There isn't a direct way to do this.  You can spread
BackupPC_nightly's job over several nights (ie: less done each
night) with $Conf{BackupPCNightlyPeriod}.  You could also increase
$Conf{MaxBackupPCNightlyJobs}, but I doubt that's a good idea if
your server is already very busy.

Could it be that you are now backing up more data than before, and
your overall server capacity is no longer sufficient?
