Resolution



To resolve this issue a reset of the DPX Change journal on the volume in question is required in order to do this please follow these steps: 

How to reset Change journal on drive for DPX:
- Open a DPX command prompt in Administrator mode ( right click run as administrator) on the failing server.
- Run disklist.exe from the DPX tools directory 
- Look for the volume serial number that is failing in the job log and note the drive letter it is associated to 
- Start bexsnapmgr.bat 
- Select Change journal configuration 
- Select the <insert drive letter> and press disable 
- There is no need to enable it again as the first backups will automatically perform this operation 
- Run the backup twice to make sure a new base is created and the next incremental runs correctly
