Multiple identical backups with different names

[Philipp Riegger <lists@anderedomain.de>]

Hi,

is it possible to have multiple (identical) backups with different names?

Currently I have a backup script which creates backups with -daily-,
-weekly- and -monthly- in the name for every day, week or month
respectively. At the moment, those are completely different backups
created at different times from the same data.

Is it possible to create 2 backups with different names from the same
data at the same point in time without using snapshots or something like
this? From my point of view it should be very easy to implement this in
tarsnap (allow "tarsnap -c -f name1 -f name2 ...").

At the moment I can only think of something tarsnap-external like
snapshots (which would be more difficult to implement for me) or
something like "tarsnap -c -f name2 @@name1", but I think this would be
quite expensive, is that correct?

Any other suggestions/ideas?

Philipp
