Hello

We have a fabric connected library backing up Network Appliance filers
using NDMP.  We are getting goog backup speeds (up to 55Mb/sec) to the
NDMP configured LTO 2 drives.  But restores are extremely slow - at
approximately 30 minutes per gigabyte.  Has anyone seen this behaviour
before?  If so, please can you let me know?  The setup details as below:

NetWorker Server - Solaris 2.9
NetWorker 7.2.2
LTO 2 tape drives in a Quantum PX720 library
Brocade Silkworm 3850 FC switch
NetApp F825 running OnTap 6.5.1 R1P5

Thanks in advance.

Rgds, Ram.
