Michael,

You can go directly to your tape drive but you must realize, your
backups/archives will backup (queue) if you don't have enough tape
drives.
While a disk backup pool can handle many backups at once, a direct
to tape backup must wait it's turn. One thing we did discover regarding
direct to tape backup, was a tremendous increase in data transfer rate.
Going to our disk pool we averaged 700kb/sec. But when we directed the
data to our tape pool, we got 3Mb/sec..(3590 tape drives)
