AutoBackupV2 vs BtrBack

AutoBackupV2 has no write-up on Specifiction yet; its figures are above.

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`.
