Delete files from the target directory that have been deleted in the source directory
rsync -avz -e ssh --delete remoteuser@remotehost:/remote/dir/ /this/dir/

Note: the ending {/} is important if you don’t want to hose a directory.

Rsync with a custom ssh port

place the ssh command in quotes; for example:
rsync -avz 'ssh -p1234'

Backup a website on a linux box to your windows machine

rsync reads ":" in a filepath as a remote directory, so if you're trying to rsync to "c://" rsync will be confused. Instead of using windows syntax for filepaths, use the cygwin directory structure.

1. Install cygwin to windows
2. test rsync and ssh are installed by typing from within the cygwin terminal:
rsync --version
ssh -l username somedomain
3. create a directory in c://cygwin named backups or whatever you want to call it.
4. rsync -avz -e ssh --delete remoteuser@remotehost:/remote/dir/ /cygdrive/c/directoryname Change the directory drive to whatever it should be
