I suspect you have these two backwards.

This is fine.

No, a single job backs up a single client. But, particularly when
backing up to disk, you can run multiple jobs concurrently.

Well, yes, sort of ... the Pool doesn't contain the raw disks, normally,
but rather file Volumes created on them. BUT .... given your scenario,
what I'd probably do is use metadevices to span or stripe those disks
into a single volume. And frankly, if one fails, used-but-working (or
even factory reconditioned) 18GB SCA disks are pretty cheap on eBay.
FCAL slightly less so, but I don't remember off the top of my head
whether the D1000 is an SCA chassis or an FCAL chassis. (I'm making do
with a pair of 711s, myself, in which I'm about to replace all the 9GB
disks with 36GB disks.)
