Package: duplicity Version: 3.0.5.1-2 This just happened again, with the most up-to-date version.
To reiterate, the situation is: - full backup (successful) - incremental backup (successful) - ... - incremental backup (successful) - full backup (incomplete, failed, ran out of space) - duplicity remove-all-but-n-full 1 --force ... At this point, *EVERYTHING* is deleted. Maybe this should be raised in severity?
