I'm also experiencing this bug. I'm backing up to RackSpace via DéjàDup.
I don't know if this helps any, but I have DéjàDup configured to backup
daily and keep backups for "at least a month." Because my backup set is
large and my machine isn't always online, full backups take considerably
more than a week to complete, meaning that once a full backup completes,
it's only a few days until DéjàDup decides to do another full backup.
Additionally, when restoring, I only have two restore points available:
2011-07-01 and 2011-07-14 (today's date is 2011-08-11, and backups
should be happening daily).
Finally, the backup that ran today aborted with an error. However,
unfortunately I didn't note the error, since I wasn't in bug-reporting
mode.
I don't know whether any of this info is helpful in diagnosing this
problem.
