[BackupPC-users] BackupPC Working Well - Except Archiving
I may have missed something obvious but I am unable to create an archive of existing backups using the CGI interface and schedule facilities. All other normal backups are successfully created this way. If started manually from the CGI interface the archive is created successfully. When scheduled via the CGI the Server log shows: 2008-11-17 08:00:00 Next wakeup is 2008-11-17 08:15:00 When scheduled via the CGI the Host log shows: Blank i.e. no entries Settings used for testing (have I missed others that are relevant?) BackupsDisable = 0 BlackoutPeriods = Deleted BackupZeroFilesIsFatal = Unticked The on-line documentation at Sourceforge mentions creating an archive at the command line using BackupPC_archiveStart. This method fails as the system cannot find BackupPC_archiveStart. Once archiving is operating as required the next step will be to incorporate ArchivePreUserCmd and ArchivePostUserCmd to enable the archive to be created on an external Truecrypt disk; however this stage will be tested separately and is mentioned for completeness only. Any and all suggestions on how to get this working will be welcomed.

Yes, the ubuntu install is different from the 'source' install, so the documentation doesn't fit exactly.

Re: [BackupPC-users] BackupPC Working Well - Except Archiving
Having read the Description within the files BackupPC_archive and BackupPC_archiveHost it appears that BackupPC_archive begins the archive creation process and then passes control to BackupPC_archiveHost which uses the settings listed in the CGI (ArchiveClientCmd). This implies that BackupPC_archive could become a cron job and thereby achieve the desired scheduling. Consequently, creating an archive occurs at a predictable date/time which might be beneficial taking into account the archive will take longer to complete than a normal full/incremental backup. Is this analysis correct? Adam Goryachev wrote: AFAIK, you don't schedule an archive... The scheduling only applies to full/incremental backups. Of course, I could be wrong... but that is my experience and understanding of the docs... I have only recently begun to explore the use of BackupPC and may be investigating areas which are better understood by more experienced users. In my view, if archiving is designed not to make use of the scheduling facility built into BackupPc, it is a little confusing for the CGI to present the same scheduling options as those available for full/incremental backups.

[BackupPC-users] Backuppc mirroring with rdiff-backup or not?
Hi everyone, i'm a backuppc user and i use it on several different linux servers, with backuppc backupping in some cases to internal hdd, raid or external hdds. I'd like to mirror the backuppc pool - I searched through ml archives and found that mirroring the backuppc pool (wherever it is) with rsync on an external hard drive isn't efficient and doesn't scale good - i've tried myself and is cpu and time consuming and very very long for big pools - not very reliable. So i've tried to mirror the pool with rdiff-backup, and it seems a little better, but not the optimal solution. In this ml the best solutions for this task are two hdd with pool on them (two external, or two in raid maybe) or dd form pool to external mirror disk - but NOT mirroring the backup with rsync or something like that - right? can you confirm that? And dd is time consuming like rsync but more reliable for backuppc pool?

[BackupPC-users] Keeping a specific full backup
Hi all I recently restored a crashed mac harddrive from a backuppc full backup (phew..). I'd like to keep that particular full backup (so if I later realize I actually needed some file I thought I didn't need in the original restore it's still there). Is there a way to change my current config.pl settings or individual [hostname].pl settings to not overwrite that particular backup (I'm using the default settings at the moment for how often and how many full incremental backups to keep)?

Yes. RAID1 and dd are equally good except that to use dd you must stop backuppc and unmount the filesystem dor the duration of the dd (with RAID1 you only need to unmount the FS just before you break the RAID to remove the external drive). And dd is time consuming like rsync but more reliable for backuppc pool? Generally dd and RAID1 will copy the entire pool in the time it takes to read the entire disk and write the entire disk. The problem with cp and rsync etc is that they need to read the filesystem structure, and make a huge number of small reads and small writes. Especially rsync needs to read the entire list of filenames and store them in memory before even starting to copy the data to the destination. This is what makes rsync a poor choice. Of course, I've not discussed if or how the changes in rsync v3 modify the above discussion, AFAIK, it is meant to solve or improve the situation by starting to copy the content before reading the entire file list, and also being less memory intensive while copying the data. Also, if your pool is only 10G of data, and your filesystem is 2TB, then rsync or cp will work better. The above discussion mostly applies to large pools. Although the definition of large pools is somewhat murky, and it differs depending on your backuppc hardware, I would guess something around 500G would be large...

Thank you so much, have a nice day Ermanno Hi, Yes use dd (or even better dd-rescue that is restartable and gives progress indication) for big pools. For smaller pools you might use cp -a or rsync -aH (restartable). You have to find out the practical upper limit for the latter methods depending on your requirements. Another alternative is to use at least three disks in a rotating scheme and RAID1. (Those of you who have been reading the list for more than a few days are getting tired of hearing this by now, I imagine...!) Say you have three disks labeled 1, 2 and 3. Then you would rotate them according to the schedule below, which guarantees that: - there is always at least one disk in the BackupPC server. - there is always at least one disk in the off-site storage. - all disks are never at the same location. 1 2 3 (a = attached, o = off-site) a o o a a o - RAID sync o a o o a a - RAID sync o o a a o a - RAID sync . . . On top of the RAID1 I recommend that you use LVM even though it might not be strictly necessary right now if your backups fit on one disk. The reason for doing that is when your disk are too small you can expand by using an second set of disks in a similar setup and add that second RAID1 to the volume.

Re: [BackupPC-users] Backuppc mirroring with rdiff-backup or not?
Also, if your pool is only 10G of data, and your filesystem is 2TB, then rsync or cp will work better. The above discussion mostly applies to large pools. Although the definition of large pools is somewhat murky, and it differs depending on your backuppc hardware, I would guess something around 500G would be large... I've tested rsync and rdiff-backup (http://www.nongnu.org/rdiff-backup/) and rdiff-backup seems to be more responsive, and seems to begin to write before rsync... anyone here with experience with rdiff-backup? I think that (except being -maybe- less time consuming) it's like rsync (good bads included) And thanks for your reply, Ermanno - 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/

Yes use dd (or even better dd-rescue that is restartable and gives progress indication) for big pools. For smaller pools you might use cp -a or rsync -aH (restartable). You have to find out the practical upper limit for the latter methods depending on your requirements.

(Those of you who have been reading the list for more than a few days are getting tired of hearing this by now, I imagine...!) Say you have three disks labeled 1, 2 and 3. Then you would rotate them according to the schedule below, which guarantees that: - there is always at least one disk in the BackupPC server. - there is always at least one disk in the off-site storage. - all disks are never at the same location. 1 2 3 (a = attached, o = off-site) a o o a a o - RAID sync o a o o a a - RAID sync o o a a o a - RAID sync . . . i'll try this too, where i have a raid or i need it thanks!

Re: [BackupPC-users] Backuppc mirroring with rdiff-backup or not?
I use rsync v3 on a pool of about 280GB and about a few million files. With rsync v3, the writes start within a few seconds of starting the sync and it traverses the entire pool in 10-20 minutes. I only transfer about 3-4GB of files each night with rsync reducing that to about 1GB over a T1 at 196KB/s in about 1.5-2 hours. Considering the transfer itself is going to take 90 minutes just by bandwidth restrictions, this is not bad. I used to run this on rsync 2.x but it took at least 3 hours to complete as the initial file list would take ages and ages. I also began push memory off to swap to make room for rsync which ground system performance to a halt. I think that you can use rsync v3 (on both sides) to sync pools without issue. I'm assuming that you are using linux here also. With *solaris you have the zfs option as well. I did some research a while back to use a cluster filesystem for the storage pool but all cluster filesystems have much lower I/O performance than an on-disk filesystem. Also, I did try to do some software raid mirroring over iscsi but did not do much more that basic testing. The problem here is that the raid mirroring is syncronous so the slow iscsi connection will effect backup performance quite a bit. I couldnt find any info on making the linux software raid work in async mode with the local drive being the priority drive. Unfortunately ZFS only does 2 redundant device raid workalike and you would want more redundancy to make this work. If you could do raidz* with any number of redundant drives you could also put local disk cache and log drives in place and let zfs handle the slow link on iscsi. local | remote disk1 disk2 disk3 |disk4 disk5 disk6 disk7=log,disk8=cache | On Mon, Nov 17, 2008 at 4:26 PM, Ermanno Novali [EMAIL PROTECTED]wrote: Yes use dd (or even better dd-rescue that is restartable and gives progress indication) for big pools.

Is the following true: 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. 2. If not, can I safely erase any (empty) attrib file that has no files associated with it? 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? Because, I have found some attrib files on my system in past backups that have file entries with type 0 (i.e *not* type 10) yet there is no file present in the directory. 4. If not, can I safely *remove* any non type=10 attrib entry if the corresponding file is not in the directory?

Re: [BackupPC-users] XP Client - samba vs rsync
smb is not ideal accross any sort of WAN or slow link.. smb is very much a LAN filesystem layer.. rsync is very functional, even on vista. You can create a user specifically to run rsync and give them read access to the directories you want to backup. Some people do have problems with rsync on windows but I have setup many machines with various windows from 2000 to vista sp2 and never ever had an issue.

[BackupPC-users] (Improved) Routine to delete individual files from selected backups...
I have vastly improved and completely rewritten my program
BackupPC_deleteFiles.pl. Also many bugs were fixed ;)
The routine now allows you to delete arbitrary files and directories
(or list or globs thereof) across multiple hosts and shares, and
arbitrary (contiguous) backup ranges.
Specifically, you can now delete files from either a single backup or
from a range of backups. The program then appropriately deletes and/or
moves files and attributes and correspondingly adds or removes type=10 delete
attributes so as to make sure that the files show as fully deleted from the
backup range while not affecting the files visible from subsequent
backups that were not deleted.
The only thing it can't do (and refuses to do) is to delete files that
are hard links or directories that contain hard links since I couldn't
find any easy way to find and keep track of hard links.
The program provides lots of (optional) verbosity and debugging levels
so you can be sure you are deleting what you want to (and from a
debugging perspective that the appropriate visibility and inheritance
rules are being faithfully applied).
Since the program is now 1000+ lines long, I won't post it, but I will
be happy to email it to anyone interested or post it if there is
enough demand. Instead I will just copy over the logic so people can
check it if they are so inclined (note it took me multiple attempts
before I truly understood the topology of the backup chains and how to
efficiently and accurately encode it).
I will also include a copy of the usage message and options:
usage: $0 [options] files/directories...
NOTE: if -s option not set, then file/directory names include the share name
Required options:
-h host Host (or - for all) from which path is offset
-n backRangeRange of successive backup numbers to delete.
N delete files from backup N (only)
M-N delete files from backups M-N (inclusive)
-M delete files from all backups up to M (inclusive)
M- delete files from all backups up from M (inlusive)
- delete files from ALL backups
Optional options:
-s shareNameShare name (or - for all) from which path is offset
(don\'t include the 'f' mangle)
-l Just list backups by host (with level noted in parentheses)
-r Allow directories to be removed too
-H Skip over hard links (otherwise exits without deletions if
hard links found)
-m Paths are unmangled (i.e. apply mangle to paths)
-q Don\'t show deletions
-t Trial run -- do everything but deletions
-c Clean up pool - schedule BackupPC_nightly to run (requires
server running)
Only runs if files were deleted
-d levelTurn on debug level
Program logic is as follows:
1. First construct a hash of hashes of 3 arrays and 2 hashes that
encapsulates the structure of the full and incremental backups
for each host. This hash is called:
%backupsHoHA{hostname}{key}
where the keys are: ante, post, baks, level, vislvl
with the first 3 keys having arrays as values and the final 2
keys having hashes as values. This pre-step is done since this
same structure can be re-used when deleting multiple files and
dirs (with potential wilcards) across multiple shares, backups,
and hosts. The component arrays and hashes are constructed as
folows:
- Start by constructing the simple hash %LevelH whose keys map
backup numbers to incremental backup levels based on the
information in the corresponding backupInfo file.
- Then, for each host selected, determine the list (@Baks) of
individual backups from which files are to be deleted based on
bakRange and the actual existing backups.
- Based on this list determine the list of direct antecedent
backups (@Ante) that have strictly increasing backup levels
starting with the previous level 0 backup. This list thus
begins with the previous level zero backup and ends with the
last backup before @Baks that has a lower incremental level.
Note: this list may be empty if @Baks starts with a full (level
0) backup. Note: there is at most one (and should in general be
exactly one) incremental backup per level in this list starting
with level 0.
- Similarly, constuct the list of direct descendants (@Post) of
the elements of @Baks that have strictly decreasing backup
levels starting with the first incremental backup after @Baks
and continuing until we reach a backup whose level is less than
or equal to the level of the lowest incremental backup in @Baks
