You disturb me ;-) !
I summarize to be sure I understand.
Full : 600 GB
Data modify by day : 10 GB
-------
IncrLevel = 1
M | T | W | T | F | S | S | <- Day
I | I | I | I | F | - | - | <- Backup type
1 | 1 | 1 | 1 | 0 | - | - | <- Level
10| 20| 30| 40|600| - | - | <- DATA COPY BY DAY (GB)
-------
IncrLevel = 1, 2, 3, 4
M | T | W | T | F | S | S | <- Day
I | I | I | I | F | - | - | <- Backup type
1 | 2 | 3 | 4 | 0 | - | - | <- Level
10| 10| 10| 10|600| - | - | <- DATA COPY BY DAY (GB)
-------
With IncrLevel 1, 2, 3, 4 i'm sure that the incrlevel 3 will be not delete if
2, 1 and 0 exist.
With IncrLevel 1, I'm not sure about that...
-------
FullPeriod = 2
IncrPeriod = 8
Also I keep two weeks of backup (and I'm sure no backup will be not delete)

Thanks a lot :-)
