Hi,

Did you also account that some of the files will still be backupped 
(even when unchanged) as they are also referenced here? :

[ Casino BB | node-10 ] cd /lib/upgrade/keep.d/
[ Casino BB | node-10 ] ls
base-files            netdata               sudo
base-files-essential  openvpn               uboot-envtools
dbus                  opkg
isc-dhcp-server-ipv4  ppp
[ Casino BB | node-10 ] cat *
/etc/config/
/etc/config/network
/etc/config/system
/etc/crontabs/
/etc/dropbear/
/etc/profile.d
/etc/sysctl.d/
# Essential files that will be always kept
/etc/hosts
/etc/inittab
/etc/group
/etc/passwd
/etc/profile
/etc/shadow
/etc/shells
/etc/sysctl.conf
/etc/rc.local
/etc/dbus-1/session.conf
/etc/dbus-1/system.conf
/etc/dhcpd.conf
/etc/netdata/
/etc/openvpn/
/etc/opkg/keys/
/etc/ppp/ip-down
/etc/ppp/ip-up
/etc/ppp/ipv6-down
/etc/ppp/ipv6-up
/etc/sudoers.d/
/etc/config/ubootenv
/etc/fw_env.config

Only "sysupgrade -n" will change this behaviour, but in that case, 
*nothing* is saved at all.
