2. What files should NOT be backed up on a Debian Linux machine?
I originally set BackupFilesExclude = /proc, /mnt, /dev, /cdrom, /floppy, /lost+found, /media, /var/lib/backuppc, and then started a full backup. I got lots of errors (~10,000), and the log file shows most of them (all - too many to count!) were confined to /sys. Should /sys be excluded as well? I am not enough of a Debian/Linux guru to know if this is a directory I should exclude or not. It seems that it should be excluded based on what I have read about it, but I just wanted to check with the experts. Are there any other directories that should be excluded from a "normal" Debian installation? Some of the machines are servers for tomcat/apache, some are desktop machines running X.
You should also exclude /tmp and /sys. You should think about whether or not you want to be able to completely restore the debian system from backuppc or if it is ok to reinstall the system and restore /etc.
3. Are there any Windows directories that should be excluded from a backup? The Windows machine is not a server, just a desktop with users.
Because you cannot restore a windows system you should exlcude everything except the "Documents and Settings" and any other directories you store specific data in. Since it is not a server, I dont think you would have anything like mysql or anything like that.
I would also add something like c:/backup and they run a script on the windows machine to save the registry into that folder just in case.
