Fair enough points @tack and @Dewdman42 and @whiskers
But just to review the bidding, the RAID I'm using is mirroring my backup, not my original files, so the RAID is to protect against drive failure. The "originals" are on the DAW and the PC slave computers and, although they're on an automatic backup schedule, it's once a week, hopefully long enough to discover malware etc.*
Then I take the mirrors periodically and swap them out, putting the fresh ones in the bank. So I guess I have:
1. The original files
2. The backup of those files on an HDD
3. A copy of that backup on another HDD, mirrored; and
4. A copy at the bank.
The copy at the bank is of course out of date, but still a lot better than what would be left after a fire.
I had all my computers sitting by the front door for a week recently, watching ash fall around the house, so it's not a wholly theoretical risk. For me -- suddenly -- nothing happened. Some people were a lot less lucky.
*I actually have daily backups too onto a hard drive of Digital Performer (DAW) files and my Pro Tools recordings. That's the extra-extra backup in case I delete something.
That sounds much more thorough, I'd be comfortable with that. I was just pointing out a general pet peeve of mine, not digging on your solution Just dont forget to verify your backups occasionally and you're good!
