InstantBackup vs Simple Backup

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.

Simple Backup is a free, open-source utility for Minecraft Java server worlds. It schedules automatic backups at configurable intervals and can save them as ZIP archives, TAR.LZ4 archives, or direct directory copies. Backup jobs run asynchronously, and automatic runs can pause when no players are online. Configuration can cap the number of retained backups and stop a new backup when available disk space is too low. Server operators can start backups manually with commands for a general run, ZIP, LZ4, or directory output; the required permission level is configurable and defaults to level 4. Backups are stored in a `backup` folder in the game directory unless an absolute system path is configured. The mod runs only on the server, requires Fabric API, and lists Fabric and Quilt loader support. ZIP uses deflate level 5, while LZ4 files use `.tar.lz4` and need two extraction steps. Support is provided through a GitHub issue tracker.
