rsync-deploy : How to deploy only files that have changed?

Question

My pipeline deploy all files. I want it to deploy only files that have changed. I added '-u' option in 'EXTRA_ARGS', but it didn't work. Here is my code.

- step:
    name: Test Deploy
    deployment: Test
    script:
       - pipe: atlassian/rsync-deploy:0.5.0
         variables:
           USER: $RSYNC_USER
           SERVER: $RSYNC_SERVER
           SSH_PORT: $RSYNC_SSH_PORT
           REMOTE_PATH: '/home/myname/public_html/'
           LOCAL_PATH: '${BITBUCKET_CLONE_DIR}/html/'
           DEBUG: 'true'
           DELETE_FLAG: 'false'
           EXTRA_ARGS: '-uv --exclude=.htaccess --exclude=.htpasswd --exclude=.env'

Am I missing something?

I resolved my issue with thesw flags -c (checksum) and --update

EXTRA_ARGS: '-c --update ${BITBUCKET_CLONE_DIR}/'

Try maybe this one below

EXTRA_ARGS: '-uv -c ${BITBUCKET_CLONE_DIR}/html/ --exclude=.htaccess --exclude=.htpasswd --exclude=.env'
