What Simple Backup is
Simple Backup is a free, open-source utility for automatic backups of Minecraft Java server worlds. Operators can schedule backups at configurable intervals and choose ZIP archives, TAR.LZ4 archives, or direct directory copies. Backups run asynchronously to reduce their effect on game performance, and scheduled runs can pause when no players are online. Configuration can cap the number of retained backups and block new backups when available disk space is too low. Manual commands include `/simplebackup start`, `/simplebackup zip`, `/simplebackup lz4`, and `/simplebackup directory`; the permission level is configurable and defaults to level 4 for operators. Backups are saved in a `backup` folder in the game directory unless an absolute system path is configured. The mod is installed only on the server and requires Fabric API. The project lists Fabric and Quilt loader support. ZIP uses deflate compression at level 5, described as slower to compress than LZ4. LZ4 output uses `.tar.lz4` and requires two extraction steps to recover files. Support is provided through a GitHub issue tracker.
