I've done this with rsync, but I only synchronized configuration files:
#!/bin/bash
eval "$(emerge info | grep CONFIG_PROTECT)"
set -x
rsync -e 'ssh' -CavP --stats \
$( for d in ${CONFIG_PROTECT}; do
[ -e ${d} ] && echo --include ${d}/
done) \
--include-from /etc/syncconfig/include \
$( for d in ${CONFIG_PROTECT_MASK}; do
[ -e ${d} ] && echo --exclude ${d};
done) \
--exclude-from /etc/syncconfig/exclude \
--exclude '/*' \
--backup --backup-dir /var/config/$(date '+%Y-%m-%d') \
--delete --delete-after / ${1}:/
This leverages CONFIG_PROTECT and CONFIG_PROTECT_MASK from Portage,
plus has two additional files to list manually excluded or included
files, and keeps old configuration files in /var/config on the
destination.
