I am now facing the problem: Error: Wrong user: my userid is 70, instead of 502(backuppc) when communicating with the CGI. As I understand it I need (for performance) a seperate instance of Apache running as user backuppc in order to be able to use the mod_perl method (that also gives me the highest performance), as opposed to (much slower) setuid method… I have searched the archives and google, but not found adequate help. First note that the performance difference only affect using the web browser to view/restore backups, something you probably don't do that often, not the performance of the backups operations which happen separately. Also, if you don't have any other web sites on the same server, you could simply set up backuppc to run with the same id as the web server. I can't help with setting up another apache instance but usually it involves duplicating whatever the stock configuration does but using a different port number to avoid conflicts. I'd first try the simple CGI setup and see how performance is. I've never felt the need to change the setup into a more complicated mod_perl setup to speed up the web interface, as performance is just fine for us using the plain CGI version. It doesn't feel slow at all. Sure, if I'd go and measure performance, mod_perl will probably be better, but backups won't complete any faster. As Les said: it's just the web interface.

[BackupPC-users] BackupPC sometimes stops doing backups
Hello all, Sometimes I notice BackupPC stops doing backups. BackupPC doesn't send out any notifications about this. The BackupPC daemon is running, but when I stop it and try to start it again, it suddenly complains about not being able to create the test hardlink. # service backuppc status BackupPC (pid 22421) is running... # service backuppc stop Shutting down BackupPC:[ OK ] # service backuppc start Starting BackupPC: 2009-02-24 15:10:00 Can't create a test hardlink between a file in /mnt/backup/pc and /mnt/backup/cpool. Either these are different file systems, or this file system doesn't support hardlinks, or these directories don't exist, or there is a permissions problem, or the file system is out of inodes or full. Use df, df -i, and ls -ld to check each of these possibilities. Quitting... [FAILED] After an fsck run BackupPC will start again. Of course I don't expect BackupPC to do backups on a filesystem that has problems, but I also don't like that it just sits there silently and doesn't warn me of this condition. Could this somehow be improved?

In the web interface (which is how I added the exclusions), it simply

The web interface is a bit confusing there. Just keep in mind that
the

If you define the key as '*', it will apply the exclusions to all

Technically not all shares, but all shares that don't have any

understanding
is that, in your configuration file, you can set it to any value you

as long as you stay within the file-system that contains the backuppc

The thing is that the TopDir location is also written into some lib
file at install time. If you install a BackupPC package the same thing
applies: if you just change it in the config file, it won't work.
From memory, here are the 2 principal alternatives for using a
directory on another file-system:
1. mount - as already suggested - your backup file-system directly at
the mount point /var/lib/backuppc
2. do a bind-mount of the backup file-system
- mount your backup file-system at the mount point of your
choice,
e.g. backup-mount
- do mount --bind backup-mount /var/lib/backuppc
to have this done automatically at boot time, add a line to your
/etc/fstab file
- backup-mount /var/lib/backuppc none bind
You can also use a plain symlink. These solutions have been posted
many times to this mailinglist.

Surely the distributor is doing its best to deliver a nice experience, but some tools (like both CentOS and BackupPC as far as I'm concerned) just have too many knobs and switches to satisfy every level of requirements a user can have out of the box. You talk about BackupPC like it's logical that it is configured exactly for your needs. But you just seem to want to play a little music and have backups. That's fine, but other people are using BackupPC in an enterprise situation with large RAID storage arrays. Some people backup mostly Windows machines, some people backup no Windows machines. Some backup their machine to a local drive, some backup racks of servers over the internet. There are just a lot of situations where BackupPC can be put to use, but that also means there'll be some configuring to do. Your definition of 'essential' might just be very different from someone else's. I know BackupPC's web interface is pretty shiny, but maybe you're just looking for a tool that has less knobs and switches. Check out rdiff- backup for instance.

If you cannot SSH into the machines, you cannot run backups over SSH. It's just a matter of language, I guess. When you say you can SSH into the machines I take that to mean that you can say ssh remote machine I suspect that is what most newbies to backuppc (like me) will think, which is probably why the official documentation is hard to untangle. I gave an example that read 'ssh usern...@client', not 'ssh client'. The public key of the backuppc user needs to be in the authorized_keys file of the user account on the client.

At the link I mentioned above. http://backuppc.sourceforge.net/faq/ssh.html says: Key exchange To allow BackupPC to ssh to the client as root, you need to place BackupPC's public key into root's authorized list on the client. (...) You say it is standard procedure; but it is not normal to ssh into a machine as a different user, Why not? You login as the user you want to login as. and in the case of backuppc it is not clear that this is what is being done, unless one looks behind the scenes. I thought that was pretty clear actually. If you want to login as a specific user which is different from the username you are currently logged in as, you have to somehow tell ssh. No way around that. In my view, BackupPC is an excellent program, with two large provisos: the documentation is very bad, I disagree completely. The docs on the site are excellent in my view. Much better than for a lot of other open source tools I use. Do you know about the BackupPC wiki? You can post clearer instructions there if you have any. Or ask Craig to include specific changes. and the error messages (the 4 bytes nonsense) are even worse. That one might be hard to tackle at first, yes.

Re: [BackupPC-users] BackupPC_link got error -4 when calling MakeFileLink
Juergen Harms wrote: I fought these messages yesterday. In my case the reason is that topDir - the directory where the backup data is stored - is a separate file-system, and that BackupPC has problems dealing with that situation. Having topDir on a separate filesystem is actually recommended for performance (you can mount it noatime for instance). BackupPC had no problems whatsoever with this situation in my case. Googling provided 2 alternative solutions (there appears to be quite an epidemy of people suffering from this problem): 1. Make /var/lib/backuppc an empty directory (if currently you have data there, start by saving it elsewhere), and than mount your topDir file-system at /var/lib/backuppc (also documented in http://www.cs.umd.edu/~cdunne/projs/backuppc_guide.html). 2. Use the --bind option of mount (the Google reference suggests -o bind, I guess another and probably obsolete flavour of --bind, not documented on my Mandriva platform). I start by mounting my file system for backup data quite traditionally at the mount point /backup, but after that I add an additional mount instruction: mount --bind /backup /var/lib/backuppc That acts like a hard link between /backup and /var/lib/backuppc - you see the same data through either mount point (and, evidently, you must again start by saving any data at /var/lib/backuppc) - and BackupPC appears to be happy, no more error messages. You will probably want to avoid the explicit mount --bind ... instruction: this is done by adding to your /etc/fstab - I placed it directly after the mount /dev/xxx /backup ... instruction - the following line: /backup /var/lib/backuppc none rw,bind 0 0 with the result that the 2 mount points get mounted at boot time. I also changed owner and group of /backup to the backup user - but there I am less sure how correct or imperative that is. I read that a new release (3.1.1) of backuppc is being prepared - short of fixing this problem, it might be a good idea to add a couple of words to the documentation, warning about this restriction in the configurability of the topDir variable. What solution are you proposing exactly? AFAIK BackupPC doesn't care if topDir is on another filesystem or not and how it is mounted. Just make sure the filesystem it's on supports hardlinks and that your backuppc user can access topDir and it should just work. It did for me.

Re: [BackupPC-users] Specifying DHCP client addresses
Juergen Harms wrote: I am trying to plan my first backupPC installation and have a question on how to set up the backupc/host file (Mandriva 9.0, intending to use rsync). The How BackupPC Finds Hosts section in the documentation is very clear: for DHCP hosts I should set the DHCP flag to 1 and then will get NETBIOS name resolution (rmblookup). That means, that I need to install a samba server on each DHCP client - which is an overkill and an undesired complication, I do not need samba if I use rsync. 2 questions: 1. If the /etc/hosts files on the server and clients contain the correct IP addresses, can I than simply set the DHCP flag to 0 and fake using static addresses, even if a host has obtained its address via DHCP? 2. If yes, has anybody experience in using nmap for verifying/ correcting the /etc/hosts entries for use by backupPC? At present I use nmap (run as root) to get a list of valid name-IP address mappings for manually adjusting addresses if a DHCP laptop needs to assume certain server functions. It looks promising to digest this into an automatically run procedure. Most DHCP servers can be configured to hand out the same IP address to a machine every time. Have you looked into that? I'd go with either that or a proper DNS server.

Yes, your configuration is incorrect. See

but the keys in your example correspond to directories *within* a
share. This doesn't work.
You could solve this by using '/' (or '*', which sets excludes for all
shares don't have any specific excludes set) as the share name and
specifying a list of directories not to backup as the value:
$Conf{BackupFilesExclude} = {
'*' = [
'/media/*',
'/proc/*',
'/sys/*',
'/var/lib/backuppc/*'

};
I guess you could even use the simple list form in this case as you're
not working with multiple shares:
$Conf{BackupFilesExclude} = { '/media/*', '/proc/*', '/sys/*', '/var/
lib/backuppc/*' };

just backup /. If you want to backup everything, you don't need any
excludes. However, you probably don't want to backup everything, as
backing up /proc and /sys really doesn't make sense. The comments in

The only writes should be to the cache and to an attached database. I would suggest you do periodic dumps of the database and then backup the directory where you put those dumps. I would also suggest that you replicate the database to another machine. Keep in mind that if you are not going to have an hot spare database server, you can replicate a heavily used database to very modest hardware because it doesnt need to server requests. The nice thing about online replication is that you can replicate and then shut down the second database and do the dump from there so you never have to shut down the main database. I believe a lot of databases these days don't need to be shut down to create a dump. And we still don't know what the situation is (what kind of database, how much data).

Stuart Luscombe wrote: I’ve got the OS (CentOS) installed on the new server and have installed BackupPC v3.1.0, but I’m having problems working out how to sync the pool with the main backup server. I managed to rsync the cpool folder without any real bother, but the pool folder is the problem, if I try an rsync it eventually dies with an ‘out of memory’ error (the server has 8GB), and a cp –a didn’t seem to work either, as the server filled up, assumedly as it’s not copying the hard links correctly? So my query here really is am I going the right way about this? If not, what’s the best method to take so that say once a day the duplicate server gets updated. Check the archives for a *lot* of posts on this subject. The general conclusion is that copying or rsyncing big pools just doesn't work because of the large number of hardlinks used by BackupPC. Using rsync 3.x instead of 2.x seems to need a lot less memory, but it just ends at some point. A lot of people run into this when they want to migrate their pool to another machine or bigger hard drive. In that case the usual advice is to use dd to copy the partition and then grow the filesystem once it's copied over. dd'ing your complete pool every day isn't going to work either I guess. Instead of trying to sync the pool, can't you just run a second BackupPC server that also backs up your machines?

Re: [BackupPC-users] Configure TopDir per pc
Mark Adams wrote:
I have several machines I would like to backup with BackupPC, but the
server is a humble box with several installed hard discs -- nothing
fancy.
I need to backup each client machine to a different hard drive on the
server. I have one client configured and it tries to backup my 16
GB of
data, but fails because TopDir is configured for /var/lib/bacuppc in
my
/etc/backuppc/config.pl file and there simply isn't enough room for
the
data there. My reading of the docs says that I should be able to
configure TopDir in the client.pl file under
/var/lib/backuppc/pc/client/client.pl. I have done this:
# cat /var/lib/backuppc/pc/client/client.pl
$Conf{TopDir} = '/mnt/attic/spike_images';
$Conf{XferMethod} = 'rsync';
$Conf{BackupFilesExclude} = ['/floppy'];
$Conf{BackupFilesOnly} = ['/mnt/spike/images', '/mnt/spike/photos'];
$Conf{ClientNameAlias} = '192.168.xxx.xxx';
But it doesn't seem to make any difference. How can I set a TopDir
per pc?
You can't. BackupPC stores the files for the backed up hosts in a pool
that needs to be on one filesystem, because of the use of hardlinks.
The only way to use multiple pools (and have multiple TopDirs) is to
run multiple installations of BackupPC.
Another option: use LVM to make one volume spanning your drives.

success.
Asterisks are normally expanded by your shell to a list of files in
the current directory. I don't believe there is an 'all' option. You
could just list them, or grep/awk them from your hosts file or
something.
02 I would like to conduct actions prior and post creating an
archive. Specifically mounting a Truecrypt encrypted removable

executed at the command line as user = backuppc but fails when used
in archiveHost.pl.
Command line version
/bin/echo password | /usr/bin/truecrypt --text --keyfiles= --
protect-hidden=no --password=password --mount /dev/sdd1 /media/

archiveHost.pl version
$Conf{ArchivePreUserCmd} = '/bin/echo password | /usr/bin/truecrypt
--text --keyfiles= --protect-hidden=no --password=password --

Is this the correct file in which to list pre/post archive commands?
Is there a syntax flaw in the construction of my
$Conf{ArchivePreUserCmd}?
I believe your are going to run this as a cronjob, right? Why not make
a three line script (mount image, archive+gzip, unmount) and run that
from cron? Then you don't need to mess with any pre or post commands
in BackupPC. Just an idea.

Why do this? I have a network in which all user home directories

locally on each PC. The backups of the file-server are conducted
using the schedule facility of BackupPC. This setup is working
well. To make it simpler for each user it will be preferred if they

It only makes sense to support protocol 28 in File::RsyncP when features in BackupPC will use functionality only available with protocol 28. By the way, we are backing up machines that all run rsync 3.0.4 and support protocol 30, but we're using BackupPC with File::RsyncP, so the negotiated procotol is protocol 28 for all our backups. And our backups are working fine. But we're not backing up any Windows machines. My point PRECISELY -- Protocol 30 seems to be important to avoid hangs with long and/or weird file names in Windows. Since those file types don't exist in Linux, Protocol 28 works just fine there. What do you mean by saying that long and/or weird file names don't exist in Linux? Can file names be longer when using Windows than they can when using Linux? Can Windows file names be weirder? (If so, what does that mean exactly?) I'm not saying that it's not true that protocol 30 did not add functionality that somehow fixes your problem (because I'm not really up to speed on what the protocol differences are), but I just have this gut feeling that the protocol version is not the problem. Craig might be able to explain all of this better.

The most disturbing thing to me is that BackupPC seems to be so fragile in that if it encounters a problem, it seems to just hang there (seemingly) forever without sending any error messages I get error messages about things like network errors BackupPC encounters during backups. The error you're having doesn't sound like 'regular error' though and that's probably why you get irrgular behavior (hanging processes). Either you've hit a bug in BackupPC or your installation is broken, but that undefined value error shouldn't occur. Did you install BackupPC using a package manager? If so, can you verify the installation (e.g. rpm -V BackupPC if you installed an RPM)? and without even doing something like skipping the troublesome areas and moving on. Now that would be scary: would you like incomplete backups? Nils Breunese. P.S. Backing up MYI and MYD files of MySQL databases is not very useful, as they're not guaranteed to be in a consistent state when you back them up. Even if you backed them up succesfully you could have corrupt databases after restoring these files. Better create SQL dumps using the pre-dump command and backup those. - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/

I noticed some outdated documentation.
The 'Removing a client' section under 'Other installation topics' [0]
says to set $Conf{FullPeriod} to a negative value to disable backups
for a client. However, the documentation on $Conf{BackupsDisable} [1]
says:
In versions prior to 3.0 Backups were disabled by setting
$Conf{FullPeriod} to -1 or -2.
Could this be corrected?

With such a small pipe you will be able to realize some benefit to using maximum compression with rsync. 3) consider bumping up the available bandwidth. I buy DSL lines in many markets for my company and have never seen a situation where getting a 256Kb upload cost substantially more than a 128Kb link. 3a) sounds like you might be using ADSL, see if SDSL is available or see if there is a plan with more upload and the same download capacity. 4) consider changing the full backup script in backuppc to NOT use the no-times option that causes all of the files to be transfered. This would make this essentially an incremental backup that sticks around. I have great success in doing 1 full backup and a month worth of incrementals. Saves a TON of bandwidth and shortens backups considerably. I can backup a server with 4GB of data that changes infrequently in about 10Minutes via incrementals vs 3 Hours for a full over a 256Kb link. The vast majority of the time is search for and transfering the file list because the server has email which is so small. This server has nearly 1 million files which gives rsync a workout. I'd try excluding some large directories, make sure that the backups succeed and then slowly remove the excludes one by one and build up your full backup that way.

No, the only values for $Conf{XferMethod} for backups are smb, rsync,

Re: [BackupPC-users] notes on Seagate Free Agent drive
Chris Baker wrote: A couple days ago, someone asked about Linux and Western Digital external hard drives. This is a response, sort of. I am posting my notes on how I got a Seagate Free Agent drive to work with Linux. I hope this will help with other drives. I make no guarantees. We purchased a Seagate FreeAgent USB drive. Unfortunately, Seagate only supports it with Windows and Macs. It worked find with Windows XP. On the Linux box, that was a different story. Research indicated that the drive was already formatted into NTFS. I knew this would not be an issue as people mount NTFS partitions all the time on Linux. I went to the site www.linux-ntfs.org. I found just about all I needed on that site. I found this page especially helpful: www.linux-ntfs.org/doku.php?id=ntfsmount. It had some good instructions: First of all you need to download FUSE from Sourcefourge. Then: tar zxvf fuse-2.7.0.tar.gz cd fuse-2.7.0 ./configure Make make install Then you need to install ntfsprogs: tar zxvf ntfsprogs-2.0.0.tar.gz cd ntfsprogs-2.0.0 ./configure --enable-fuse-module Make make install This installed the ntfsmount command, which I did not have before. But I wasn't quite finished. Apparently the issue with this drive has to do with power management. I ran the command hdparm -Z to disable Seagate auto-powersaving mode. After that, I simply ran the command: ntfsmount /dev/sda1 /media/FreeAgent_Drive Then, I was ready to go. I could get to the hard drive through the GUI or the command line. Why didn't you just reformat it with your favorite filesystem?

Re: [BackupPC-users] free backup software
drew64 wrote: I have been looking for some free backup software to back up my music and photos to an external hard drive and maybe DVD's. I have tried Cobian but dont know if I like it since it has no restore function. Have read somethings about winbackup and was also told to try comodo backup. Any one have any experience with these. Also When I tried Cobian I set it to incremmental backup. It worked but I see it makes a new folder everytime a backup is made. Is there a way or a program that will just back up and replace the file that has changed into the same folder? I guess rsync would do it. It's like a copy tool that only transfers the changes and it can work both locally and over network connections. It is a command line tool though. I don't know what OS you're running, but there are also some rsync GUI frondends out there I believe. BackupPC also supports rsync as a backend, but it might be overkill for just backing up a single machine. Also take a look at rdiff-backup if you want to keep multiple versions of files. BackupPC also supports rsync as a backend, but setting up a BackupPC server for just one machine might be overkill maybe. It will work though and its web interface is very handy for restoring files.

I guess you didn't start the backuppc daemon. Try 'service backuppc

this server must have SE Linux turned on.
How to make this work, please?
I guess you'd need to ask the Fedora Project, but I don't think
they'll respond to bug reports about releases that reached end of life

Re: [BackupPC-users] Why should I use root to connect to host
brunal wrote:
One question that I dont understand : can I use another user than
root to connect to my host?
Indeed, the server i want to backup is the main server of my network,
and pretty well secured. That means, hence, that root cannot have
access to the server through ssh, only non-root user can.
Is this a problem? my config is in the hosts file :
192.168.1.20backuppc# --- example static IP host
entry
and in config.pl :
$Conf{RsyncClientCmd} = '$sshPath -v -x -l backuppc $host $rsyncPath -
v $argList+
And to my host side, a user backuppc exist and have access to all the
necessary folder and file. Should this configuration work?
Unitl now I still have other problem (see other post), but I would
like to check if I'm not doing something wrong.
See 'How can client access as root be avoided?' in the documentation:
http://backuppc.sourceforge.net/faq/ssh.html#how_can_client_access_as_root_be_avoided
The examples there use 'sudo' in $Conf{RsyncClientCmd}, but I believe
that doesn't work: you need to specify the full path to the sudo
binary (for instance: /usr/bin/sudo, check on your systems).
