This is almost identical to my backup server except I have 3x2TB drives in a RAID-Z pool. I agree with all the author's "reasons this is awesome" except my #1 reason is data integrity.
ZFS with RAID-Z does block-level checksumming and automatic healing as you access your data. Combine that with a weekly scrub (touches every block so any silent bit flips are healed) and I can do away with my fears that my precious bits are rotting away.
- Gibheer 14y agoZFS uses block-level checksumming for every block. The auto healing can be used when there is a second copy or another way to rebuild that block, read Raid-Z. So you get the auto healing already when using mirror.
