Support for NetBackup Auto Image Replication
You can use the NetBackup Auto Image Replication (AIR) feature to replicate from one media to another media with Veritas Data Deduplication storage: You have to create a trust relationship between two NetBackup primary/media servers to configure NetBackup AIR.
To set up trust between NetBackup primary servers
- Log on to the NetBackup primary server (NBU1) from the web UI.
- Navigate to Hosts > Host properties. Select the Edit primary server tab.
- Click on Servers > Trusted primary servers. Click Add. Provide the target NetBackup primary server (NBU2) FQDN. Click on the Validate Certificate Authority option.
- After verifying the CA fingerprint, click Next.
- Generate token on the target NetBackup primary server (NBU2) and use it for authentication. Or, you can specify the target NetBackup primary server (NBU2) credentials for authentication. Click on Create trust. The NetBackup primary server (NBU2) is listed in the Trusted primary servers tab.
- Repeat the same steps on the target NetBackup primary server (NBU2) to set up trust with the NetBackup primary server (NBU1).
To configure storage servers for NetBackup Auto Image replication (AIR)
- Configure the deduplication servers on the Access Appliances (both source and target) for AIR configuration.
- In case of AIR with KMS Encryption support, See Setting up Auto Image Replication (AIR) between two Access Appliances which have secure communication enabled.
- Add storage servers on the target NetBackup primary server ( NBU2) with the target Access Appliance MSDP server's FQDN and credentials.
- Log on to the target NetBackup primary server (NBU2) with the web UI. Navigate to Storage > Storage configuration > Add Storage server. Configure the storage server, disk pool and STU to complete the storage server configuration on the target.
- Log on to the source NetBackup primary server (NBU1) with the web UI. Navigate to Storage > Storage configuration > Add Storage server. Add the storage server.
- While adding the MSDP disk pool, add the replication target. Select the trusted primary server (NBU2) and the target storage server.
Scroll down and provide login credentials for the replication target storage servers. Click Add.
- Review the MSDP pool configuration and click Finish.
- Create an STU to complete the storage server configuration for the source.
- Relogin to the target NetBackup primary (NBU2 and navigate to the earlier configured disk pool. Click on the disk pool name and navigate to replication target option. Click Add.
- Select a trusted primary server (NBU1) and storage server. Enter the password for the deduplication service on the storage server.
- Verify that the replication target is added.
NetBackup AIR process:
Backup - This is performed on the originating primary server (source domain, NBU1). Clients are backed up according to a backup policy that is indicated by the SLP specified in the Policy storage selection. The SLP must include at least one replication operation to a similar storage in the target domain.
Duplication - Images are duplicated to the source domain secondary storage server.
Replication - Images are replicated from the source domain to the target domain.
Device notifies NetBackup - The storage server in the target domain recognizes that a replication event has occurred. It notifies the NetBackup primary server in the target domain.
Import - NetBackup imports the image immediately, based on an SLP that contains an import operation. NetBackup can import the image quickly because the metadata is replicated as part of the image.
To create Storage LifeCycle Policy (SLP) for AIR
- Create SLP Policy (import) on the target: cluster.
On the target NetBackup primary (NBU2), navigate to Storage > Storage lifecycle policies. Click Add.
Provide the SLP name. Click Add to add the import operation. Select Import from the drop-down. Select the destination storage STU. Click Create.
Verify the import operation, storage and SLP name. Click Create.
Verify that the Import SLP has been added.
- Create SLP Policy (backup, duplication and replication) on the source NetBackup primary (NBU1):
Log on to the source NetBackup primary (NBU1). Navigate to Storage > Storage lifecycle policies. Click Add.
Provide the SLP name. Click Add.
Select Backup from the drop-down. Select the destination storage pool as the local MSDP pool which stores the primary data backup. Provide retention type and retention period. Click Create.
Select the created backup operation on the SLP window, click on Add child to add the duplication operation as a child for backup operation.
Set the destination storage attributes.
Select the created duplication operation on the SLP window. Click Add child to add the replication operation as a child for duplication operation.
Set the destination storage attributes. Choose the target primary server and target import SLP policy.
Verify that the backup, duplication and replication operations are added correctly. Click Create.
- On the source NetBackup primary server (NBU1), create a policy and select the policy storage as the SLP you created. Configure the policy Attributes, Schedules, Clients and Backup selections.
- Run the policy manually. The backup job is responsible for the data backup. The duplication job is responsible for duplicating backed up data on source storage server. The replication job is responsible for the replication of data to the target NetBackup primary server.
- On the target NetBackup primary server (NBU2), verify that the Activity monitor lists the import job.
