How to configure NetBackup Auto Image Replication (AIR)?

By | February 2, 2015

In the previous post I showed NetBackup Auto Image Replication architecture overview. In this post I will describe how to configure it with using MSDP (or OST compatbile Storage Server).

NetBackup provides the ability to establish a trust relationship between replication domains. A trust relationship is optional. The following points describe how a trust relationship affects Auto Image Replication (AIR):

  • Trust relationship - You can select a subset of your trusted domains as a target for replication. NetBackup then replicates to the specified domains only rather than to all configured replication targets.
  • No trust relationship - NetBackup replicates to all defined target storage servers. You cannot select a specific host or hosts as a target.

To show how to configure AIR I will use:

  • two NetBackup Master/Media Servers: kyoto.nihonno.domein and beppi.nihonno.domein
  • backups done via kyoto.nihonno.domein and replicated via AIR to the beppi.nihonno.domein
  • set up trust relationship between kyoto.nihonno.domein and beppi.nihonno.domein

 

To configure NetBackup Auto Image Replication (AIR) please follow the steps:

  1. Configure Media Server Deduplication Pool (MSDP) or OpenStorage (OST) compatible Storage Servers in the both NetBackup domains.
  2. Create a trust relationship between NetBackup Master/Media Servers - kyoto.nihonno.domein and beppi.nihonno.domein. To set up the trust please double click on the Master Server (kyoto or beppgi) and select Servers then click the Trusted Master Servers tab. Click Add. Provide the remote master server name and credentials. Click OK.How to configure NetBackup Auto Image Replication (AIR)
  3. The trust should be created.How to configure NetBackup Auto Image Replication (AIR) 2
  4. Automatically the trust has been created also in the second Master Server (beppi).How to configure NetBackup Auto Image Replication (AIR) 3
  5. On the second Master/Media Server, in the NetBackup Administration Console, expand Media and Device Management > Credentials > Storage Servers (1). Select the MSDP storage server and on the Edit menu, select Change (2). In the Change Storage Server dialog box, select the Replication tab (3). On the Replication tab, click Add (4).  Select a trusted master server if you want to replicate backup images to a subset of available targets. Enter the Password for the deduplication service on the target storage server (5).How to configure NetBackup Auto Image Replication (AIR) 4
  6. The target Storage Server kyoto.nihonno.domein has been added. Click OK to close the window.How to configure NetBackup Auto Image Replication (AIR) 5

  9. Create a SLP policy -  in the NetBackup Administration Console, select NetBackup Management > Storage > Storage Lifecycle Policies. Right click and click New > Storage Lifecycle Policy. Type name of policy (1). Then click Add (2) and select Source storage operation as Import (3). Optional:  configure Retention type.How to configure NetBackup Auto Image Replication (AIR) 8

  11. On the second Master Server, create a SLP policy and and Add Source Storage Operations as Backup.How to configure NetBackup Auto Image Replication (AIR) 11
  12. Click Add to configure the replication from the first Master/Media Server to the second Master/Media Server.How to configure NetBackup Auto Image Replication (AIR) 12
  13. Select Source storage operations as Replication (1) and specify the Target master server as the second Master Server and import SLP from the second Master Server (2).How to configure NetBackup Auto Image Replication (AIR) 13
  14. Confirm that you have a Backup and Replication operations as shown on the below figure. Click OK to save SLP.How to configure NetBackup Auto Image Replication (AIR) 14
  15. In the first Master Server, please create a policy and select policy storage as SLP you created. In my case the SLP name is Backup_Test. Configure policy attributed and also Schedules, Clients and Backup Selections.How to configure NetBackup Auto Image Replication (AIR) 15
  16. Run manually the policy. You should see two jobs: the first one responsible for a data backup. The second for a replication of data to the second Master/Media Server.How to configure NetBackup Auto Image Replication (AIR) 17
  17. On the second Master Server Activity Monitor, you should see an import job.How to configure NetBackup Auto Image Replication (AIR) 16
  18. On the second Master Server, if you search images in the NetBackup Catalog, you should see backups from the first Master/Media Server.How to configure NetBackup Auto Image Replication (AIR) 20

Note: I have described a situation when images are replicated from the first NetBackup Domain to the Second NetBackup Domain. NetBackup Auto Image Replication supports cross-domain replication so also you can configure a replication from the Second NetBackup Domain to the First NestBackup Domain. Repeat steps 9-15 with exchanging First Master Server with Second Master Server accordingly.  In my case, I have used Master and Media role on the same machine so please notice that the replication is done between Media Servers (=Storage Servers).

    Very helpful instructions!! Quick Question:

    From the instructions below, you reference an MSDP storage server, should we have a "replication" tab on our Storage Servers if they are Data Domain based Open Storage Storage Servers?

    Our OST environment is up/running, we are at 7.6.03 .. our plugins are at 2.6.3,, and the DD is an 860.

    5.On the second Master/Media Server, in the NetBackup Administration Console, expand Media and Device Management > Credentials > Storage Servers (1). Select the MSDP storage server and on the Edit menu, select Change (2). In the Change Storage Server dialog box, select the Replication tab (3). On the Replication tab, click Add (4). Select a trusted master server if you want to replicate backup images to a subset of available targets. Enter the Password for the deduplication service on the target storage server

      Thank you for your post.

      Nope, you do not configure "replication tab" on Storage Servers in NBU GUI. You have to "pair" Data Domain Systems (using DD command cli or GUI) and pairing must be done prior to configuring NetBackup disk pools or NetBackup Storage Units.

      I will write a post with steps how to configure DD and NBU with AIR, but still in the queue... no time 🙁

        Hi Mariusz,

        Did you got chance to create the doc for DD and NBU with AIR.

          Hi Nitesh,

          Unfortunately I haven't. However, it will be the next post regarding NetBackup. Please stay tuned. Thx.

    Hello,

    The post was very helpful.
    Can AIR be done from tape to tape? Or is disk required?

    Thanks -Ana

      Hi,

      AIR works only between supported MSDP/OST storage but later you can duplicate to tape via SLP.

    Hi Mariusz,

    Thanks for the wonderful doc. keep doing the excellent work.

    I want to understand you created import on first master and backup and replication on second master.
    What did it mean?Can you please make me understand?
