Advanced Backups vs ServerBackup

Advanced Backups is a free, open-source backup mod for Minecraft Java edition, supporting NeoForge, Forge, Fabric and Spigot. It can run entirely on a server; a client installation is needed only to receive backup notifications. The mod supports ZIP, differential and incremental backups, with options for schedules, startup and shutdown backups, and minimum and maximum intervals. Automatic purging can be set by storage size, age or backup count, while command-created snapshots are protected from that cleanup. A command-line tool can restore a whole backup or an individual file and export a backup; it requires Java on the system PATH. The tool can detect backups created by other mods, but it cannot export those backups. Client-side toasts report when backups occur and can be disabled or limited to operators. The README says many Minecraft versions are supported and invites requests for additional versions. The project lists a BSD-3-Clause license, and its backup scope is worlds-only with local storage. One limitation matters for incremental backups: losing a partial backup can damage that chain until the next full backup, and incremental restores take the longest.

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.
