Managing migrated backups to a Database Availability Group node

When you configure IBM Storage Protect Snapshot to back up databases in a DAG to a common DAG node, all DAG databases are backed up with the new DAG node name.

Before you begin
If you are migrating from an IBM Storage Protect Snapshot version that is earlier than V3.2, manage the backups from the previous versions by following these guidelines:
  • Do not mix backups that are created with previous versions of IBM Storage Protect Snapshot with new backups that are created by using the DAG node. To separate the backups, keep the previous backups under the previous Data Protection node name that is defined in the dsm.opt file in the C:\Program Files\Tivoli\tsm\TDPExchange directory, and use a new DAG node name to store the new backups.
  • To view or restore a backup that is stored under the previous node name, you must change the IBM Storage Protect Snapshot configuration.
  • You must manually delete backups over time if the old backups are no longer useful.
Procedure
  1. After you complete your migration, ensure that the first backup you do is a full backup.
  2. To view and restore backups that are stored under the previous Data Protection node name, complete these steps:
    1. Remove the DAG Node by using the General properties page, configuration wizard, or the set command on the command line.
    2. Restart or refresh Microsoft Management Console (MMC) or command-line interface.
    3. Click the Recover tab in MMC, or run a tdpexcc query tsm * command.
      Because the DAG Node parameter is not set, IBM Storage Protect Snapshot lists the backups that are stored under the IBM Storage Protect Snapshot node.
    4. Proceed to restore one or more of the listed backups.
  3. Delete the backups that are expired.
