We're struggling with a good mechanism of backing up very large file
systems on Windows 2003 clusters.  A typical file system will be about
500GB with 10 million files.  NetBackup 4.5 gets absolutely horrible
performance compared to a similarly-sized file system with <1M files.

These systems are connected via GigE to a Solaris system with a SAN
connection to our L700 library containing SDLT drives.  A single backup can
take on the order of 4 days.

What optimization can I do?  FlashBackup might be an option, but it's
not available for Windows until 5.0 and we're not there yet.
