Configuring the auto image replication
Auto Image Replication (AIR) enables automatic replication of backup images from a source NetBackup domain to a target NetBackup domain for disaster recovery. Auto Image Replication is configured using a Storage Lifecycle Policy (SLP) that includes backup and replication operations.
Before you create an SLP, ensure that:
Source and target SpanFS clusters are paired.
Storage domains and LSUs are created and paired between the clusters.
Both SpanFS clusters are added as storage servers in their respective NetBackup domains.
Disk pools and storage units are created on both the source and target NetBackup domains.
An import type storage lifecycle policy exists on the target NetBackup domain
Note:
AIR requires two NetBackup domains: a source domain and a target domain. Replicated images are cataloged and managed independently on the target domain.
To configure Auto Image Replication (AIR)
- In the NetBackup web UI, on the left, click Storage > Storage lifecycle policies.
- Click Add to create a new storage lifecycle policy.
- On the Storage lifecycle policy page, enter the storage lifecycle policy name.
(Optional) Configure Data classification and Priority for secondary operations.
- Click Add to add an operation.
- In the New operation window:
From the Operation list, select Backup.
Under Destination storage attributes, select the source storage unit backed by the source SpanFS cluster.
Configure the required Retention settings.
Click Create to add the backup operation.
- Select the Backup operation in the operations table, and then click Add child.
- In the New operation window:
From the Operation list, select Replication.
Under Destination storage attributes, select replication target storage servers (across different NetBackup domains) for the source storage server.
Under Target import SLP, select the import storage lifecycle policy created on the target domain.
Configure the required Retention settings.
- (Optional) Configure additional settings such as postponing replication until the source copy is about to expire.
- Click Create to add the replication operation.
- Review the storage lifecycle policy configuration, and then click Create.
