Restore is disabled because backups are deleted during missing heartbeat processing

Details
Restore is disabled because backups are deleted in these three scenarios:
  • The WLMS plugin is disabled while the VMs continue to run.
  • The WLMS plugin is disabled and the VMs are then shut down.
  • Required policy permissions that allows DP to check plugin or VM status were removed.

In all these scenarios, after some time, the managed instances become invisible, the servers appear in an UNKNOWN state, and backups are deleted due to missing heartbeat processing. These errors are caused by missing plugin communication. After the plugin is restored, the managed instances and servers become active again upon scanning. However, the previously created backups are no longer visible, indicating they have been deleted. As a result, the restore operation is also disabled.

Workaround

No known workaround.
