I would like a confirmation:
I'm using amanda to backup only local (SCSI) hard drives (about 1TB).
In such a configuration are there any benefits from using a holding disk?
I hope the answer is as easy as the question but :-/
parallelism of multiple DLE's dumping at same time.
more consistant feeding of tape drive from a "single" disk file
rather than at dump program rate.
All of those benefits assume the I/O subsystem can handle the demands
being placed on it. A 6-disk RAID5 is going to be *very* hard pressed to
handle 2 read and 1 write thread all on the same volume simultaneously.
