[rdiff-backup-users] --just-fix-my-broken-backup ?

[Adam Lazur]

The filesystem I've been backing up to has suffered some filesystem
damage. I've fsck'd and it assures me everything is better now that
there are 1365 files in lost+found.

So I let rdiff-backup get back to its regularly scheduled backups, but
it bails every time like so:

rdiff-backup --remote-schema "ssh -c blowfish -i $host/sshkey -C %s 
rdiff-backup --server" --print-statistics --include-globbing-filelist 
ninjak/1-includes --exclude-globbing-filelist ninjak/5-excludes 
address@hidden::/ ninjak/mirror
Previous backup seems to have failed, regressing destination now.
Warning, metadata file has entry for 
home/rave/Maildir/cur/11069ssio2222229e/Maildir/cur/1103912295.17181_0.ninjak.clustermonkey.o6
 ModTime 1103748io22222id 1003,
but there are no associated files.

Is it time to perform surgery on the metadata file? I'm cool with
blowing away portions of the tree to save my backup... but I'd rather
not pull the whole tree over my home dsl if I could avoid it.
