it is until you run nmblookup).
But in the normal case that check should be done earlier. I'll add
that to the todo list.

BackupPC should parse this last line and extract 0.138msec as
the round trip time.
To see exactly the command it is running and the output it gets,
run:
su backuppc
BackupPC_dump -f -v shipping
Hit ^C after you get past the ping output and parsed result.
What ping output do you get?
In the mean time increase $Conf{PingMaxMsec} to get backups
running again.

Is this the right way to go about this:
$Conf{BackupFilesExclude} = ['/proc', '/sys', '/mnt', '/opt'];
$Conf{BackupFilesOnly) = '/opt/zimbra/backup';
Assuming you only want to backup that one directory and nothing
else, since all the excludes are outside/above the one directory
you want all you need is:
$Conf{BackupFilesOnly) = '/opt/zimbra/backup';
Leave $Conf{BackupFilesExclude} empty.
An alternative is to use '/opt/zimbra/backup' for $Conf{TarShareName}
and leave both $Conf{BackupFilesOnly) and $Conf{BackupFilesExclude}
empty.
