Resonator - Modlist Backup and Restore Engine

What is Resonator?

Resonator is built for large, customized MO2 setups. If you’ve ever spent hours rebuilding a broken modlist—or re-downloading a full Wabbajack install—this tool exists to prevent that.  This is not a casual utility. It is designed for experienced users who understand how their modlist is structured and want a reliable way to return to a known working state. The core value of this tool is reliability, consistency, and recoverability , how the tool can create a complete snapshot of your MO2 setup—mods, load order, and overwrite—and lets you restore it back exactly as it was. No rebuilding. No re-downloading. No guesswork.

        Key Features

        Resonator is built on top of Windows-native imaging (WIM), a native feature of Windows, ensuring file integrity and consistency during backup and restore.

        • []Captures your entire mod environment, your mods, profiles, and overwrite folder data, as a single consistent state. No partial backups. No mismatched states.[/]

          []Restore your modlist back to exactly how it was,  No rebuilding.  No re-downloading, and  No guessing what broke.[/]

          []Your current setup is never left in a broken state.  Restore happens in isolation,  only applied after validation, and  automatic rollback if anything fails [/]

          []Every restore is verified against original data. Detecting of corrupted files, and missing files[/]

          []Provides backup & restore report [/]

          []Avoids storing identical data multiple times. WIM possible to store shared assets across mods, only store one physical files.  Can significantly reduce total backup size,  especially effective for large modlists [/]

          []Recover individual mods without full restore [/]

          []Instantly revert your profile configuration[/]

          []Works with deep folder structures and long file paths[/]

          []Built specifically for heavy, customized setups[/]

          Limitation

          []Backup size will not decrease, even if you remove mods from your modlist.  Each backup appends new data. It means previously stored data remains inside the archive.  Over time, backup size may exceed your current modlist size. What to do:  Start a fresh backup in a new folder after major changes[/]

          []Requires additional significant disk space during backup and full restore, especially for large modlists during full restore process for temporary. What to do: remove your MO2 mods folder if you plan to full restore and you have limited free spaces.[/]

          []Works only on Windows systems.  Not compatible with Linux / macOS environments.[/]

          []MO2 must be run as Administrator for backup and restore operations. WIM cannot operate without this access.[/]

          []Not designed for casual modlists.  Overkill for small or simple setups. But the tool still can be used for it.[/]

          []Backups stored on network drives like Google Drive, OneDrive may be unreliable.  Risk of interruption during backup and potential for corrupted backup files[/]

          []Backup storage must support NTFS features[/]
