Are the link errors all coming from files with characters that
aren't 7-bit ASCII? Maybe this is a perl character set issue.
On the same server we have 8 others backuped machine with perhaps some
filename with 8-bit chars (ISO-8859-1) without problems but only one dir
/home 13Gb size. We tried with tar, rsync, rsyncd, with the same result,
and we have 56Gb left on the LVM2 device.
Last thing, we noticed this problem after added some big files on this
dir, no too much problems before...
Hm, I have a suspicion that backuppc somehow or somewhere doesn't play
nice with big files, even with huge timeout settings. Where 'big' is
larger than about 400 MB. I only use rsync-over-ssh or rsyncd, so I
don't know if this is backuppc related or rsync related.
I have not bigs file but big directories size 4Gb and 13Gb
What you can try is see if regular rsync does work. You'll probably need
to install an rsync daemon on your backuppc server, but that shouldn't
interfere. Then execute the same command as backuppc does to try and
backup the problematic directory. If that does work, that it isn't any
charset issue, but more likely something in backuppc (bug in rsyncp,
backuppc itself or your config). In that case, I still think you should
collect as much debug info as possible (output from tcpdump, strace and
logfiles from backuppc) and report back to this list or to Craig Barratt
personally. Maybe he or we can then see what's going on.
I make tests with rsyncd *out* of BackupPC on the same LVM2 device with
the command:
rsync -av --numeric-ids --perms --owner --group --devices --links
--times --block-size=2048 --recursive --exclude Maildir/
[EMAIL PROTECTED]::MyModule ./temp
With 2 directories, one 4Gb, one 13Gb the rsyncd failed on some files,
sometime .psd, sometime .dll and if I try to restart the backup it stop
on the same file. If I remove the file from the remote directory and
restart the backup it continue the process for a variable set of time
and failed with an other file...
The remote machine is on ADSL 1Mbps upload, when the rsync backup failed
I got the message:

It seems that it's not a BackupPC problem but rsync or dsl link...
Some help is welcome :-/
