I think I am getting somewhere with the syntax of the rsync command
line, I am trying the following
-vv verbose
-g preserve group
-W send whole files
--exclude-from=$EXCLUDES
the last is one I'm not sure of, does the 'exludes' apply at both ends?
I have created an 'excludes' file listing certain files in the local
database which I don't want copied to the remote database, but I don't
want to delete any files with same names in the remote database.
or should I use?
--n--delete

Presumably the checksum calculated by 'sha256sum -b * sha256sum.txt'
will only be valid so long as the original files have not been amended,
so only of value one time
