Summary

Adding or deleting a volume on a DPX open storage server can cause a backup to fail if the Advanced Protection Manager service is not restarted. When adding a volume, the new volume is not monitored for drive space availability and backups to it fail. Deleted volumes appear as available and backups to it fail as well. To resolve this issue, restart the Advanced Protection Manager" Windows service."

 

 

Symptoms

 

 

A backup to a recently added volume on the DPX open storage server fails with the error:
