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. --Tom

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 Generate a list of all images on the old MSDP with bpimmedia and keep it somewhere Target the new (or existing) master server MSDP in your policies Ensure that all SLPs (if you're using them) that refer to the old MSDP finish their images so you can then remove them later. Start duplicating from OLD to NEW MSDP (if you had run step 2 then the new MSDP would have been seeded so duplications of the backup images from the OLD one should run fairly quick). I would suggest a script that use the list generated in step 1. Build in some logic to check images are now located in both locations. Once you're sure you've got all of it duplicated you can expire the OLD one Then you can remove the SLPs (if you had any). Then decommission the media server. 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.

HAve you setup AIR to the new MSDP/Domain? Is that working?

I had only setup the destination import, but have now setup both ends and tested successfully. Running the command again still shows same error...

I can't test, don't have enough resources. Can you post all your outputs here. Maybe we find something.
