I think my problem is similar. I have a Linux ("orion") running Samba.
A Win7 client uses it to store it's "Windows Backup". That's OK.
From another Linux ("saturn"), I do an rsync via an rsync-module,
and have already 4 Versions where the ".vhd" file of that Windows Backup
is destroyed on "saturn". So the corruption happens when starting
rsync @saturn, copying orion->saturn, both having XFS.
As I cannot delete the broken files, I moved the whole dir away,
and did an rsync again. The same file destroyed again on saturn.
Some days later, again 2 versions which are destroyed.
The difference to Linda is, I get:

Trying to "xfs_repair -n" seems to find errors, see attachment "repair1.log"
Trying to "xfs_repair" crashes, see attachment "repair2.log"
Saturns kernel is 2.6.31.12-0.2-desktop from openSUSE 11.2,
xfs_repair is 3.1.2 (I tried down several versions down to 3.0.1, all without
success).
Even after xfs_metadump and xfs_mdrestore the error exists, and cannot be
repaired with xfs_repair, because that crashes.
I've put a new metadump containing only the broken stuff for public review:
http://zmi.at/saturn_bigdata.metadump.only_broken.bz2 (197 MB)
What should I do, apart of ripping the whole filesystem and copying new?
The problem is, would be destroyed again, just like it did 4 times now.
