I believe you can 'protect' images from modification by making a
duplicate. That will create a group with the new duplicate as the
front member, which will receive all modifications unless the group is
opened and another member is selected.
This way any accidental change will hit the dummy front member of the
group.
I don't know how fool proof this will be, but maybe the devs can
comment on the virtues and vices of this method.

My strategy is to backup all .xmp files before starting a session and
sometime in the middle. In my collection which is now around 100G the
compressed file with all .xmp is less than half megabyte. I use this
script:
#! /bin/bash
#
# create a copy of all xmp source files in my dirs
#
out_file_name=allxmp-$(date +"%Y-%m-%d_%H-%M")
cd ~
rm -rf tmp/$i{out_file_name}.lst
find . ./Pictures/ -iname "*.xmp" > tmp/${out_file_name}.lst
tar cz -T tmp/${out_file_name}.lst -f
management/safebackups/${out_file_name}.tar.gz
echo DONE, file is ${out_file_name}.tar.gz
ls -l management/safebackups/${out_file_name}.tar.gz
...hope this helps.
