Re: [Duplicity-talk] duplicity 0.4.3.RC12 failure on full backup

[Kenneth Loafman]

A couple of things to look for:

- make sure there is plenty of room on the target system.
- make sure to exclude /proc from the backup.  <<<--- Important!

The --full and --cleanup cannot be used together.  I need to separate
things like that out as 'action' versus 'option' parameters and flag an
error if two actions are used together.  Been low priority so far.

Use --cleanup --force to actually delete the incomplete sets.

If all this fails, turn on -v9 and send me the result.  It may be fairly
verbose, so you might want to zip it first.

...Thanks,
