Hi,
I'll try to answer your questions:
First let's make sure that there *is* a problem. In some commands
below you may need to change the logged-in user ID to one which can
read the necessary files (often, for example, to user 'backuppc'). --->
Sorry I don't know how to check this, user is running backuppc is backuppc
and seems ok, any other check?
1.
Did you run BackupPC_nightly by hand?
How many times has it been run on the nightly backup schedule since
your most recent install of BackupPC version 4?
I have forced executed multiples times changing time, and now after 7 day
seems that some files were purged but not all because I have a
retention full 2 days and incremental 1 day

It seems that no tall backups are purge, I suspect...
