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!
