Another coupld of questions :
1. Is it possible to make it disk stage to more than one tape drive in
parallel, i.e. multistream? It seems like one disk staging area will only
use one tape drive at a time, which is a shame.
2. Do multiple retentions get duplicated to the same tape? Seems to me that
now we have set some infinite-retention backup schedules, all of our tapes
are going to be infinite-retention.
Thanks, Phil

In theory, I agree...in practice, I haven't found it worked that well..
:o(
The reason I'm having issues is due to only having a 90 Gig DSSU. To
backup 5 machines, each with around 15-20 gigs of data......(total of
all 5 is about 80 gigs.)
However, we're using the DSSU (comprised of left over un allocated space
on a couple disks) to back these machines up over a 10M excrypted link,
which only passes about 300KB/s, and we can't afford to have these 5
machines consume a tape drive for 20+ hours for full backups.
We do have a Enterprise storage solution going online in Q3, so
hopefully I'll get a SAN attached Terabyte DSSU then!
;o)
