rsync file selection

How does rsync determine which files need to be updated? By default, any file that is a different size or has a different modification time between the source and destination will be updated with rsync.

There are four options which change this behavior:

-I, --ignore-times
--size-only
--modify-window
-c, --checksum

See rsync(1) for more information on these options.
