That's ok for me. Probably i'll increase that to 2, but even 1 would be ok

That's wrong.
Ok to remove the "fill" from older backups (according to my
FullKeepCount setting)
but AFAIK, this should remove common files between the filled backup
and the previous one.

A sort of reverse incremental, where the last backup is always a full
copy and the previous
backup is a differential backup storing only different files

Actually is removing the WHOLE backup, making some days unavailable to restore.

Exaclty what i'm trying to understand. If the filled backup is missing, probably
al subsequent unfilled backup would be inconsistent.

Already tried with no luck. BPC is still deleting the whole backup.

v4 is a great software, but actually, is impossible to use.
Probably there is something wrong in my configuration, but i've posted
all customized parameters (mostly the retention levels) to the list
and noone told me about possible issues.
