I did update the program and received the same error. However, I noticed on the d: partition there were some image backup files stored there from a third-party backup program.  Once I deleted those, the backup completed without error.  Best regards, -Jim
[IMAGE] Hello: I have a Dell OptiPlex 3020 MT that has an external hard drive dedicated to backups.  It has about 700 GB of free space.  I tried to perform a system backup and it gets about one third from completing when I receive this error message: Operation Cancelled. Destination location unavailable or not enough space on the disk. I have inserted a screen capture of this error.  I am using the latest version of B&R. Can you assist me with this error? -Jim
