Re: [BackupPC-users] 38GB file backup is hanging backuppc (more info and more questions)
Hi!
I had this trouble some time ago while backing up vmware virtual machines (the
files were extremely large about 120GB) and rsync would behave just like you
are saying it happens to you. I had other smaller vms about 10 GB and those
worked perfectly with rsync.
I did some research and from what i've found the clues were going to the rsync
protocol itself while transferring large files.
I changed the transference mode from rsync to tar and since then I had no
trouble.
Cheers
Pedro

Now because of another comment, I tried to disable the use of RStmp
and force BackupPC to do the equivalent of the --whole-file where it
just copies the file across without applying the rsync
differential/incremental algorithm. I executed a full backup after
moving the file in the prior backup aside. So I moved
/backup-pc/pc/ldap01.bos1.renesys.com/326/f%2fdata%2fbak/ffedora-ds/fcurrent/fuserRoot/fid2entry.db4
to
/backup-pc/pc/ldap01.bos1.renesys.com/326/f%2fdata%2fbak/ffedora-ds/fcurrent/fuserRoot/fid2entry.db4.orig
I claim this should make rsync diff against a non-existent file and
thus just copy the entire file, but I still see in the lsof output for
the BackupPC process:
BackupPC_ 18683 backup8u REG9,2 36878598144 48203250
/backup-pc/pc/ldap01.bos1.renesys.com/new/f%2fdata%2fbak/RStmp
and there is only 1 file that is that large (36878598144 bytes) under
that volume and it is the id2entry.db4 file.
So what did I miss?
Does BackupPC search more than the prior backup? I verified that run
327 (which is the partial copy) doesn't have any copy of:
f%2fdata%2fbak/ffedora-ds/fcurrent/fuserRoot/fid2entry.db4
in it's tree. So where is the RStmp file coming from?
At this point it's been running about 24 hours and it has transferred
only 10GB of the 30GB file.
This is ridiculously slow. If my math is right, I should expect a
36GByte file at a 1Mbit/sec rate (which is about what cacti is showing
as a steady state throughput on the ethernet port) to transfer in:
'36*1024*8/(3600*24)'= ~3.413
so it will take 3 and a half days at this rate. This is with both
systems having a lot of idle time and 1% wait state.
If I run an rsync on the BackupPC server to copy the file from the
same client, I get something closer to 10MBytes/second
(80Mbits/sec). Which provides a full copy in a bit over an hour.
Also one other thing that I noticed, BackupPC in it's
$Conf{RsyncArgs} setting uses:
'--block-size=2048',
which is described in the rsync man page as:
-B, --block-size=BLOCKSIZE
This forces the block size used in the rsync algorithm to a
fixed value. It is normally selected based on the size of
each file being updated. See the technical report for
details.
is it possible to increase this or will the Perl rsync library break??
It would be preferable to not specify it at all allowing the remote
rsync to set the block size based on the file size.
I see this in lib/BackupPC/Xfer/RsyncFileIO.pm:
sub csumStart
{
my($fio, $f, $needMD4, $defBlkSize, $phase) = @_;
$defBlkSize ||= $fio-{blockSize};
which makes it looks like it can handle a different blocksize, but
this could be totally unrelated.
I could easily see a 2k block size slowing down the transfer of a
large file if each block has to be summed.
Anybody with any ideas?

[BackupPC-users] Looking for BackupPC_compress to install a file manually in a backup
Hi all: Still trying to get a single master copy of the problematic db4 file into backuppc's cpool. I thought I could copy it over manually, put it in the right place in the partially completed backup tree and start a normal full backup. I can easily copy the file in 15 minutes or so (at 35MB/s), but I can't do the compression that the files in the backup tree use. IIRC BackupPC's compression mechanism isn't just a gzip of the file. There is a BackupPC_zcat, but there is no BackupPC_compress. Does anybody have such a beast, or is it impossible to create such a program becuase info is needed from the transfer protocol (rsync) to make the copressed version of the file? -- -- rouilj John Rouillard System Administrator Renesys Corporation 603-244-9084 (cell) 603-643-9300 x 111 -- Create and Deploy Rich Internet Apps outside the browser with Adobe(R)AIR(TM) software.

1) Aborting backup up after signal ALRM
The backup is taking longer than your $Conf{ClientTimeout}
setting. Once you hit $Conf{ClientTimeout} seconds a sigalarm is sent
to the process, which causes it to exit.
2) Backup aborted (Child exited prematurely)
Could be a number of things. IIRC this also shows up when it fails
during the initial startup. If you also see a message similar to
can't transfer 4 bytes and you are using the ssh transport mechanism
there is something causing bogus output in the .login or other startup
files for the shell (or ssh config files).
3) Aborting backup up after signal INT
Usully I see this when I stop the backup using the web interface.
4) Aborting backup up after signal PIPE
I see this as well, not sure what the cause is. Something failed in
the interprocess communication between the processes backuppc spawns.
What failed who knows.

[BackupPC-users] Revamping the Wiki
Hello everyone, I've been looking over the BackupPC wiki to find somewhere to integrate my own material, but it's in pretty bad shape. There's no consistent structure or formatting, and I remember from my initial experience with it that everything was very hard to find. There is a proposed structure page (http://backuppc.wiki.sourceforge.net/ProposedWikiStructure) but it is fairly old, has no discussion, and it's suggestions are only partially implemented. I'd be willing to do a lot of the cleaning myself, though I don't want to step on anyone's toes without talking with you first. Also, my knowledge of BackupPC is fairly limited to my setup (XP/Vista clients Ubuntu server). Who would be interested in a short meeting about this, say this Sunday at 12pm via Skype or IRC? My username for both is edallme. Also, please send any other suggestions you have to me or add them to the ProposedWikiStructure wiki page/discussion.

Re: [BackupPC-users] When will backuppc begin pooling?
Thank you so much for your very informative response. When I run the command: perldoc IO::Dirent, i get No documentation found for IO::Dirent so it seems it is not installed?

If you get something like... No documentation found for IO::Dirent. ...your problem probably lies elsewhere.

Re: [BackupPC-users] When will backuppc begin pooling?
yes. it is different than the install directory. I configured backuppc to use my RAID 6 array to store the backups, not the system drive. The full and incremental backups work fine.

Re: [BackupPC-users] When will backuppc begin pooling?
That's unfortunate. I can't just mount my array there as it is basically my NAS that use to store all of my media. It sounds like I will have to go without pooling if I want to back up to another location other than /var/lib/backuppc thanks to everyone who responded On Thu, Feb 12, 2009 at 7:43 PM, Adam Goryachev mailingli...@websitemanagers.com.au wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Brian Woodworth wrote: yes. it is different than the install directory.

Correct, because this is not a supported method of changing the location for backups. You should revert (undo) the changes you made so that the pool is configured for the default /var/lib/backuppc and then mount your raid 6 array at /var/lib/backuppc. This will solve the problems you are having, and from your next backup, pooling will start to be used.

RStmp is a temporary file used to store the uncompressed pool file, which is needed for the rsync algorithm. It's only used for larger files - smaller files are uncompressed in memory. RStmp is independent of --whole-file.

It sounds like I will have to go without pooling if I want to back up to another location other than /var/lib/backuppc Actually, not quite, any of the following should work: 1) mkdir /media/backups;chown backuppc.backuppc /media/backups;mv /var/lib/backuppc/* /media/backups/;ln -s /media/backups /var/lib/backuppc This will put the pool, pc, etc dirs onto /media/backups, and then symlink /var/lib/backuppc to /media/backups. This should work, without needing to modify TopDir/etc... put them all back as they were. Just be careful when upgrading the package it doesn't remove the symlink in the future. 2) http://linux.die.net/man/8/mount [quote] Since Linux 2.4.0 it is possible to remount part of the file hierarchy somewhere else. The call is mount --bind olddir newdir In your case: mount --bind /media/backups /var/lib/backuppc I'm sure there are other methods as well, just search the mailing list, the wiki, etc for TopDir Hope that helps.
