Some of the useful options which can be referenced in the rsync manual. If you run with the ‘n’ option first it will dry run then you can remove the n to do the needful

rsync -navhP --no-compress --ignore-existing --mkpath source dest

-n dry-run, no changes are made -a is for archive, which recursively preserves ownership, permissions etc. -v is for verbose, so I can see what’s happening (optional) -h is for human-readable, so the transfer rate and file sizes are easier to read (optional) -P show progress –no-compress as there’s no lack of bandwidth between local devices

–ignore-existing will skip updating files that exist on receiver -r is recursive, included in -a –mkpath will create the destination’s path component
