I'm a member of a production company and we're preparing for our first feature film. We've been discussing methods of data storage to keep all of our original content safe (for as long as possible). While we understand data is never 100% safe, we'd like to find the safest solution for us.

We've considered:

• 16TB NAS for on-site storage

• 4-5 2TB hard drives (cheap, but not redundant), copy original footage to drives then seal in static free bag

• Burn data to Blu-Ray disks (time consuming and expensive: 200 disks == $5000)

• Tape drive(s)?

I know the least about tape drives, except the fact that they're more reliable than disks. Any experience/knowledge with this amount of data is hugely appreciated.
