Hi,

If the backup target fills up, there's no way to recover.
--check-destination-dir and --remove-older-than both just
complain about lack of space.

Is there a workaround for converting full rdiff-backup volumes into one
that --check-destination-dir or --remove-older-than can be run on?

# df -h
[...]
/dev/hda1 236M 236M 0 100% /boot
[...]
sid:/boot# rdiff-backup --remove-older-than now /boot/backup/
Fatal Error: Could not open rdiff-backup directory

/boot/backup/rdiff-backup-data

due to

[Errno 28] No space left on device:
'/boot/backup/rdiff-backup-data/rdiff-backup.tmp.0'

which means you're blocked, forced to manyally do some removals. Do you
consider rdiff-backup should clean the mess or has the user to deal with
it manually ?

Bye,

I'm very new to rdiff-backup, so take my advice with a grain of salt,
but maybe it doesn't need a *lot* of space..
Maybe you could move all the session_statistics*.data and
file_statistics.data.gz files out of the rdiff-backup-data directory
temporarily and then have enough space to --remove-older-than.

Yes, that's what I meant by "manually do some removals" but I think it
could be interesting if rdiff-backup could manage this situation by
itself, not relying on me Smile

That would be pretty cool, but it seems to me a pretty difficult
challenge. You have the power and knowledge to back up those files
somewhere safe, but rdiff-backup wouldn't know where it could put them
other than just deleting them.
