- Never
- All the time

A 750 GB drive goes for about $120, and for backup, an external backup
drive of the same size for about $160. That's all you need. RAID is a
waste of money for most music libraries.
For a library that's so large you can't afford to back it up to a
second set of hard drives (more likely a video library or a truly huge
music collection) then RAID 5, or better yet, RAID 6 makes sense.
I disagree. The OP complained about the hassle of restoring things from
backup. That's exactly what RAID saves you. Don't use hardware RAID
because the controller may fail and you may not be able to get it
repaired or get a similar replacement a few years from now. Use the
standard Linux kernel RAID (md) instead.
I recently had a hard disk failure in my colo machine which cost me a
lot of time.
My current setup is:
Home: Linux server with 3 1TB drives in RAID 5 configuration that store
music/photos/video/mythtv & personal files
Colo: 1TB drive that receives daily snapshots (rsnapshots) of
music/photos/personal videos & personal files (30 day retention)
I chose the snapshot/colo option because I know I'm not disciplined
enough for manual backups.
RAID is *not* a substitute for backups but it may save you a lot of
downtime and work.

Peter
