InstantBackup vs InvRewind

InstantBackup is a free Minecraft Java dedicated-server mod for incremental world backups. It uses XXHash64 to detect changes and saves only new or modified files. Identical content is shared between backup versions, and blobs are compressed with ZSTD by a dedicated thread pool. Backups can be run manually, scheduled, or managed through an offline command-line interface after the server shuts down. In-game commands create, list, export, delete, and configure backups; every such command requires OP level 2. Scheduling supports intervals, checks whether players are online, and can exclude Carpet fake players. The mod supports Fabric, Forge, and NeoForge for listed Minecraft versions from 1.18.2 through 1.21.11. The default retention cap is 30 versions, while a setting of zero means unlimited. There is no one-click in-game restore: the recommended route exports a ZIP, stops the server, replaces the world directory, and restarts it. The project is licensed under GPL version 3.0 or later, and its listed 1.0.0-beta release is a pre-release.

InvRewind is a free, open-source inventory backup and restore plugin for Minecraft Java servers running Paper, Purpur, or Folia. It can back up player data when players die, change worlds, join, quit, or reach scheduled intervals. Administrators can create backups on demand through a GUI or force backups for one player or everyone. The restore interface can recover selected inventory, armor, offhand, ender chest, XP, or location data, and backups can be exported as shulker boxes. Storage options are YAML, SQLite, and MySQL; the documentation describes YAML for small servers, SQLite for medium servers, and MySQL for large or multi-server setups. Database operations run asynchronously, and Folia region-based threading is supported. Operators can choose fields such as health and hunger and configure per-type retention limits. Scheduled backups are disabled in the example configuration, which shows a 30-minute interval when enabled. The project is licensed under GNU GPL version 3.0 and directs support requests to GitHub Issues.
