it does usually!

you can force --checksum as param
-c, --checksum  skip based on checksum, not mod-time & size

but that does not change the fact that it syncs attributes too
without --checksum, i am using --checksum once per month to
make sure all is 100% consistent

rsync --help
man rsync

there are really A LOT of parameters

--dry-run as first one to test what happens in combination
with --progress / --verbose

"--times --update --perms --owner --group" without delete is
my favorite if i have to make small changes on php-modules to sync
back only my changed files and prevent overwrite files in upload-areas
while the worst-case here is that i push back a deleted file but users
not often delete anything :-)

"--exclude=folder1 --exclude=folder2" is also nice

-W, --whole-file copy files whole (without delta-xfer algorithm)
amkes sometimes sense if the checksum stuff is overhead for sure

--exclude=PATTERN       exclude files matching PATTERN
--exclude-from=FILE     read exclude patterns from FILE

 -b, --backup                make backups (see --suffix & --backup-dir)
     --backup-dir=DIR        make backups into hierarchy based in DIR
     --suffix=SUFFIX         set backup suffix (default ~ w/o --backup-dir)

finally: a swiss knife for dealing with file transfers
