Justin,
How about this.
I will setup a new master at SITE B and connect SITE B mediaserver to this new
master server.
Now if I get the restore request for an earlier date before the new master
server went live I would have to run this from old master server which will
contact this media server.
How does this sound as solution??? others also please give your valuable
insights

What NBU versions and OS are at sites A and B?

Hi,
I've never used a master server as a media server for another master server's
restores and to have it be its own master server as well, I'm not sure if/how
that would work - I'll let others on the list comment on that one.
Aside from changing things around a bit (possibly partitioning the Site B robot
if SL8500 or similar) and buying new hardware, I'm not sure I see a clean way
to separate the two. The two big problems here are the different tape mediums
between the two sites and lack of new hardware. If you have an SL8500 and you
partition it, you could present the robot + 1-2 drives to the Site-A master
server, leave the media server intact at Site B. Then, build out a new
environment (master/media servers) (for the other part of the SL8500
robot/tapes) at Site B.
I'd be really curious how others would approach this as well.. I've only done
this one with mixed mediums and I migrated the data or let it expire for the
non-LTO drives so I had a common medium, then it was easier to
migrate/move/have restores in different locations.

Justin,
Thank you for quick response.
I have separate libraries at each site. SITE B is T10000C tape type and SITE A
is LTO3/LTO4 tape type.
The only time I would need the older master server is when restore request
comes for an older date and image data is still in old master server.
Another reason I wanted to upgrade existing media server is
1. I do not want to buy new server
2. All the devices Tape libraries and VTLs are already zoned and configured.
The retention on tapes is 7 years which is a very long time, and its an implied
problem because we simply can not wait for 7 years for spliting I really want
to loose some burden from one master server and I do not find it logical to
have just one master server.
Please let me know your further thoughts.
Anurag

Hi Anurag Sharma,
There are probably quite a few ways to approach this problem.
I've done master+media+robot moves/migrations on a regular basis for quite some
time.
The first question you have to ask yourself is for the data in Site B-how long
until the data expires on the tapes in this robot or can you move It to site A
in the meantime? My recommendation would be as follows:
1. Move the tapes with data on them from SITE B to SITE A
2. Add FORCE_RESTORE_MEDIA_SERVER MEDIA_B MEDIA_A in bp.conf so it will
restore from the media server in Site A (assuming the tape medium is
compatible).
3. Rebuild/re-install NetBackup fresh as a new installation at Site B and
setup accordingly.
4. I would advise against intermingling two separate master server
environments.
Justin.

Experts,
This is the current setup
1 Master server at SITE A
2 Media servers out of which 1 at SITE A 1 at SITE B
I would like to separate SITE A and SITE B so that I do not have dependency on
only one Master server which is a single point of failure , so basically I am
looking at upgrading SITE B media server as Master server.
We have separate VTL and Tape Library at each site.
VTL Zoning and Tape Library Zoning already done on SITE B media server.
In my mind it is just upgrading the binaries re adding the devices and pointing
the clients to new master server for new backups and still doing restores from
the old master servers for older data. Is there anything I am missing.?
If anyone has done it please share.
Anurag
