[rdiff-backup-users] Failed backup question

[Martin Fisher]

Hi All

I have an rdiff-backup to an external usb drive running on the half hour
from cron, viz:

30 * * * * rdiff-backup --include /home/martin/Desktop
--include /home/martin/Documents --include /home/martin/Music
--include /home/martin/Pictures --include /home/martin/.tomboy --exclude
'**' /home/martin /media/ext3backup2/rdiff-backup

It just failed, probably because the computer was turned off whilst it
was underway. It did not run again at the next half-hour, when the
computer was on, and when I ran

rdiff-backup -l /media/ext3backup2/rdiff-backup

I received this:

Fatal Error: Previous backup to /media/ext3backup2/rdiff-backup seems to
have failed.
Rerun rdiff-backup with --check-destination-dir option to revert
directory to state before unsuccessful session.

According to the manual:

--check-destination-dir
If an rdiff-backup session fails, running rdiff-backup with this option
on the destination dir will undo the failed directory. This happens
automatically if you attempt to back up to a directory and the last
backup failed.

This didn't seem to happen so I ran the backup directly from the command
line, and this the output appears below. I don't understand what it is
telling me. Could anybody help by enlightening me?

With thanks, Martin

Previous backup seems to have failed, regressing destination now.
