Different EVA, but the EVA I have a 4TB Disk presented to does
have other systems attached!
Problem I see with EVA is that its not really a "physical"
disk its backing up to! Its virtual.... a Volume made up of any disk. Its a
large LUN I guess
s.
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?

LTO4 drives/Tapes Disks are vdisks from eva6400 - 4TB Volume RAID5 setup.
HP EVA is an enterprise array Solution.
Many systems SAN attached fibre. S.

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?

Tape Libraries 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 ?

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. From:
