Whoa, not sure what you mean Mark.
!) Did you install NBU MP3? This had fixes specific to remote-NDMP. It
increases the memory buffer size and usage on the media server and
increases
performance a lot.
>>>> I had MP 3 installed, but now that you mention it, I may not
have had the NDMP patch on that media server since it was not originally tasked
to be a remote NDMP server.
2) Backing up a NAS box by following the NFS mount will not preserve the
ACLs.
>>>>>>True. Our primary concern was getting the data off, even if the
ACLS went away.
Why dedicate a tape drive to a single NAS box when it can be used for
many?
>>>>>> 2 reasons. Given that the filers are configured with about 4 TB
of data each, the minimum number of tape drives estimated to be needed to meet
the backup windows was 2. So I need 2 drives to get the throughput I need to
back the data up in the window I have.
The other reason is resiliency. If I have all my filers backing up
through one system, and I lose a drive or something, I lose the ability to
backup all my filers.

Karun
Run, don't walk, away from remote NDMP. At least in it's current
Configuration, you would probably be better off backing up via NFS
mount.
I tried this with disastrous results in a SAN environment.
NDMP direct (sic: there might be a fiber switch in the middle in a
SAN, etc.) works great.

Hi Guys !
For configuring NAS on Netbackup, which of the following is the best
setup.
1. Attach the Tape drives directly to the NAS through SCSI
2. Attach the Tape drives to the Netbackup Media Server and back data up
through Giga bit ethernet from NAS to the Media server.(Remote NDMP)
I would like to know how you guys have setup NAS in your environment.
Any
tips would be helpful as I am supposed to set up this in couple of
weeks.
Thanks,
- Karun
