Configuring SQL Server backups when an availability group crosses NetBackup domains
When you have an availability group that crosses NetBackup domains, you can use Auto Image Replication (A.I.R.) to replicate backup images to another NetBackup domain.
The following storage must be configured in the NetBackup source and target domains:
For OpenStorage, a disk appliance of the same type in each domain. The disk appliance type must support NetBackup Auto Image Replication (A.I.R.).
For NetBackup deduplication, the storage that NetBackup can use for a Media Server Deduplication Pool in each domain.
Configure the domain where the backups occur as the source domain. Then configure the domain where you want to restore the backups as the target domain.
