If for some reason your system isn't able to supply data to the tape drive at fast enough rate, the drive keeps stopping-repositioning-writing-stopping again, which then takes extra time and causes extra wear to the drive and the tape. Also, if you need to manually change tapes during the backup, the data can be spooled nonstop, resulting in more consistent set of files (no time gap due to waiting for the tape change, that could take for hours sometimes)
On the negative side of spooling, you'll need a disk volume big enough where to spool, and a slightly more complicated configuration. -- TiN ------------------------------------------------------------------------- Take Surveys.
