I've got six B2D Jobs to do full backups every night. All jobs are writing concurrently to the same B2D folder. This works really fine for me.
I've had a single job before but the daily backup took way to long. So I've decided to split the job into multiple jobs.
For every B2D job I've a duplicate job which starts when the associated B2D jobs finishes.
The duplicate jobs are writing to a Dell Powervault 132T library with one sdlt 320 drive. The whole amount of our data fits on three sdlt 320 tapes.
Now my problem is that only three dupilcate jobs running successful. The first three jobs are writing one after another to each of the 3 tapes I've loaded in my library. One jobs stays queued and waits for an overwritable media to be inserted and the other two jobs are waiting for the device.
How can I accomplish that all six duplicate jobs are writing only to the three tapes.
I've set overwrite protection period to 6 days and append period to infinite.
In the duplicate job propterties under device and media I had "overwrite media" selected, not "append to media, overwrite if not appendable media is available"
