Keeps a mod's player data safe from modpack updates.
Launchers replace the config/ folder when a pack updates. Dungeon Backup moves a mod's player data out of it, takes rolling zip backups inside and outside the instance, and — if an install ever turns up empty — shows a title-screen card that puts the data back with one click. Restores only ever add files.
Made for Dungeon Train; works with any mod that registers with it. No dependency on Dungeon Train.
Settings: Keep backups (On / Instanced / Off) and Backups per version in the host mod's Options, or config/dungeonbackup-client.toml. Servers: -Ddungeonbackup.backups=off.
Commands: /dungeonbackup backup, /dungeonbackup restore [n].
