Ask Slashdot: What's The Best Way To Backup Large Amounts Of Personal Data? (foxdeploy.com)
An anonymous Slashdot reader has "approximately two terabytes of photos, currently sitting on two 4-terabyte 'Intel Rapid Storage' RAID 1 disks." But now they're considering three alternatives after moving to a new PC:
a) Keep these exactly as they are... The current configuration is OK, but it's a pain if a RAID re-sync is needed as it takes a long time to check four terabytes.
b) Move to "Storage Spaces". I've not used Storage Spaces before, but reports seem to show it's good... It's a Good Thing that the disks are 100% identical and removable and readable separately. Downside? Unknown territory.
c) Break the RAID, and set up the second disk as a file-copied backup... [This] would lose a (small) amount of resilience, but wouldn't suffer from the RAID-sync issues, ideally a Mac-like "TimeMachine" backup would handle file histories.
Any recommendations?
This is also a good time to share your experiences with Storage Spaces, so leave your answers in the comments. What's the best way to backup large amounts of personal data?

You forgot checksumming and verification after transfer.....You have something on the other drive after the transfer, you wont know what until you verify it.
By the tits of Baal, rsync or xcopy /v or robocopy in combination with fciv.
