I'm using below command to transfer files cross server

scp -rc blowfish /source/directory/*

Is there a way to transfer only files modified files just like update command for cp?

rsync is your friend.

rsync -ru /source/directory/*

If you want it to delete files at the destination that no longer exist at the source, add the --delete option.

Although, if you are syncing to a web server and that server caches HTML, you might not want to use --delete, since visitors on a stale page might request an asset that no longer exists. – Jackson May 24 at 21:56
