Hi folks,
I have a question about backups.
I have a RedHat 7.1 system using Software RAID-1 filesystems.
QUESTION: What is the best method of performing backups of the root
filesystem? I want something that will give me a perfect copy that
could be restored.
Option 1:
Normally, I would use my PowerQuest DriveImage software (similar to
Norton Ghost), but the problem is, it doesn't recognize the RAID
partitions (it knows Linux ext2 though).
Option 2:
My memory from my HP-UX days says to use 'cpio', BUT...
I tried that last night and got spurious errors about 'Truncating inode
number'. That didn't give me a very comfortable feeling about my backup.
QUESTION: Should I 'init 1' to force single-user mode? This would
minimize open files during the backup.
Option 3:
I could use 'tar', but that is not what I would consider a "perfect" backup.
Option 4:
I have another identical disk to my two RAID enabled disks. I could
pull one disk out of the array, swap in the empty one and force a RAID
rebuild. In essence, giving me a truly perfect backup.
BTW, you may be wondering why I'm so worried about backups... I am
about to upgrade to RedHat 7.2 and want a fallback position in case
things go horribly wrong.
Thanks,
Ted
