Re: [rdiff-backup-users] KeyError while backing up to sshfs

[Dominic Raferd]

Jochen:

what if you change /etc/backup.list by removing the final slash from /backup/dev/ i.e. /backup/dev

I think that with your backup list it tries to backup /backup/dev (though not its contents) and maybe this causes the failure?

Hi,

I get a (repeatable) KeyError while backing up to sshfs using 
rdiff-backup on linux (either version 1.2.8 or 1.3.3). My backups ran 
normally for about a year, then this error came, and they don't work 
since.

Any help would be greatly appreciated!

Regards,
Jochen

Command
===
rdiff-backup --no-hard-links --include-globbing-filelist 
/etc/backup.list --exclude-other-filesystems -v9 /backup /mnt/backup/one

Source directory /backup is a snapshot of /, /mnt/backup is a mounted 
sshfs, /dev does not exist in the target directory.

/etc/backup.list
===
- **/*~
- **/rdiff-backup.tmp.*
- **/#*#
- **/rdiff-backup.tmp.*
- /backup/usr/portage/
- /backup/tmp/
- /backup/var/tmp/
- /backup/sys/
- /backup/root/
- /backup/var/log/
- /backup/var/cache/
- /backup/var/run/
