Configure Auto Image Replication (A.I.R.) and duplication
The backups that are generated in one NetBackup domain can be replicated to storage in one or more target NetBackup domains. This process is referred to as Auto Image Replication (A.I.R.).
NetBackup Kubernetes supports Auto Image Replication from a Media Server Deduplication Pool (MSDP) in one NetBackup domain to a Media Server Deduplication Pool (MSDP) in another domain. NetBackup uses storage lifecycle policies (SLP) in the source domain and the target domain to manage A.I.R. operations.
The Auto Image Replication (A.I.R.) supports all schedule types which includes Differential Incremental, Cumulative Incremental, and Automatic schedules.
For more information about configuring Auto Image Replication, refer to the About NetBackup replication chapter in the NetBackup Administrator's Guide, Volume I.
Note:
A Kubernetes A.I.R. configuration requires NetBackup primary and media servers of version 10.0.1 or later.
To configure Auto Image Replication (A.I.R.) and duplication for Kubernetes backups
- Configure an Auto Image Replication between two NetBackup primary servers.
Establish the trust relationship between two primary servers for interdomain operations.
Log on to the source primary server, on the left, click Hosts > Host properties to build a connection between a source and target primary server.
Select a source primary server. If necessary, and click Connect. Then click Edit primary server.
Click Servers. On the Trusted primary servers tab, click Add to add a source server.
Click Validate Certificate Authority, then click Next to proceed with the certificate authority validation.
To create a trusted primary server, select from the following options:
Select Specify authentication token of the trusted primary server to add an existing token or create a new token for the source primary server.
Select Specify credentials of the trusted primary server to add user credentials for the source primary server.
Click Create trust.
The database for the host properties is updated successfully.
Click Save.
- Configure a Media Server Deduplication Pool (MSDP) storage in the source primary server and add a replication target in MSDP disk pool.
On the left, click Storage > Disk storage.
Add an MSDP storage and disk pool.
Click the Disk pools tab and click Add.
Select a trusted primary server and a target storage server.
Add user credentials for the replication target server in the Username and Password fields.
Click Add.
- Create SLP with Import operation in the target primary server.
On the left, click Storage > Storage lifecycle policies. Then click Add.
In the Storage lifecyle policy name field, enter the policy name and then, click Add.
From the Operation list, select Import.
In the Destination storage list select an MSDP storage unit.
Click Create.
- Create Kubernetes protection plan with the Create backup from snapshot option to enable the replicate copy option.
On the left, click Protection > Protection plans. On the Schedules tab, click Add schedule.
- In the Snapshot and backup copy optionssection, select Create backup from snapshot option to enable the replicate and duplicate copy options.
- Select Create a replica copy (Auto Image Replication) of the backup from snapshot option, and set a time duration to retain the replica copy.
Note:
Auto Image Replication can only be created on the trusted NetBackup primary servers.
- Select Create a duplicate copy of the backup from snapshot option and set a time duration to retain the duplicate copy.
- Click Add.
- Continue creating the schedule in the Start window tab, as described in theManaging protection plans section of the NetBackup Web UI Administrator's Guide.
- Click Next.
- On the Storage options tab, select the storage units to backup from snapshot, replicate, or duplicate copy.
Note:
For Backup from snapshot and duplication, you can add simple storage units. But for replication, you must add a trusted storage unit with an import storage lifecycle policies (SLPs).
- To the right of the selected backup options, click Edit to modify selected the storage units for backup.
For the replica copy option, select the primary server for replication copy. Then click Next.
Select an import storage lifecycle policy that is defined in the trusted server and then click Use selected replication target.
- Continue with the steps in the wizard.
