Issue



Backup job targeted to Deduplication storage fails with error ""Deduplication Storage Folder 1:1" reported an error on a request to write data to media."


Error



"Deduplication Storage Folder 1:1" reported an error on a request to write data to media."

A backup storage read/write error has occurred.


Cause



Backup Exec does not allow standard software encryption on a job that is being sent to a deduplication folder.  This occurs because data that is encrypted before it reaches the deduplication engine will not deduplicate.


Solution



Backup Exec encryption options should not be used for the backup jobs that are targeted to  Deduplication Storage. Data cannot be deduplicated when it is encrypted.
See related documents for additional information.
