Minecraft overview

Choose Minecraft save protection and understand bundled MineRewind, game-side components, hot backup, regions and map preview.

FolderRewind 1.9.6 uses MineRewind v3. FolderRewind 1.9.6 bundles released MineRewind 1.9.8, requiring API 3.9; game-side mods/server plugins have independent versions. Actual game loading still needs separate validation.

Components​

FolderRewind owns configuration/history/archives/cloud/Safe Restore. MineRewind supplies instance discovery, scopes, consistency, metadata, coordination and staging proposals. MineBackup-Mod/MineBackupPlugin saves/freezes/exits game worlds; Death Rewind/JEA request operations through game-side APIs.

Single-player/LAN owner, modded dedicated servers and Spigot/Paper have different exit/rejoin semantics. Server Sidecar does not reconnect clients automatically. Consult component release matrices.

Setup and discovery​

Install a trusted .frplugin and explicitly enable it. Static defaults: AutoDiscoverSaves=true, AutoCreateConfigs=false, PreservePlayerData=false. The old EnableHotBackup switch is absent in v3. Review per-instance drafts/Kind/paths before creation; plugins do not save Host configs directly.

Live operations​

Active worlds use held session.lock. Backup consistency leases coordinate saves/stable sources: Prefer may degrade with warnings; Require blocks unavailable consistency. Restore coordinates writers and cannot silently bypass required providers.

Alt+Ctrl+S/Alt+Ctrl+Z request backup/Quick Restore. The Host resolves the active branch's unique local tip, not a guaranteed previous time. KnotLink supports seven current_save selectors inheriting core arguments.

Players and regions​

Ordinary Restore can preserve selected NBT fields for all UUIDs; stats/advancements still restore, cross-26.1 preservation blocks, and Checkout/Merge do not preserve players. Region areas use block coordinates and partial captures force Overwrite; see regions.

Start with setup, hot backup, hot restore and troubleshooting.

MineBackup-Mod

The in-game integration mod coordinates saves, exits, hot backup, hot restore, and automatic rejoin.

Java, Bedrock and ordinary directories​

MineRewind 1.9.8 extends launcher and Bedrock discovery; see quick start. Java worlds, Bedrock worlds and ordinary configuration folders differ: Java may use its coordination, NBT and region capabilities; Bedrock uses a separate Kind with ordinary file handling and requires the game to close; ordinary directories skip optional world metadata capture. Successful discovery does not certify actual game loading.

Minecraft Merge uses the Host's conservative file-level three-way merge, without region/chunk/NBT semantic merging.

Bundled and separate releases​

FolderRewind 1.9.6 bundles MineRewind 1.9.8 (API 3.9). The separate plugin Release and official catalog currently provide 1.9.5 (API 3.6), without map preview. Replacing the bundled version with that older package will not add new features. See read-only preview for the Java map.
