Misha,
Try 256 kB
if you search on "LTO-3 SIZE_DATA_BUFFERS" and "netbackup tuning
guide" you will find a number of very useful documents. As a starter,
have a look at -
h71028.www7. hp .com/ERC/downloads/5982-9971EN.pdf
http://seer.entsupport.symantec.com/docs/244652.htm
You should be aware that Windows server 200 SP1 limits the
SIZE_DATA__BUFFERS to 64kB, see
http://support.microsoft.com/kb/907418/
this seems to be fixed in SP2 (thanks to Ric Davis for that info)

REMEMBER- There is only one certainty about storage systems - they
*will* fail !
This includes backup and archiving systems.
If you want to be paranoid, make your own backups as well.
