Hello all,
I currently have an issue where a media server (Windows, MSDP, 7.6.0.3) is running slow due to the link between the master and media servers.
What I would like to do is migrate all the backup data from this media to the master which is also another media server so that I can then rebuild the original media server as it's own netbackup domain master/medi server.
Is this possible and what would be the best way to go about this?
Thanks!
Chris

Hi Chris,
I think the 2nd last line there might be the issue. Is this diskpool setup to replicate to another using AIR?
Like i said I don't have anything to test with but maybe start looking there....

Chris,
Review the following TN: TECH150431
How to remove NetBackup Media Server Deduplication option (MSDP) configurations from a NetBackup environment.
http://www.symantec.com/docs/TECH150431
Please note: you will need to duplicate any images you intend to keep from your MSDP media server to your master.
If you have any additional questions, please let us know.

Hello,
What storage media does your Master/Media have? Tape, Adv Disk, or MSDP as well?
If its anything other than MSDP you're in for a looooong duplication exercise. If its MSDP, or if you can install one (given that your environment isn't too big as its not really recommended to run msdp on master), then you could
Hope that helps.

Tom / Riaan,
Thanks for your replies, both great responses to get me going.
Is it possible to do a manual image duplication between NB domains, so that once the media server has been decommissioned and rebuilt as a master/media I can then copy the images back?
Cheers,
Chris

Hi,
Yes you can do that. There was a post on the forum recently about replicating images with AIR retrospectively. SDO posted a bunch of good info.
##EDIT: Found it https://www-secure.symantec.com/connect/forums/can-we-retrospectively-replicate-backup-images-another-master

Riaan,
Thanks for that link, unfortunately I am getting the one scenario which didn't work ....
...fragments exist on media which does not support replication.
Is there any other way round this?
Thanks.
Chris.

That message relates to non msdp / ost images, which means they're on tape or advanced disk. In your scenario we should be working with MSDP images so that wont affect you.
Unless I'm missing something.

I'm only using MSDP and this is a response from the nbreplicate command for an image to the new master, which I had already successfully tranferred from the old media server to the current master using bpduplicate!?
This is the command used....
nbreplicate -backupid BACKUPID -cn 2 -rcn 1 -slp_name LD_MOVE -target_sts MASTER -target_user USERNAME -target_pwd PASSWORD
anything else I can check?

Can you show bpimagelist -l of the backup image

This bpimagelist shows copy number 1 but you used 2 in the nbreplicate?
09-17-2014 06:46 AM
Sorry, I had used copy number 1 in practice.
09-17-2014 08:49 AM
HAve you setup AIR to the new MSDP/Domain? Is that working?
09-18-2014 01:20 AM
I had only setup the destination import, but have now setup both ends and tested successfully. Running the command again still shows same error...
09-18-2014 02:23 AM
I can't test, don't have enough resources. Can you post all your outputs here. Maybe we find something.
09-18-2014 06:05 AM
Riaan, appreciate your help on this so far! Would you please explain what you mean by outputs?
09-18-2014 10:11 AM
What you're running from CLI, plus the error messages.
