MSDP Data migration

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

1. Generate a list of all images on the old MSDP with bpimmedia and keep it somewhere
2. Target the new (or existing) master server MSDP in your policies
3. 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.
4. 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.
5. Once you're sure you've got all of it duplicated you can expire the OLD one
6. Then you can remove the SLPs (if you had any).
7. 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.

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?
