Tape is probably not for personal use, certainly not these monster tapes.

A tape holding 185TB is probably going to be writing that data pretty
damn fast.

I haven't intentionally used a tape in years, but you back up
transaction data and father/grandfather/son.

The 3 level backup scheme works.  I once saw the primary backup
fail and had to work with operations to go back a generation,
re-run the transactions, etc.  We'd never tested it before and
there were a lot of doomsayers, but it worked.  This wasn't tape
though it was those 8 inch diskettes in a magazine.
