Modding can completely transform a game. It can add new content, fix bugs the developer never patched, improve graphics, or turn a familiar experience into something entirely fresh. But modding can also break your game beyond repair if something goes wrong, and something goes wrong more often than most guides will admit.
A proper backup is the difference between a five-minute recovery and losing dozens of hours of progress. This guide covers every method, every platform, and every situation so that no matter what you are modding, you know exactly how to protect yourself before you touch a single file.
Why Backing Up Before Modding Is Non-Negotiable
Most people skip backups because they assume the mod will work fine or that they can reinstall the game if something breaks. Both assumptions are dangerous.
Here is what can actually go wrong when you mod without a backup:
- A mod can corrupt your save file permanently, making your progress unrecoverable even after uninstalling the mod.
- Some mods overwrite core game files with no option to restore them through the launcher.
- Mod conflicts between two seemingly unrelated mods can cause crashes that only occur hours into gameplay.
- A failed mod installation can break the game’s verification system, making it impossible to repair through Steam or other platforms.
- On consoles, unauthorized modifications can trigger account flags that affect online access.
None of these scenarios can be recovered without a backup. With one, every single problem on this list becomes a five-minute fix.
Understanding What Needs to Be Backed Up
Not everything in your game folder is equally important. Knowing what to back up helps you work faster and store files more efficiently.
Game Save Files
These are your most critical files. Save files store your progress, character builds, unlocks, and game state. Losing them means starting over completely. They are usually stored separately from the game installation itself and need to be backed up even if you are not touching the game files directly, because some mods interact with saves on installation.
Game Installation Files
These are the core files that power the game, including executables, assets, configuration files, and scripts. Mods typically modify these directly. If a mod overwrites a core file and something breaks, you need the original to restore from.
Configuration and INI Files
These store your graphics settings, keybindings, and gameplay preferences. Many mods edit these automatically. Without a backup, you may lose your entire custom setup and have no way to know the original values.
Mod Manager Profiles and Load Orders
If you use a mod manager, your load order, profile settings, and plugin list are just as important as the game files themselves back these up separately so you can restore a working configuration instantly.
How to Back Up Your Game on PC
PC gives you the most control and the most options. Here are all the methods available, from the simplest to the most thorough.
Method 1: Manual File Copy
This is the most reliable method because it requires no software and works for every game on every platform.
Step 1: Locate your game installation folder
For Steam games, the default location is usually:
- C:\Program Files (x86)\Steam\steamapps\common\YourGameName
For Epic Games, the default is usually:
- C:\Program Files\Epic Games\YourGameName
For GOG games, the default is usually:
- C:\Program Files (x86)\GOG Galaxy\Games\YourGameName
Step 2: Locate your save file folder
Save files are rarely stored inside the game installation folder. Common locations include:
- Documents\My Games\GameName
- AppData\Local\GameName
- AppData\Roaming\GameName
- AppData\LocalLow\GameName
- C:\Users\YourName\Saved Games\GameName
To find AppData quickly, press Windows Key plus R, type %appdata% and press Enter.
Step 3: Copy both folders
Right-click the game installation folder and copy it to an external drive, a second internal drive, or a clearly labeled folder on your desktop. Do the same for your save file folder. Label everything with the game name and the date so you can identify it instantly.
Method 2: Steam Backup Feature
Steam has a built-in backup tool that packages your entire game installation into compressed archive files.
The steps to use it are:
- Open Steam and go to your Library
- Right-click the game and select Manage
- Click Backup Game Files
- Choose your destination folder and click Next
- Steam will compress the game into a set of backup files you can restore from at any time
The limitation of this method is that it only backs up the game installation, not your save files. Always back up your save files separately using the manual method above.
Method 3: Steam Cloud Save
Steam Cloud automatically syncs your save files to Valve’s servers for supported games. To verify it is active:
- Open Steam and go to Settings
- Click Cloud
- Make sure Enable Steam Cloud synchronization is turned on
- Right-click your specific game, go to Properties, then Updates, and confirm Cloud Saves shows as enabled for that title
This is a useful safety net, but should not be your only backup. Steam Cloud can sync a corrupted save and overwrite your clean one if you are not careful.
Method 4: Using a Mod Manager With Built-In Backup
If you are using Vortex or Mod Organizer 2, both tools have features that protect your original files.
Vortex deploys mods using a hardlink system that keeps the original game files untouched in most cases. Before deploying any mods:
- Go to Settings in Vortex
- Click Mods
- Confirm your staging folder is set to a location outside the game directory
- Create a profile for your unmodded game state before adding anything
Mod Organizer 2 is even more robust because it uses a virtual file system that never touches the actual game installation. Your original files remain completely clean regardless of how many mods you install. This makes MO2 the safest option for heavily modded games like Skyrim, Fallout 4, and similar titles.
Method 5: Create a System Restore Point on Windows
Before any major modding session, create a Windows System Restore Point as an additional safety net.
- Type Create a restore point in the Windows search bar and open it
- Click Create at the bottom of the window
- Name it something like Before Modding GameName and click Create
- Windows will snapshot your system state, and you can roll back to it if something goes seriously wrong
This does not replace a file backup but adds a second layer of protection against system-level changes some mods make.
How to Back Up Game Saves on PC by Platform
Different game launchers store saves in different places. Here is exactly where to find them.
Steam Games
- Default: Documents\My Games\GameName or AppData\Local\GameName
- Steam Cloud saves sync automatically, but always keep a local copy as well
- Some older Steam games store saves inside the game folder itself under a Save or SaveData subfolder
Epic Games Store
- Default: C:\Users\YourName\AppData\Local\GameName\Saved\SaveGames
- Epic does have cloud saves for supported titles, but the feature is less consistent than Steam
- Always back up locally before modding any Epic title
GOG Galaxy
- Default: Documents\My Games\GameName or AppData\Roaming\GOG.com\GameName
- GOG Galaxy has a cloud save feature, but it must be manually enabled per game in the game’s settings within the client
Xbox Game Pass on PC
- Saves are stored in a hidden WindowsApps folder that requires administrator access
- The path is typically C:\Users\YourName\AppData\Local\Packages\Microsoft.GameName\SystemAppData
- Use the search bar in File Explorer with hidden items visible to locate these folders
- Some Game Pass titles store saves in OneDrive under Apps\GameName
How to Back Up Your Game on PlayStation
Sony’s consoles have significantly evolved their backup options. Here is what is available on PS4 and PS5.
PS5 Cloud Saves With PlayStation Plus
PlayStation Plus subscribers get automatic cloud backup for PS5 save data. To verify it is working:
- Go to Settings on your PS5
- Select Saved Data, Game, and App Settings
- Select Saved Data (PS5), then Auto-Upload
- Make sure Enable Auto-Upload is turned on for all games
Before modding or using any save editing tool, manually trigger an upload:
- Go to the same menu
- Select Upload Now to push your latest saves to the cloud immediately
PS4 Save Backup Options
PS4 offers two options for save backup:
Option 1: USB storage backup
- Insert a USB drive formatted as FAT32 or exFAT
- Go to Settings, Application Saved Data Management
- Select Saved Data in System Storage, then Copy to USB Storage Device
- Select the game saves you want to copy and confirm
Option 2: PlayStation Plus cloud saves
- Go to Settings, Application Saved Data Management
- Select Saved Data in System Storage, then Upload to Online Storage
- Select your saves and upload them manually before any modifications
Important Note on PS4 and PS5 Modding
Console modding that involves modifying game files directly typically requires a jailbroken console, which voids your warranty and can result in a permanent PSN ban. Saving editing tools that work through legitimate means is a different matter. Always research whether what you are doing is in accordance with Sony’s terms of service before proceeding.
How to Back Up Your Game on Xbox
Xbox handles saves differently from PlayStation, with a stronger emphasis on cloud synchronization.
Xbox Cloud Saves
Xbox automatically syncs all save data to the cloud for every game, with no subscription required. Before modding:
- Press the Xbox button on your controller
- Go to Profile and System, then Settings
- Select System, then Storage
- Confirm Cloud Gaming and Saves show as enabled
To manually sync before a modding session, close the game completely, wait 30 seconds for the sync to complete, then confirm the save appears in your cloud storage through the Xbox app on PC or through account.xbox.com in a browser.
Xbox Series X and S Local Backup
Xbox does not offer a direct USB save export for most titles, which means cloud saves are your primary protection. For this reason, always close your game and wait for cloud sync to complete before attempting any modifications.
How to Back Up Your Game on Nintendo Switch
The Switch has the fewest backup options of any major platform, making preparation even more important.
Nintendo Switch Online Cloud Backup
Nintendo Switch Online subscribers can back up save data for supported games. To use it:
- Go to System Settings on your Switch
- Select Data Management
- Select Save Data Cloud Backup
- Select the game and choose Back Up Save Data
Not every game supports cloud backup. Nintendo’s first-party titles like Animal Crossing, Pokémon, and Splatoon intentionally disable cloud saves to prevent duplication exploits. For these games, a Nintendo Switch Online subscription provides no save protection.
What to Do for Games Without Cloud Save Support
For games that do not support cloud saves, your only legitimate option without third-party hardware is to be extremely cautious about what modifications you attempt. Some games can be backed up using tools like Checkpoint, which is a homebrew application, but using homebrew software on a Switch carries the risk of a Nintendo account ban if detected.
How to Back Up Your Game on Mobile
Mobile game saves are often tied to accounts rather than local files, but there are still important steps to take before modding.
Android Game Backup
- Most Android games store saves in the Internal StorageAndroiddatacom.gamename folder.
- Enable Google Play Games cloud saves in the Google Play Games app settings before modding.
- For games without cloud saves, use a file manager app to manually copy the data folder to your SD card or Google Drive.
- If the game requires root access to modify, back up your entire device using Android’s built-in backup in Settings > System > Backup first.
iOS Game Backup
- iOS save data is synced through iCloud for supported games automatically
- Verify that iCloud backup is enabled in Settings > YourName > iCloud > iCloud Backup.
- Before modding, run a manual iCloud backup at the same location by tapping Back Up Now.
- iTunes or Finder backups on a connected Mac or PC capture everything, including app data, for a complete local copy
Creating a Modding Checklist You Can Use Every Time
Having a repeatable process is what separates people who lose progress once from people who never lose progress at all. Use this checklist before every modding session, regardless of how small the change seems.
Before you install any mod:
- Identify and locate your save file folder and copy it to a labeled backup location.
- Copy your game installation folder or use Steam’s backup feature to create an archive.
- Note the current version number of the game so you know exactly what state you are backing up.
- Take a screenshot of your current in-game settings screen so you can restore your configuration.
- Check your mod manager profile and export your current load order as a text file.
- Read the mod’s installation page completely, including the comments section for reported issues.
- Check whether the mod requires specific prerequisites, such as a script extender, and back them up too.
- Confirm the mod is compatible with your current game version before downloading.
After you install a mod and before playing:
- Launch the game and get to the main menu to confirm it loads without crashing
- Load an existing save rather than starting a new game to verify compatibility with your progress
- Play for at least 15 to 20 minutes across different areas or game systems before considering the installation stable
- If everything works, create a new in-game manual save at this point so you have a clean modded baseline to return to
How to Restore From a Backup When Something Goes Wrong
Knowing how to restore is just as important as knowing how to back up. Here is how to recover cleanly from a failed mod installation.
Restoring Game Files on PC
- Close the game and Steam or your launcher completely
- Delete or rename the current broken game folder
- Copy your backup game folder back to the original location
- Rename it to match the original folder name exactly
- Relaunch Steam or your launcher and verify the game files to confirm integrity
Restoring Save Files on PC
- Close the game completely
- Navigate to your save file location
- Delete or move the current save files to a separate folder in case you need them later
- Copy your backed-up save files to the save location
- Launch the game and confirm your progress loads correctly
Restoring Through Steam Verify Files
If you only need to restore modified game files and your save files are intact:
- Right-click the game in Steam
- Select Properties, then Local Files
- Click Verify Integrity of Game Files
- Steam will identify and replace any files that differ from the official version
This works for files that mods have overwritten, but it will not help if mods have added new files that Steam does not recognize as part of the official installation.
Final Conclusion
Backing up before modding is not a complicated process, but most people skip it until they lose something important. Once you have lost 60 hours of progress to a corrupted save, the five minutes a backup takes becomes the most obviously worthwhile investment in gaming.
The most important things to remember are:
- Always back up save files and game files separately because they are stored in different locations
- Never rely on a single backup method. Use both local copies and cloud saves wherever possible
- Use Mod Organizer 2 for PC games when available because it never touches your original files
- On console, manually trigger cloud uploads immediately before any modification attempt
- Follow the pre-install checklist every single time, even for mods that seem simple or widely trusted
- Know how to restore before you need to, so that when something does go wrong, you are already prepared
The mods that transform your favorite games are absolutely worth installing. Just make sure you can undo everything before you begin.
