FolderRewind vs InstantBackup

FolderRewind is a free Windows application for backing up and restoring files, project data, and game saves. It offers full, smart incremental, and overwrite backups using 7-Zip, with 7z and zip compression and configurable levels, methods, and thread counts. The home page says encrypted backups use AES-256. Automation can run at intervals, on a schedule, at startup, for selected targets, or when conditions are met. FolderRewind uses rclone to transfer local backup chains to cloud storage as an extra redundancy layer; its guide demonstrates OneDrive setup and mentions WebDAV bridges such as OpenList. The official MineRewind extension adds Minecraft save discovery, hot backup and restore, hotkeys, and coordination with the current world. Restoring partial backups forces Overwrite and disables Clean to prevent removing files outside the backup scope. Requirements are Windows 10 version 1809 or later, or Windows 11, on x64 or ARM64. The maker recommends Microsoft Store; MSI is marked beta and MSIX is offered for advanced sideloading.

InstantBackup is a free Minecraft Java dedicated-server mod for incremental world backups. It uses XXHash64 to detect changes and saves only new or modified files. Identical content is shared between backup versions, and blobs are compressed with ZSTD by a dedicated thread pool. Backups can be run manually, scheduled, or managed through an offline command-line interface after the server shuts down. In-game commands create, list, export, delete, and configure backups; every such command requires OP level 2. Scheduling supports intervals, checks whether players are online, and can exclude Carpet fake players. The mod supports Fabric, Forge, and NeoForge for listed Minecraft versions from 1.18.2 through 1.21.11. The default retention cap is 30 versions, while a setting of zero means unlimited. There is no one-click in-game restore: the recommended route exports a ZIP, stops the server, replaces the world directory, and restarts it. The project is licensed under GPL version 3.0 or later, and its listed 1.0.0-beta release is a pre-release.
