You will receive an alert when a certain percentage of free space is left on a disk
Depending upon how you set up your storage options, you will receive an alert when a certain percentage of free space is left on a disk. Below is an example of a BDS Low Space Alert received once the threshold is reached.
Figure - BDS Low Space Alert
To resolve this:
If you need additional space even after the purging of data consider add additional storage to the Unitrends appliance, but do not exceed the recommended 10TB of storage for VMware/Hyper-v or 5TB of storage for XenServer. Instead, deploy another UVB and assign storage to the VBA.
- go to the Jobs - Job Manager tab and disable any jobs related to the BDS that is full.
- end any File Level or Instant Recovery restores still running, but not needed.
- use the Recover - Backups tab, use the FILTER BACKUPS to find any Pinned items. This is a lock on the file and prevents purging. Unpin the file, then delete it.
- purge older backups from the system. Using the FILTER BACKUP to choose a To date to define a maximum age you are willing to delete. Delete the backup as needed. It may take several hours (sometimes days) for the purging to complete on a very full system.
