Need to understand the attached snapshot (overwrite & append period)
Please see attached screen shot for properties of 'daily_media set', it says 'overwrite period as 6 days' and for append period 'none, infinite allowed'. This cartridge is of 2.4TB after compression and takes daily differential backups of our servers.
Now from the screen shot, my understanding is the bexec will continue to append until the end of tape is reached and when no space is available to append it will start again from beginning of tape. But this makes any sense to cotinue append? when the overwrite protection is set to 6 days from which I understand that any differential backup on tape will expire after 6 days whether you overwrite or not, is this correct ?
So, I was thinking to change the append period from infinited allowed to 6 days so, it append for 6 days and then again starts from beginning of tape, this makes sense ?
I know the above are easy, but I am in process of understanding this procedure.
