Using concurrent backups and spooling is a _big_ win when running
incrementals as otherwise these will always cause shoeshining if pointed
directly at the tape drive.
Once you're using spooling, you can run multiple simultaneous backups
and shorten up the backup window even further.
My spool disk area is about 300gb with a max chunk size of 100Gb
(recently converted to SSD for extra speed). A lot of the machine full
backups end up in one piece on the tape as a result. (Data backups are
for 1Tb partitions and always end up in several chunks)
