Greg,

The comments in my earlier email with regards to VERITAS NetBackup, NDMP and filers remains correct. Technote 3066 (#4 below) works as long as the NDMP compliant third party backup software supports it. VERITAS NetBackup does not currently (to the best of my knowledge) support performing an NDMP backup from a filer with data going to the Solaris or NT backup server with locally attached tape devices. Call me on 408-822-3308 if there are any questions, or you want to discuss this further.

A recent Network Appliance press release details plans to address the idle tape drive issue. It is well understood that direct attached, dedicated tape devices sit idle most of the time. The release can be found at:

I'm interested in the proposed NDMP backup testing with a dedicated GB ethernet network. What are the configuration details, when is testing scheduled to start?

Thanks, Bill Roth

I understand that you can do NDMP dump across the network to a media server... it is even mentioned in technote 3066, section 4.3 (# 4 below):

---- The NDMP protocol specification allows the following backup configurations: 1. Local backup from a filer to a SCSI-attached tape device 2. Three-way backup from a filer via the network to another filer with a local tape device 3. Backup from a UNIX or Windows NT server via the network to a NetApp filer with a local tape device 4. Backup from a NetApp filer via the network to a UNIX or Windows NT backup server with a local tape device ----

We currently backup filers via dedicated directly attached tape drives (using Veritas NetBackup)... but, this is a costly solution because the tape drives are idle probably 75% of the time. We will be testing NDMP across a dedicated GB ethernet network in the near future. Even if we see some decrease in backup throughput, it will good if we can get those 20 dedicated DLT7000 tape drives in S'Tek 9710's doing more work for us...

Is anyone already using a private network and NDMP to backup a filer?

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
