Backup job failing with no appendable media error
One of my clients backups has started failing just recently with error "Drive and media mount requested date Media mount failed". Nothing has changed in the setup of the backup job and the tape should have plenty of space left to complete the job. I am also seeing the error "No appendable media could be mounted. Switching to overwrite operation on scratch media".
I'm at a loss to explain why this is happening. I have an Erase Tape job that runs just prior to the Backup job but in the past this has worked fine. The tape is an LTO 4 with hardware compression enabled and I get about 600GB on the tape before it produces the no appendable media error. The job is also set to append, overwrite if no appendable media is present. Like I said, this has not been an issue in the past.
Can anyone help as to why this could be happening??
