InstantBackup vs ServerBackup

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.

ServerBackup is a Minecraft server backup plugin for administrators seeking to protect server files and worlds from data loss, griefing, and chunk failures. It schedules backups automatically and offers in-game commands to target a particular world, folder, or file. Those commands can also list and search backups, remove them, and zip or unzip folders. Backup creation runs asynchronously, separately from the server’s main thread. Dynamic Backups are designed to save only world chunks or regions that may have changed. The plugin can upload and download backups through an external FTP server and list remote backups; the maker says transfers use SSL encryption. A configuration setting can delete local backups after upload. Many settings are customizable through config.yml. ServerBackup is free, with Linux and self-hosted platforms listed. The homepage offers version 2.10.0 for Minecraft 1.18 and later, plus an alternate version for earlier releases. SFTP on port 22 does not work with its FTP backup feature.
