You're probably running into disk IO
issues with all of the other data. Are you reading the data off the same
EVA array that you are writing it to?

It would depend a lot on what
your “disk”(s) and “tape”(s) are. We typically see much
faster backup to Data Domain than to Ultrium Tape.
Is your target “disk” part
of the server itself? Externally attached storage? SAN? NAS?
iSCSI? ATA drives? Fibre drives? SSD Drives?
Is it JBOD? RAID1? RAID5? RAID10? Are you doing
dedupe? If so is it at the server or at the target?

I ran a test backup to Disk and
found that the backup took over 7 hours. when running the same backup to
tape, it took 5 hours!
The files was a mixture of small
profile type files and folders.
So not too impressed with the
speed. Unless some tuning can be done ?

Watching this thread I have to
put in my 2 cents.
One of the key points is having
to have copies offsite.
So our search of de-dup has to
include replication to the dr site where we have a live master, and we
need to be able to mount that replicated copy on to that master to be able
to do restores.

This would be a very good time for you to investigate utilizing client
side de-dupe, Pure Disk, Media Server De-Dupe, one of the NBU appliances
(which have storage built in), or a Data Domain.

or a Quantum ;-)
