aw-Autosaver from MotionLand replaces the standard After Effects auto save with a version-based backup panel. It can save .aep backups automatically or manually to any location, and you can choose to save only the project copy when a full backup isn't needed.
The panel lets you monitor the number of versions and set a custom auto save interval and version count. Alt+Click adds a comment to a version, and single-click buttons open the project's folder or the versions folder directly. Beyond the main backups, it can save a project copy in an individual folder and keep an auto backup of the versions folder. The UI is customizable.
Version 2.1 fixed a licensing framework issue, and the listing was last updated on January 8, 2025. It runs across a wide range of hosts, from After Effects CS6 through 2025, and a demo video is available. In this catalog it's listed as free; check the developer's page for current licensing.
