BtrBack vs InvRewind

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.

InvRewind is a free, open-source inventory backup and restore plugin for Minecraft Java servers running Paper, Purpur, or Folia. It can back up player data when players die, change worlds, join, quit, or reach scheduled intervals. Administrators can create backups on demand through a GUI or force backups for one player or everyone. The restore interface can recover selected inventory, armor, offhand, ender chest, XP, or location data, and backups can be exported as shulker boxes. Storage options are YAML, SQLite, and MySQL; the documentation describes YAML for small servers, SQLite for medium servers, and MySQL for large or multi-server setups. Database operations run asynchronously, and Folia region-based threading is supported. Operators can choose fields such as health and hunger and configure per-type retention limits. Scheduled backups are disabled in the example configuration, which shows a 30-minute interval when enabled. The project is licensed under GNU GPL version 3.0 and directs support requests to GitHub Issues.
