47 MB/sec for a windows SAN media server with SCSI attached library with
LTO2 drives.
The rest ran at around 12-15 MB/sec on a 1GB network. Servers were IBM
435s and SUN
V40zs. BTW the SUNs made the IBMs look like 286s.

Re: [Veritas-bu] Backup speeds Windows servers
I'm curious to hear what kind of speeds (mbs/sec) others are getting
backing up windows servers.
Running Netbackup Enterprise 5.1 mp6 under Solaris10 on master/media
servers.
a. Using brocade 2g ports 48000 director.
b. IBM Ultrium LTO Gen2 drives
c. Sun branded Qlogic 2gb cards. single port feeding each
tape drive.
d. The storage on the windows servers is FC attached
Hitachi Tagmastore 9990. (Very fast drive configuration.)
e. Servers are HP G5's also 64 bit. Some are 32 bit. Seems
32 bit servers are actually faster.
note: Some of my other backups such as Solaris, Linix and Netware
can get as much as 20 mb/sec with this configuration.
So why are the windows servers so slow? Any one have some kind of
idea what may be a cause? Or it is what it is! Windows!
