Ugh, missed that. I thought that past FullAgeMax, only
FullKeepCntMin mattered. In fact, I thought that was the *point* of
FullKeepCntMin.

read the comments in config.pl or the source of BackupPC_dump if you want the

No.

Why don't you simply set FullKeepCnt to the number of backups you want to keep
(which appears to be about 16)?
Hope that helps.

I want it to delete all the fulls older than 60 days.
FullKeepCntMin is only 5, so if I have more than 5 fulls (which I
do), then everything older than FullAgeMax should be deleted, no?

Where is your problem? You have 22 full backups already achieved. So your
server will also keep the next 3 full and will remove the #0 since the 4.
full backup will occur.
The count of already achieved incrementals is 45. Exactly what you want.
