Re: HD Backup Workflow

I have started using bare SATA drives for footage and media backup. There are many external boxes (eSATA is fastest) that will let you plug in a bare drive. I happen to use a swappable internal SATA mount that lets you slide in a bare drive, no rails or extra hardware needed.
Critical work gets backed up twice; I label my drives in A/B sets.
As Bob said, RAID 1 won't do the same-- a catastrophic failure will take out both drives. If you have irreplaceable work, I'd suggest a third and forth drive stored off-site. A good branded 500 MB drive is about $50 these days. You can even get nice plastic cases to hold bare drives on the shelf.
