[rdiff-backup-users] strangeness with a backup.

[Alan Horn]

Nightly backups started failing for a specific host.

Investigation shows that its failing at the check-destination-dir phase :

address@hidden fc-ps1]# rdiff-backup -l .
Fatal Error: Previous backup to /backup/fc-ps1/. seems to have
failed.Rerun rdiff-backup with --check-destination-dir option to
revertdirectory to state before unsuccessful session.
address@hidden fc-ps1]# rdiff-backup --check-destination-dir .
Warning, metadata file has entry for dev/audio,
but there are no associated files.

dev/audio doesn't exist in the backup tree. In the real server it's just a
symlink, and it hasn't changed since the system was installed a year ago.

Any ideas on how to fix this without losing incrementals history ?

Cheers,
