Client Parallelism?  Is there an option I don't see it in the client record.
Device parallelism is 4 per drive. (this was the default)
Server parallelism is 24 (I changed it by guessing 6 drives at 4 makes 24)

Thanks, Rob.

Betreff: [Networker] Large Volumes & Speed..


I have some really large volumes that I need backed up on a regular basis,
there are 6 volumes around 600Gb each.  I added them to my normal cycle but
when it hits a full volumes it takes days to backup.  I currently run a
Windows 2000 server with two Dell PV-136T (Dell branded Adic Scalar 100)
with 3 SDLT320 drives per box.  It seems Legato only writes to one tape at
a time per volume, is this by design?  It has six drives available to use,
but only seems to write different clients to the six drives in
parrallel.  Any suggestions on speeding up large volume backups?  I run
Gigabit copper to my backup server, I feel the bottleneck is with Legato
and possibly the SDLT drive write speed may be a factor.  Any thoughts will
be appriciated.

-Rob.
