Hi,
Thank you for a great reply! The disks will most likely reside inside a
cabinet, and some of the full backups will probably be stored on tape
too. I have seen that you can choose to "export" files from one backup
archive to a zip file, and if you do so i guess you can just unzip it
and do a manual restore of the files?
So one thought that i have had is to write zip files to tape, since then
we can restore from tape without a working installation of BackupPC.
Would it be possible to create a script that uses BackupPC_ZipCreate to
dump backups and then write them to tape? Is there any documentation on
how to call BackupPC_ZipCreate? I guess that it can be pretty tricky to
specifiy which files to dump from the correct backup set. Is there any
documentation on how to use the BackupPC_* commands?

I sent an e-mail to the list last week and got good answers so
now i have tested BackupPC for a short time, the result has been
satisfying. But as always some new questions has poped up. Lets presume
that the server that runs BackupPC and stores all backed up data
crashes. The system disk is unusable but the data disks seem to be fine.
At the same time I need to restore several backups from the data disk,
what is the fastest and easiest way to get my backed up data back? Doing
a manual restore is no problem if its possible to access the backed up
data without BackupPC.
At least a few on this list have attested to leaving the data disks in
an external case so it can be switched to another machine with the same
version of BackupPC installed, presumably with a cron job rsync'ing the
program directory every night. Others have described using a RAID with
mirroring, so you always have a backup drive available in the event of
failures. If those drives are in a removable chassis, you could
occasionally pull the drive and insert a new one, forcing a re-sync and
giving you a backup that you can carry off to a safe storage location,
in the event of a total meltdown or break-in. Still others lay off the
data to tape in a non-backup-pc form from the most recent full backup.
I think it really depends on your level of comfort with technology, your
budget, and your anticipated level of direct involvement.
Is there any compability problems with backups from different
versions of BackupPC?
I believe, though I haven't tried it, you can restore files from an
older version. You will have more problems if you decide to switch
transport layer protocols, though, because the way certain kinds of
links are stored in the pools differs. I don't know the details, but if
you search the archives, you will find more answers.
