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.
