You should also consider setting the --delete flag (deletes file in backup when deleted on your root filesystem and --delete-excluded which will delete the files you have excluded in your backup. I also exclude /var/cache and /var/run

To avoid having to re-install the system if the SSD collapses one day, I wanted to make a simple back-up copy of vital files on the HDD. I recently installed an SSD to replace three SCSI drives and changed my backup at the same time to work llike this. But I just do everything except /home, /encfs, the mail spool dir, etc. I also use a spare IDE drive for a system backup which I manually rsync before a big emerge, so I can boot the backup if the main system no longer boots due to emerge screwup. I have some other changes to make before testing this. What I haven't figured out yet is how to reverse rsync the backup to the main system. Rsync has no --source-is-always-right option that I could find. cp -a might work, with a little care for /dev etc, but it won't delete destination files which aren't in the backup, and the idea of reformatting the system partition as part of this seems a bit extreme when rsync is the natural choice for restoring the backup. -- ... _._. ._ ._. . _._. ._. ___ .__ ._. . .__. ._ .. ._.
