I believe it will transfer everything for each full backup. You can specify lists of files to exclude; I would suggest that you only back up home directories, but make sure you and your users understand all the implications of that > - If it does, is it the same with Rsync ?

Probably - but it depends on whether your important data has resource forks or not. my limited experience is that most data files don't use resource forks any more. But MOST does not mean ALL. :) You may want to try this: http://www.quesera.com/reynhout/misc/rsync+hfsmode/ I have not tried it with backuppc.

It is possible. Make sure you understand what each incremental backup backs up, though. Read the "Incremental backup" section of the faq at: http://backuppc.sourceforge.net/faq/BackupPC.html in short, there are multiple levels, and each level backs up the things changed since the previous higher-level backup. you may want to do something like yearly full monthly level 1 weekly level 2 monday level 3 tuesday level 4 wednesday level 5 thursday level 3 friday level 4 In practice, I would watch the amount of data sent on incrementals and adjust the schedule accordingly. If you want to get really tricky, search for "towers of hanoi" backup scheduling. > Many thanks for your help, and sorry for languages mistakes, english > is not my primary language, doing my best ;) Your English is 1000x better than my French (guessing from your name that is what you speak natively). danno ------------------------------------------------------------------------------ Beautiful is writing same markup.
