Backup Central

I have tried to use rdiff to back up my laptop to an SMB share (on a
Buffalo Linkstation NAS) using this command:

rdiff-backup /home/matt /mnt/linkstation/mnt1

It fails with this error:

File "/usr/lib/python2.4/site-packages/rdiff_backup/fs_abilities.py",
line 245, in supports_unusual_chars
assert not rp.lstat()

I have no problems running rdiff to a plain local directory like this:

rdiff-backup /home/matt/test1 /home/matt/test2

I am using rdiff version 1.0.1 from the FC4 rpm. Does rdiff not work in
this manner?


Thanks,
Matt

I don't think it works in this manner yet - we are working on it.
Can you try the delevelopment version? It does some extra things that
might help SMBFS, CIFS and windows in general

Ok. I installed the latest release. Now I get this:


rdiff-backup --exclude /home/matt/.ccache --exclude
/home/matt/.thunderbird --exclude /home/matt/tools /home/matt/

Any ideas?

Thanks for your help,

Hmm, both of these problems (with v1.0.1 and the devel version) where
raised in the sanity-checking part, where rdiff-backup is examining
the basic properties of your file system.

Ok. I installed the latest release. Now I get this:


rdiff-backup --exclude /home/matt/.ccache --exclude
/home/matt/.thunderbird --exclude /home/matt/tools /home/matt/
/mnt/linkstation/mnt1/test/
...
os.rmdir(path)
OSError: [Errno 16] Device or resource busy:
'/mnt/linkstation/mnt1/test/rdiff-backup-data/rdiff-backup.tmp.5'

Hmm, is anything in that directory? Anyone know what could cause this
error on an SMB filesystem?

If the problem is just that random basic directory delete operations
don't work on your filesystem, then I don't think there is much hope
for rdiff-backup.
