Hi

A quick look at you debug has an 'join acl' in it....

I am no expert or have fully read all your debug but....

putting --no-acls in the command line fixed all my problems and they allwork perfectly now.

it might be worth a try until someone who really knows gives a moreanalytical result ;-)

I'm writing because I need help getting my rdiff-backup process to
work reliably. I use rdiff-backup with cron, twice a day to snapshot
the entire ext3 rootfs of a desktop to an ext4 FS sitting atop
dmcrypt, iscsi, lvm, and raid.  The full command I use is.
rdiff-backup \
                --exclude-other-filesystems \
                --print-statistics \
                --verbosity 2 \
                --exclude-device-files \
                --exclude '/home/*/.gvfs' \
                --exclude '/home/*/.gtk-bookmarks/.gvfs' \
                --exclude '/home/*/.gtk-bookmarks' \
                --exclude '/home/*/.kde/share/apps/ktorrent/log' \
                --exclude '/tmp' \
                --exclude /var/lib/mysql/mysql.sock \
                / /mnt/iscsi-pataraid-lun-1/rdiffs/Zero-rootfs

That worked fine for a good month or so.  Then out of nowhere, backups
started failing.  It appears something "happened" to the destination's
rdiff structure sanity.  I'm pretty sure it's the destination's fault,
because if I make a new destination on another filesystem or even
another directory on the same one, the problem goes away... for a
while.  All of the --excludes I use are to reduce the 'noise' I was
getting otherwise over various file locks or files disappearing during
backup.  I'm curious how other users deal with gvfs.  I was originally
hoping --exclude-other-filesystems would take care of gvfs but it
appears otherwise.  Here's the actual error I get.  Twice a day now in
email.  Thanks Cron....

Previous backup seems to have failed, regressing destination now.

I just tried "rm /home/bcrook/.gstreamer-0.10/ -rf" in the off chance
that would make some difference.  It did not.  So I re ran the same
comand with strace, and here's the last little bit of its 415MB
strace.  It starts just before the rdiff-backup process bursts in to
flames.
