Archiving Photos

[alexglee]

Hello all. I am looking for the most effective (cost/time/etc) way to archive and keep photos backed up. Some background: I've lost photos before due to my own stupidity of formatting the wrong drive. After data recovery, the photos are all scrambled, so I want to make sure that after I sort them out this time, I won't mess it up again.

I devised a strategy after doing some searching and talking to people. In the interest of keeping the first back up and incremental backups quick, I have employed Seagate's Thunderbolt SATA adapter.

I would like to:
- Time machine my computer via a Thunderbolt HD (daily stuff, including a copy of the photos).
- ONSITE backup USB HD
- OFFSITE backup #1 (stored in bank vault) Thunderbolt HD
- OFFSITE backup #2 (stored in another off site location) Thunderbolt HD


I was doing some research and found that companies are employing RAID6. I was thinking about splitting each drive in to 3 partitions and doing the same.

Thoughts on this strategy? Do you have a better one?
