Advanced Backups vs Simple Backup

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.

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.
