If your server is configured to wake up at, say 10 p.m. and the
cron-triggered full is already running, it will not start a new
incremental. Triggering the full via cron (before the regular
incremental would start) will give you exactly the behaviour you want.

The trick is that BackupPC _would_ start another incremental because of
the FullPeriod setting, but you interfere slightly before it would do
so. The regular schedule will then notice the running full and not start
another incremental.

HTH,
