A single hard drive is not a good idea. Even two hard drives are
somewhat risky. I generally feel comfortable when I have three hard
drive copies with one off-site or two RAID-5 copies with one off-site.
If you're in the Windows environment, a great program for managing
the redundant copies is Vice Versa Pro from www.tgrmn.com and I
strongly urge you NOT to propagate deletes. Delete files that are no
longer needed manually from each copy.
I also MUCH prefer network attached storage to locally attached
storage (USB/Firewire). My workflow is to ingest to a local drive and
then at the end of each session run a VVPro script to push the new
files out to the two RAID-5 NAS boxes (one off-site). That script
also calls the Windows SHUTDOWN command, so the audio workstation
shuts off after the file transfer is complete.
Here are more details:
