NBU7.6.4 Recovery Options

Hi,

We are moving to upgrading from netbackup 6.5 to 7.6.4.

As we have backups with 3 months retention period, i am thinking if we can still recover even after upgrading from 6.5 to 7.4.

Here are the facts:

1. New server with NBU master and media on 7.6.4 (different network backup LAN)

2. Clients with NBU client 6.5 will be uninstalled and installed with NBU 7.6.x. (is this recommended or can direct upgrade??)

3. Old NBU master and media will be retained until backups expires (3-6 months)

4. How can we do a restore from OLD NBU?

5. We are using RMAN backup with NBU, what is the recommended approach when we need to restore from old backup?

 

Thanks in advance.

  • thanks Riaan.

    The new backup system is on different backup vlan.

    Does it mean, when we do restoration, we need to reverse to old backup too?

     

  • You are creating a lot of headaches for yourself by not upgrading and recovering catalogs on the new server.

    Easiest with your approach will be to use old master to merely list backup images and tapes that are needed, then import the tapes in the new environment and restore there.

    Important to keep tapes from old server separate to prevent accidental overwrite in new environment.  

  • Hi Marianne,

    Thanks for your reply.

    "Easiest with your approach will be to use old master to merely list backup images and tapes that are needed, then import the tapes in the new environment and restore there."

    Is my understanding correct??

    1. keep old master server up for the purpose of listing backup images and tapes that will be needed for future restore request

    2. import the tapes in the new environment - restore request
