MS SQL, Exchange or Files and Folders backup completes with the following error: 'The system cannot find the file specified.'
Backup session ends with the status "Completed with errors" because there is not enough available space for creating a snapshot.
Right-click on C:\ drive >> go to Shadow copies tab>> check the snapshot limitations (or right-click on drive >> Configure shadow copies, depending on the OS) and increase the snapshot storage limit, or run this command from the command line: vssadmin list shadowstorage (http://technet.microsoft.com/en-us/library/cc788050.aspx )
You can also check to see if you still have undeleted snapshots created by another program with 'vssadmin list shadows' command (http://technet.microsoft.com/en-us/library/cc788116.aspx ) and they are taking up all the space reserved for snapshots.
