NetBackup is indeed a great package, and after a series of evaluations of multiple products, we selected it as our global standard at Swiss Bank. It is also fully supported under NT. Important to not that it does not use a modified version of GNU tar. It can create a tar compatible tape, but to do that you loose the ability to stream multiple clients together. As we are using DLT7000 drives and getting a good 4+ MB/s from each drive, the ability to multiplex 4 or more clients together to keep up with the drives ability is important. Have not tested the Oracle modules, but the Sybase modules work very well. Its concept of distributed servers, having one Master that manages all of the tables, databases, devices, etc, and several Slave servers that actually backup the data works well in most environments as well. Example is here we feed all of the backup logs, indexes, etc to a large unix based Master server and then split the backup duties (data to tape) amoung several Slave servers, including a NT slave for NT hosts to talk to.
