[Duplicity-talk] feature req: differential vs incremental

[Travis H.]

I learned something new about backups the other day.
I'm not sure if other people know it.
Basically, a differential backup is taken relative to the
last full backup, whereas an incremental backup is taken
relative to the last incremental backup.

So if restore time is more important to minimize than disk space,
differential means you'll just restore two archives, the full and
the differential, regardless of how many times you've done differential
backups.  So it sort of splits the middle between "always full
backups" and "full then many incremental backups".
