After 3.5 years of work ELS 4.0 has been released 
ELS is a free purpose-built library-oriented data management and back-up tool that is both a desktop application and command line tool. It supports expandable storage spanning multiple devices.
ELS may be used on a “workstation” to aid in the creation of new content that is copied to a media or data server. Used on a server (publisher) containing a media or data “collection” for maintenance and back-up to one or more “subscribers”. And may be used on subscribers, even for bi-directional back-ups.
Any project with large amounts of data for home videos, YouTube, TikTok, Instagram, game development, 3D modeling, science, or media systems such as Plex and Jellyfin, organizing and managing your work is important. And backing it up is critical.
Several tools are included that may be combined into Jobs to automate a sequence of Tasks.
ELS can operate locally or over a LAN or the Internet. Runs on Linux, Mac and Windows.
