Greg,

If you want to use NetBackup with NDMP to back up the filer, you need to have at least one direct attached tape drive connected to the filer(not considering a three way NDMP backup using two filers with a tape device direct connected to the remote filer). You can dedicate one or more drives from an existing library controlled by NetBackup, or you can attach a new/different library to the filer(yes, the filer does support a locally attached library). Either the NetBackup host (NDMP client) or the filer can be direct connected to the robotic portion of the library(assuming the library has individual scsi ports for the connection). In the end, NetBackup ends up controlling the library either way. If the robot is direct connected to the NetBackup host via scsi, NetBackup controls it. If the robot is connected to the filer via scsi, the NetBackup host sends scsi cdb's via NDMP to the robot through the filer, thus the robot is still controller by NetBackup. What other information or assistance do you require?

Hi all,

I'm kind of new to the this filer business and I have a question about backing it up. We have an F720 on site that isn't doing much since we aren't backing it up. I need some options on how to do this. We currently back up our other systems vith Veritas Netbackup and a tape library. Now, my question(s) is if I want to use Veritas to back up the filer using NDMP, do I have to dedicate a drive on the remote tape library to the filer? Will the filer support a locally attached library, and if it does, does Veritas control the library or does the filer?

Thanks for your help

Greg
