Yes, they will compete. taper writes whenever it has complete images to
write -- parallelism is one of the benefits of the holding disk. That's
why, with faster tape drives, a holding RAID becomes necessary.
Would software RAID be sufficient ? I need stripping I presume ? Al I
have is a standard PC as a server. I don't want to end up with an
expensive tape server, we switched to amanda basically to REDUCE
costs...
Sure, a software RAID0 would do, given sufficient disks (which for LTO2,
could well be just 2). Heck, 1 disk *may* be sufficient for LTO2 --
testing will let you know. Stepping up to LTO3, though, definitely
requires actually putting thought/$$ into the backup server.
I'd like to point out, though, that that cost really has nothing to do
with amanda itself. It's just that these tape drives are *fast*, so
feeding 'em ain't as easy as feeding tape drives used to be.
