Hi everyone,
we are using rdiff-backup for quite a while now, but two weeks ago, it stopped working. One part of our backup strategy is backing up everything onto another local disc.
The source is a disk with xfs-filesystem, destination is ext3, we have specified the --never-drop-acls option set, and this is, where our backup currently exits (though we have successfully used that option in the past). More information on my setup is included below.
I'd be happy for any assistance, as i am currently not able to solve this problem on my own. 

Best wishes
Claudius


The machine in question runs Ubuntu Server 8.04LTS and rdiff-backup 1.2.2

The pylibacl and python-pyxattr packages are installed.
These are the mounted volumes (output of mount in the console, upper one is source, lower one is destination) /dev/mapper/space_vg-space--r5 on /mnt/space-r5 type xfs (rw,noatime,nodiratime,nobarrier,logbufs=8) /dev/mapper/bakAutomat2_vg-bak02 on /mnt/bakAutomat type ext3 (rw,noatime,nodiratime,acl) 

Here's my full console-output:
