I think you have a fundamental misunderstanding of what BackupPC does and what it is used fo. BackupPC is for *file* level backups. It could technically do what you want but then you would just be backing up a single file every night. Since on a running PC it is certain that at least one byte will change day-to-day somewhere on the disk, that means that you will have no effective pooling (which is the major advantage of BackupPC) and you will be storing complete (compressed) images of each and every backup. You may get some bandwidth savings in the transfer if you use rsync/rsyncd but that will have nothing to do with BackupPC. Why would you go through all the overhead of BackupPC just to rsync a single file every day? Just use cron + rsync. If you are looking for file level diffs then you need something altogether different... ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
