[Duplicity-talk] How to make snapshots

[Yannick Gingras]

Hi, 
  I'm currently using rsnapshot but I'm looking at moving my backups on
S3 so I'm considering a switch to duplicity.  One of the features that
I really like with rsnapshot is the space efficient snapshot
mechanism.  Is there an easy way to have that with duplicity?

What I mean is that rsnapshot gives me the following snapshots, each
hardlinked together:

daily.0
daily.1
daily.2
daily.3
daily.4
daily.5
daily.6

weekly.0
weekly.1
weekly.2
weekly.3

monthly.0
monthly.1
monthly.2
monthly.3
monthly.5

With that scheme, I can cover 6 months of time span on a decreasing
level of granularity with minimal disk usage: my 20GB backup set only
consumes ~40GB of disk space for those 6 months of archiving.
Restoring is as trivial as fetching a file with cp from one of the
snapshots.

The restore tests that I did with duplicity only gave me the latest
version of the files so it's not clear if it's possible to go back in
time.  Is it possible?
