Media Pool Retention, how to calculate

[Jackobli]

Hello again
We're running slowly out of tapes and are unsure how the retention has to be calculated

Retention = 4 weeks
Allocation = fri, 20:00h
backup-jobs

1. Starting with Fridays, full backup (needs two tapes, runs until Sunday morning)
2. Starting with Sundays until Thursday = latest only

So I think, on the fifth Friday the first set should expire? But actually, I still see this tapes with Status "full".
Or is this calculated on the date of the last use? Then it would perhaps expire this weekend.

Regards, Urs

Like to (partially) answer to myself
So the tapes have expired, dunno if yesterday (Saturday) or today (Sunday), just have seen it now (on Sunday).
Under «Content» the backup is still visible, I think it will disappear as soon as one (or the first) of the now retired tapes are getting reused?
