Our new master server is Solaris, not Windows, but we did recently add a
largish Windows file server client.  It's currently dumping about 7TB
to LTO4 in around 24 hours.  In this case the bottleneck is the client's
Gigabit Ethernet, which runs at a steady 80-90MB/sec the whole time.

No NTFS compression on the Windows client, no FlashBackup, no multiplexing,
and buffer settings are:
        SIZE_DATA_BUFFERS     262144
        NUMBER_DATA_BUFFERS   32

The client is Win2k8R2 server, storage is Dell MD1200, 11x 2TB nearline
SAS drives configured as a RAID-6 array.

Regards,

Marion
