Cause
- This issue occurs if the source volume is full or has lesser than 300 MB of free disk space.
- Drive is too fragmented.
Solution
- Free up 300 MB of disk space on the source volume and then run the backup job again.
(Note: An effective cleanup method is through Windows Disk Cleanup Tool (CleanMgr.exe). If running Windows 2008, this optional feature may need to be installed via a feature called " Desktop Experience". To install, open Server Manager, choose Features, choose Add Feature, then select Desktop Experience to be installed. This will require a system reboot.)
