This one replicates all from /200gb/DOCS to the server called “sol” and removes files in “sol” that we deleted locally. the
“c” is for checksum, the “t” is for updating
rsync -crtva –delete /200gb/DOCS/ root@sol:/200gb/DOCS/
if we want to copy locally from /a to /b, but never change /a
rsync -crtva /a/ /b/
