I've added a "BlackoutFulls" config option to my local copy of BackupPC. This functions in a similar fashion to BlackoutPeriods but is only checked when BackupPC has determined that a full backup needs to be done (and was not requested by the user). I've configured my system so that incrementals are blacked out during day on the weekdays (Mon-Fri) and fulls are blacked out except on the weekends.
I have not completed the localization (string is added to all files, but not translated from english) and I'm not sure how to add documentation so I could use some help.
If this is something that the community would like added to BackupPC, I need to know how to submit my changes.
Regards,
Brad
