a huge one terrabyte database or several databases adding up to
one terrabyte. With today's (2005) technology, it takes around
20 hours to back it up to tape. To speed it up, one would have
to configure more tape drives. Multiple backup devices e.g. \\.\TAPE0,
\\.\TAPE1, \\.\TAPE2, \\.\TAPE3 and \\.\TAPE4, work in parallel
thus reducing backup time to 4 hours in this example.
