ChronoVault Backup vs FastBack

ChronoVault Backup has no write-up on Specifiction yet; its figures are above.

FastBack is a free, open-source Minecraft mod for incremental world backups: snapshots save changed parts rather than the entire world. Backups can be stored locally, on a Git server, or on a network volume without a Git server. They can run when a world shuts down or after Minecraft autosaves. Restoring a snapshot creates a copy of the selected world, leaving the current files untouched. Snapshot pruning and retention policies help manage backups, which can also include mod JARs and configuration files. FastBack works with Minecraft clients and dedicated servers on Linux, Mac, and Windows. It requires native Git and Git LFS to be installed and available on Minecraft's process PATH. The project describes it as intended for worlds up to about 5GB and recommends GitHub remotes only for smaller worlds under 500MB because of GitHub size restrictions. Documentation links to CurseForge for downloads and Discord for questions and help installing native Git. FastBack is distributed under GNU GPL version 2.
