We are running backup on a server with active deduplication to keep the size of the files to a minimum. Everything work fine until we try to take a differential backup of the original file. ( the original file is duplicated at this moment )
We get the following error right after the backup start :
! Error reading the file: Abort (auto)
! Creating differential backup read object failed with code 0x2b810000, Read from disk failed
! Extended file info: (1) \\Deduplicated_Server\File.arc
! Operation failed: Write to disk failed (error #3053)
We can restore data from the original file and the Verify backup command give us no error.
Do R-drive support deduplication for differential backup ?
Thank for the help !
