I'm encountering a strange rdiff-backup error when using a remote source
and a remote destination, but seemingly *NOT* on an initial backup (no
rdiff-backup-data directory in the destination), only on subsequent backups.
Looking through the archives for this list, there are a couple of
threads that seem related:
http://lists.gnu.org/archive/html/rdiff-backup-users/2006-06/msg00041.html
http://lists.gnu.org/archive/html/rdiff-backup-users/2004-12/msg00049.html
Here's a typical error trace (from the destination's backup.log):
Sending back exception CCPP index out of order: ('backup', 'hosts',
'backup', 'rdiff', 'etc', 'ssl', 'openssl.cnf') ('backup', 'hosts',
'fog', 'rdiff', 'etc', 'SlimServer_v6.3.0', 'CPAN', 'arch', '5.8',
'mipsel-linux', 'auto', 'DBD') of type exceptions.AssertionError:

File "/usr/lib/python2.4/site-packages/rdiff_backup/backup.py", line

assert index >= self.cache_indicies[0], \
That trace resulted from running the following:
rdiff-backup -v5 --print-statistics [EMAIL PROTECTED]::/raid/home
[EMAIL PROTECTED]::/raid/backup/home
I.e. I'm trying to backup a large dir tree (home) from one server to a
dir on the same server, issuing the command from a separate server. I'm
issuing the command as user 'backup' - the same user as the destination,
and *NOT* as root (the source user). Interestingly, I can issue a
similar command, using different (smaller) directories, and it seems to
work reliably.
If I switch to the backup server and run the following command locally,
it works fine (even recovering from the previous failed attempt):
rdiff-backup -v5 --print-statistics [EMAIL PROTECTED]::/raid/home
/raid/backup/home
The files and paths referred to in the first line of the error trace
aren't consistent (i.e. it doesn't fail consistently at the same place).
As mentioned in the first thread listed above, I checked /tmp on both
the source and destination machines, and there are *no* rdiff related
files (that I can find).
I'm using rdiff-backup v1.0.4 on both machines. Normally, I'd just
update to the most recent version (stable or unstable) and see if the
problem goes away -- but since both previous references of the (same?)
problem are from versions prior to v1.0.4, I thought I'd run it past you
guys first.
Any insight would be greatly appreciated. I'll be happy to provide
additional details that might shed light on the problem.
Thanks!
