Slow restores on Windows Netbackup client
Ensure Full duplex with max speed set on all point's of transfer, NIC's and switch ports Eliminating CRC. Are the ports on the switches set to gig Full duplex and Nic's the same? Disable Virus scanners or verify they are not scanning incoming / outgoing files. Ensure files are not being restored to compressed drives and or directories.

Is it possible to fine the Netbackup Client for Windows (5.1 MP4) to get
performance during restores? It is taking 3 times longer to restore
large file servers during our DR tests than it takes to back them up. We
have done all the tuning we can do on the master server (running Solaris
9, NB Enterprise Server 5.1 MP4). We have gigabit switches and cards,
and decent servers. Granted we are restoring 2 million plus files on
each Windows file server.
Two things you can do. First, turn off multi-plexing if it's enabled.
This will slow down backups but speed up restores. Pick your poison
Seconly, use the FlashBackup client - this will significantly speed up
backups as well as restores. Millions of files on a single file system
will suck, pretty much no matter what you do, and it's not just Windows
that has the issue here.
