Ah, simply i put on tape the 'alpha.0' directory, the 'most recent backup'
in rsnapshot lingo.
It is marely a folder with all the file within.

Exactly what i need, indeed...

No, probably i've explained not well...

If the (file) pool have 3 media (files), ad the full is on the first media,
with some incremental scattered between other media/file, the virtual full
how 'pack' incremental in respect to media/files?

OK, so you are speaking of creating on the remote server, eg, a local storage
daemon to make a full backup to a local volume (on a USB disk, supposing)? Or,
eg, rsyncing the remote server to a local disk, connect tothe real storage
daemon and change temporarly the job definition to do an initial backup from
local content and not remote one?

How i can manage that in respect to volume names and file paths?!

The only solution that i see is to temporarrly move phisically the server
near the storage daemon and change temporarly the ip in the file daemon
definitition, do the initial full, and then return the server in place.

But clearly could be a bit problematic... ;-)
