lsyncd

Watch files and directories and run rsync when they change. It is often used to keep two directories on separate systems in sync, ensuring that changes made in one directory are immediately mirrored to the other. More information: https://github.com/lsyncd/lsyncd.

• Watch the source for changes and run rsync to synchronize files to the destination on every change:

lsyncd -rsync path/to/source host::share_name

• Use SSH instead of rsyncd shares:

lsyncd -rsyncssh path/to/source host path/to/destination
