BackupMod vs BtrBack

BackupMod is a free, self-hosted Minecraft server mod for creating and restoring automatic or manual backups. Administrators can schedule several backups each day, check the time until the next run, and set a retention limit that removes the oldest files automatically. Backups can be named, renamed, listed, deleted, or restored by name or as the latest backup. Restoring a selected backup disconnects all players and stops the server. Files and folders can be excluded and later included again. An upload command downloads a ZIP from a direct URL, but Google Drive links do not work. Commands are limited to server operators or authorized players, with normal and detailed logging options. Backups stay in the server’s local backups/ folder. Installation uses the server’s mods folder; Modrinth lists Fabric, dedicated servers, and Minecraft Java Edition 1.21.8–1.21.10.

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`.
