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?
