Hi Valeri,
To go off on a tangent, do you use the Bareos community edition, or the paid
version?
I use open source - community edition. I work for the department of the
university, they do not have much money, thus pretty much everything I
set up for them is free as in free bear. I have to invest my time and
knowledge - and help of others - instead of paid support, and this way I
earn my salary ;-) Suits both myself and my employers.

Hi Leroy,
I think that in my case I could not use a tgz archive. I'm speaking about full
backups that reach 600/700GiB, compressing them and then rsync them could take
so much time that it will be useless.
unless you use tape (of that high capacity), it is advantageous to restrict
volume size to, say, 50GB. Then when you restore, search for specific files
will be faster. And it will help your backup volumes transfers as well.

Hi Valeri,
thank you for your suggestion.
Is bacula the right backup system when I need to replicate data offsite? There
are other backup solution that simplify this process?
Bacula is great enterprise level open source backup system. I switched to its
fork bareos at some point; I use bacula/bareos for at least a decade. And with
this your extra requirement I still would stay with bareos (or bacula).
If I were to have two sets of backup: on site and off site, I would just set up
separate bacula/bareos director and storage daemon(s) off site. Add to FDs
(file daemons) extra instances of director - offsite one with different
passwords for the sake of security. Then there will be a set of everything off
site, not only a set of volumes. Of course, if you only have a set of volumes,
but everything else has evaporated, you still will be able to restore
everything, including database records by scanning set of volumes. Which will
take forever. I would alternate dates of backups in offsite/onsite schedules,
or define times of backups so that they do not overlap.
Another good news of this vs just rsyncing volumes is: bacula/bareos verifies
checksum of every backed up file after receiving it. This will ensure
consistency of files in remote volumes, for rsync you will have to at least
verify checksum of each volume transferred to destination (unless I miss my
wits and rsync does verify checksums of files transferred, I just re-read rsync
man and don't see verification - hopefully rsync expert will chime in and
correct me if I'm wrong about rsync).
Anyway, that is what I would do.
Valeri
Thank you in advance
