Title
Backup fails with the error: "Unable to execute request (122). Unable to query information for the file" -
Description
Backup on one or more DCs fail with an error similar to the following:
"Unable to execute request (122). Unable to query information for the file <pathToAFile>h. The process cannot access the file because it is being used by another process.

Resolution
This error can be an indication that there was something else on the DC trying to access the same file at the same time as when the backup was running and trying to backup the file. Try manually running the backup at a different time than when it ran with the error. If the manually run backup completes successfully, try scheduling the backups to run at a different time.
