Back up and restore Steam game files while protecting saves separately
A game-file backup and protection of saves or custom content are separate tasks. Keep the original installation and important data copies until you have verified restoration.

What you need
- Update the game and check available backup storage
- Check the actual save directory in developer documentation
Identify what the backup covers
The feature is intended for games downloaded, installed and patched entirely through Steam. Titles using third-party installers or downloaders may not be compatible. Check the publisher procedure when an external launcher is involved.
The purpose here is to prepare reusable installation data. A game-file copy does not restore an entire PC. List installation files, progress and additions separately so you know which copies you need.
Make separate copies of saves and additions
For Valve games, Valve states that game backups exclude saves, custom maps and configuration files. Save locations vary for third-party games; consult the developer. Keep a separate copy of important progress even when Cloud is supported.
Name the copied folder with the game and date, and record its original location in a text note. This prevents confusion during restoration. Record installed mods and their setup instructions rather than assuming the backup contains them.
Create a game-file backup in Steam
Right-click the game in Library, open Properties > Installed Files > Backup game files, choose the destination and create the backup. Confirm the title and destination in the current interface before starting.
For protection against a drive failure, use a different storage device from the one you are concerned about. Do not disconnect it during copying. After completion, open the destination and check that backup files are present.
- Open Installed Files for the selected game
- Choose the backup destination and create it
- Inspect the output folder after completion
Restore using the correct account
Sign in to the account that owns the game, then use Steam > Restore Game Backup and select the backup location. Follow the prompts to choose installation storage. Backup files do not replace a game license.
If storage is insufficient, consider another destination instead of deleting your only backup. Allow for further downloads when the game has changed since backup creation; do not assume the process will be entirely offline.
- Choose Restore Game Backup from the Steam menu
- Select the backup and installation destination
Verify restoration in three stages
First check that Steam recognizes the installation, then that the game launches, and finally that the intended save loads. Only after all three checks should you treat the copy as usable for recovery.
Valve recommends testing created backups. File existence alone does not establish successful restoration. When checking on another device, preserve its important saves before doing anything that might replace them.
Handle failures and decide what to retain
If restoration fails, check completion, interruptions, destination readability and compatibility. Valve notes that special characters in the Steam installation path can cause restoration issues. Avoid changing unrelated settings together.
Retain the separate save copy for a while after checking. If pruning old backups, record when the newer copy was successfully restored before deleting the older one. Consider future use as well as storage pressure.
Build a protection checklist before replacing a PC
Before replacing a PC, list game names, backup folders, save locations, account and custom files on one sheet. Include creation date and completion checks so multiple copies are identifiable during recovery.
For a game with custom maps, record the installation backup, map copy and save copy separately. Note Cloud support as additional information, not automatic grounds to omit manual protection. Keep unchecked items visible.
Before restoring on the new PC, open the backup storage and check that all required copies are readable. Keep the old PC until the same progress and custom content work on the new one. Erasing old data is a separate decision after verification.
What a restoration test should establish
A restoration test goes beyond a successful backup-creation screen. Actually load the copy through Restore and launch the game. Where practical, test on another destination with sufficient space and note the date and game state.
Before restoring saves, also copy the destination current state to avoid overwriting newer progress. Follow developer folder instructions and check account or profile. Matching filenames do not establish compatibility across editions or operating systems.
If a backup cannot be read, do not repeatedly modify your only copy. Preserve it and use a working copy while separating backup errors, destination problems and unsupported titles. Do not present an unverified backup as a guarantee against redownloading.

|---|---|
| Backup creation completed only | Restoration testing is still needed |
| Game launches, progress absent | Check separate save restoration |
| Custom maps missing | Check custom-content copies outside the backup |
Limitations and requirements
- Do not assume saves or all mods are included
- Do not delete your only copy before restoration is verified
Frequently asked questions
Does Cloud eliminate the need for a save copy?
Keep a separate copy for important progress. Synchronization is not versioned backup, and each game decides which files it includes.
What if I want to preserve every installed game?
Valve points to its Steam installation-moving procedure for this use case. Plan client, library and save protection first, because this is broader than backing up one game.
Can backup files be stored on an external SSD?
Storing a backup differs from running the client there. Check capacity and readability, keep it connected during creation and restoration, and perform an actual restoration test.
Should an old backup be recreated?
Frequently updated games may need extra downloads after restoring an old copy. Create a newer copy when practical, verify it and then prune old copies. Update save protection separately.
