Yesterday I came across a problem to sync files between two computers in a network, but only those that had been created or modified within the last 60 days. Unfortunately rsync doesn't come with such a functionality (or it doesn't seem to - maybe I've overlooked something). It could well be that I've gone to work in a more complicated manner than necessary but I couldn't come up with anything better.
So I took the extra step to copy the files that need to be synchronised to a temporary directory, preserving the original directory structure. Then the files can be effortlessly synced with rsync.
Maybe this will come in handy for somebody else.
