Up until now:A volume/tape will be reserved by a job to write when
A tape received "Recylable" status when
NEW:An expired tape is not considered for writing any longer -AND-it will in that case be set to "Recyclable" regardless of its "Full" or "Closed" state. Not changed:A tape will be recycled depending on the chosen pool policy. "Greedy" will recycle tapes as soon as they receive the "Recyclable" status. Otherwise, empty tapes will have preference.Rationale:This is the easiest and most understandable way to ensure that "Progressive" backup while doing retention saves those files that need to be re-saved on a new set of media.For the other backup strategies, this does not have any adverse consequences. On the contrary, it ensures that the next backup has more space to save its data. The only conceivable drawback is that expired data may now be deleted earlier than it had been previously. | |
