BtrBack vs MineBackup

BtrBack is a Minecraft Java server plugin for making and restoring full-server backups with Btrfs snapshots. It stores backups locally, supports scheduled backups, and uses a custom retention policy. Operators install the plugin in the server’s plugins folder and use `/btrback [backup/rollback]` to create a backup or start a rollback. Normal backups appear in the `backupSnapshots` section of `backups.json`. Before a rollback, the plugin also snapshots the current server state and records it under `rollbackSnapshots`, outside the regular backup list. Restoring a backup reboots the server twice: once to restore the saved state and again to start normally. Setup requires placing the server directory in a Btrfs subvolume and mounting the root subvolume with `user_subvol_rm_allowed`. The public repository includes the Good Luck With That Public License, which permits copying, distribution, modification, merging, selling, publishing, and sublicensing at the user’s own risk. The repository page shows no releases and zero open issues. The listed plan is free at free.

MineBackup is a free, open-source GUI program for backing up and restoring Minecraft saves, and it can also back up any folder on a PC. It offers Full backups and Smart incremental backups, which are intended to reduce time and storage use. Users can restore from a local backup or a .7z archive, with compression handled by a built-in 7-Zip core. A hotkey can trigger a live backup, and exit detection can start one when Minecraft closes. First-run setup can discover supported game locations and launcher data, including HMCL, Prism Launcher, and Modrinth App. KnotLink lets mods or other tools request a save before backup; hot restore requires the MineBackup companion mod, version 3.0.0 or newer. A headless CLI can create Full or Smart backups, verify archive chains, and perform confirmed cold restores. Server packages are available for Windows and Linux, with scheduling guidance for systemd on Linux and Task Scheduler on Windows. Desktop releases list Windows x64, Linux x86_64, and Apple Silicon macOS 15 or later. The project directs bug reports and feature requests to GitHub Issues. Smart incremental detection is not guaranteed to catch changes that preserve both file size and modification time.
