Backup Management: Combine Snapshots

Registered by Rob Oakes on 2009-09-25

A major problem with the existing Time Drive/Duplicity implementation is that there is no easy way to manage long backup chains without manually restarting the backup job. In comparison, Time Machine for Mac OS X has the ability to retroactively purge backup sets in order to simplify the number of backup snapshots. Time Drive should contain a similar feature.

Specific Aims:

* Be able to combine snapshots from a specified time range (say the past week or month) into a single snapshot.
* If the file has changed multiple times in that period, the most recent diffs should be kept and older diffs thrown out. Consolidates and decreases the overall backup size.
