Full Filesystem rsync
Sometimes we need to move an entire server from one machine to another machine.
The first step is to boot the target guest from a debirf image, mount all filesystem in /mnt, and add the source server's ssh key into /root/.ssh/authorized_keys on the debirf image.
Then, on the source, edit and run the following script:
# make sure all the remote filesystems are properly mounted under /mnt target=root@leslie.new:/mnt # all user/system non-temporary filesystems on the origin server: originfilesystems="srv var home" # -a typically means: --recursive --links --perms --times --group --owner --devices --specials # we don't use extended attributes normally (otheriwse, we might want -X) # or ACLs (otherwise might consider -A) exclude="--exclude /etc/fstab --exclude /etc/network/interfaces --exclude /etc/udev/rules.d" rsync -ax --hard-links --delete ${exclude} / "${target}"/ for fs in ${originfilesystems}; do echo "transfering filesystem from /${fs}" rsync -ax --hard-links --delete /${fs}/ "${target}/${fs}/" done
