I set FullPeriod to 7.1, which should also work. I also kept IncrKeepCount at 6.
I'd like to autoexpire the full backups, but BackupPC's mechanism won't cut it. So, until I can do it automatically, deletion of fulls will have to be done manually.
Will putting FullKeepCnt=300 suffice for never having BackupPC delete fulls?
I might end up doing archives after the backups complete. That I should be able to automate.
