At least one recent tape must be off-site, etc. Not only for when the building burns down, but also because someone might break in and steal equipment. > However, you're right that disk has many advantages.

Our AIT2 drive automatically checks if everything is written reliably, and if not, it automatically rewrites the data. Makes me sleep better :) Sander.
