Caution when using rsync –compare-dest

This will effectively delete all existing files IF the –compare DIR is the same as dest DIR !!! From Man Page: NOTE: beginning with version 3.1.0, rsync will remove a file from a non-empty destination hierarchy if an exact match is found in one of the compare-dest hierarchies (making the end result more closely match a fresh copy).
