Troubleshooting issues after DD change in protection policy

You might encounter specific issues after you change the DD in an SAP HANA protection policy.

After you change the DD in a protection policy:

  • The PowerProtect Data Manager UI does not display any of the log backups.
  • Scheduled incremental and differential backups are not started until the next scheduled or manual full backup is started.
  • Incremental and differential backups can be started manually from SAP HANA Studio or the command line.

  • The PowerProtect Data Manager UI displays the following status for the incremental and differential backups: 

    A copy this copy depends on was deleted.
  • Manual deletion of any of these backups does not produce the expected results.
  • Backups between the two storage units can be recovered without errors. Performing restore with dependency chaining or replication storage provides details.

As a workaround, perform a full backup to the new DD system. Subsequent backups are displayed correctly in the PowerProtect Data Manager UI, and you can properly delete the subsequent user-specified backup copies as expected.
