I would find it hard to believe that BackupPC would throttle a production server... Linux usually does a pretty good job of sharing cpu, disk access, network access. And if one process throttles your production server, then you probably have more fundamental issues you need to deal with... > Here are some options I've been thinking about: > > - Backing up / but have most of the large directories and subdirectories > excluded and slowly "unexclude" them one by one in-between full backups.

Have you tried it and run into bottlenecks or are you just worrying in advance? :P ------------------------------------------------------------------------------ Forrester Wave Report - Recovery time is now measured in hours and minutes not days.
