BtrBack vs ServerBackup

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.

ServerBackup is a Minecraft server backup plugin for administrators seeking to protect server files and worlds from data loss, griefing, and chunk failures. It schedules backups automatically and offers in-game commands to target a particular world, folder, or file. Those commands can also list and search backups, remove them, and zip or unzip folders. Backup creation runs asynchronously, separately from the server’s main thread. Dynamic Backups are designed to save only world chunks or regions that may have changed. The plugin can upload and download backups through an external FTP server and list remote backups; the maker says transfers use SSL encryption. A configuration setting can delete local backups after upload. Many settings are customizable through config.yml. ServerBackup is free, with Linux and self-hosted platforms listed. The homepage offers version 2.10.0 for Minecraft 1.18 and later, plus an alternate version for earlier releases. SFTP on port 22 does not work with its FTP backup feature.
