John,
We do that here (Backup to disk and then to tape). We have just started
using Bacula but we us it to backup to tape. I use Microlite's
BackupEDGE to backup my remote Servers to disk on my main backup server.
I have a network that is only used by me over night so differentials at
night are a piece of cake. We have a long time invested in BackupEDGE on
our SCO Servers. Then during the day I use Bacula to backup my Server
that holds the nightly backups. This works fine for us. I am not a
Bacula Guru but I think it would be just a matter of setting up
different jobs at the right interval to do what you want.
As for restores here we would first look to the on disk differentials
to see if the required file is there. In case of a disaster here I would
have to make a site visit to rebuild things so I would have a tape on
site of the Master, then once the system is back online I would just
restore the last differential. If I had to go to a previous volume that
was no longer on Disk I would locate that volume in the tape library and
restore that volume to disk and then restore that to my system. Before
we went to this we only kept the last thirty days of data anyway so this
provides us a longer recovery trail. I have had users delete something
and then ask me 45 days later if I still have the file. But in those
cases it was usually just a report format that could be recreated in
less time than it takes to restore the file.

Hi all,
I work in a ICT company and we are looking to replace Amanda. I figured
Bacula would be te best solution, but we hit a snag.
A feature my boss feels is paramount to a back-up package is write the
data to disk, then to tape. Bacula does that in a way, but "data
spooling" does only that; spooling. I need it to write to disk, then
copy or migrate the data to tape. According to the documentation, that
is a feature planned for the future. Unfortunately, I need it now.
I've considered simply backing data up to disk volumes, then copy that
to tape by other means, but I'm puzzled how a restore would work in
that
sort of situation.
Is there a workaround someone has successfully used in the field, on
production servers? Hating to have to reinvent a proverbial wheel, I
figured I'd ask the community. I really love Bacula and I would love to
use it in stead of giving Amanda a version bump and a fresh install on
our shiny new backup server.
So in short; I want backups on disk, then copy them to tape (with
Bacula, other backup software, commandline script, whatever). We run a
schedule much like the one explained in the manual ("a daily, weekly,
monthly tape usage example").
Thanks in advance!
