Actually, I don't agree with your maths, sorry :)
The 12th was the 14th day of the retention period.
29th 22:43:13 => start of retention, day/hour 0
30th 22:43:13 => 1st day
31th 22:43:13 => 2nd day
1st 22:43:13 => 3rd day
2nd 22:43:13 => 4th day
...
11th 22:43:13 => 13th day : job could be pruned, and then the volume
12th 22:38 => job is still there, volume is still not recycled ???
So basically it looks more like a Job pruning problem ?

I have 14 volumes : 2 full (1 day per week) + 12 incremental
(6 days per week).
So even if the job stopped one day after schedule (I limit
the job to 20 hours by the way), when the "two week after"
job should takes place (should it be Full or Incr), the volume
should already have been recycled.
That's why I choosed this 13 days Retention time, and not 14.
Or perhaps I am wrong and don't understand some basic thing here ?

I know that, but that's a choice that I have made, I should restrict
the size of backups that I have (more than 6To actually, keeping one
more Full Jobs would mean about 9To...).
