Hi all,
I have two discs in RAID1 with three partitions on it:
hda1(c) - swap
hda2(c) - /
hda3(c) - /job
Why are you running swap on a raid device?
I will do some experiment with OS, so I should backup / partition (10GB). I have tape device that I big enough for backup of / partition purpose, but what will be the best way to do so?
I need backup for bare metal recovery of / partition.
No tape software backup will be suitable for bare metal backup/restore. There is no OS in a bare metal situation, so you have no way to restore.
Further, taking backups that are capable of being restored to a new raw disk usually entails taking the disk off line long enough to do it. You have to essentially do a partition dump, and you usually can't do that on a running partition.
Personally I never plan on doing bare metal retorations. I back up data and other critical configurations (such as email setups, etc) and plan on restoring the data to a freshly installed OS on the new box if that becomes necessary.

You DEFINITELY want to do this, otherwise, when 1 disk dies, so does your system if its using that swap!
