Backups fail with Low disk space errors even when the Dsstat output shows enough space available within containers, but windows reports free space less than 15%

Error Message

Final error: 0xe00084ec - A backup storage read/write error has occurred.

If the storage is tape based, this is usually caused by dirty read/write heads in the tape drive. Clean the tape drive, and then try the job again. If the problem persists, try a different tape. You may also need to check for problems with cables, termination, or other hardware issues.

If the storage is disk based, check that the storage subsystem is functioning properly. Review any system logs or vendor specific logs associated with the storage to help determine the source of the problem. You may also want to check any vendor specific documentation for troubleshooting recommendations.
