It might work for you, which is fine; however, there is a world of
difference between RAID and backups.
I agree but he may be talking about using raid 1 (mirroring) to swap out
a spare disc which is what I do. However unless you do this daily (which
I wouldn't advise even if scsi), you still need to backup any changes
since the last disc swap out. For this I use a combination of rsync to
another system and tar up my complete home directory daily.
When I plan an upgrade, I always swap out the mirror disc and ensure the
new disc has updated before starting. This has worked well when the
upgrade went t*ts up, ensuring a rapid recovery.
