Fixing Steam Deck Cloud Sync Errors 2023: The Ultimate Guide

The Steam Deck is Valve’s powerful new handheld gaming PC. With its ability to play AAA games on the go, it has become hugely popular. However, some users have experienced issues with Steam Cloud sync on the Steam Deck. This can lead to game saves not syncing properly across devices.

In this comprehensive guide, we will cover everything you need to know to fix Steam Deck cloud sync errors. We will explain what Steam Cloud is, why sync errors occur, and provide step-by-step solutions to get your Steam Deck syncing properly again.

What is Steam Cloud?

Steam Cloud is Valve’s cloud storage system. It allows Steam users to store game saves, settings, screenshots, and other data online. This data then syncs across all devices logged into the same Steam account.

The key benefit of Steam Cloud is convenience. You can pick up where you left off in a game, even when switching between a gaming PC and the Steam Deck. Your profiles, keybindings, achievements, etc. carry over too.

Steam Cloud is enabled by default for most games. Developers have to actively implement support for it in their titles. When working correctly, Steam Cloud runs seamlessly in the background.

Why Does Steam Deck Cloud Sync Fail?

There are a few common reasons why Steam Cloud sync can fail on the Steam Deck:

  • Network issues– Sync relies on an internet connection. Connectivity problems will disrupt the process.
  • Steam server problems– Issues on Valve’s end can prevent syncs from going through.
  • File conflicts– If a cloud and local save conflict, syncing may fail until the conflict is resolved.
  • Steam Cloud save size limits– There are limits to how much data can be synced for each game. Excessive saves may fail to sync properly.
  • Game not supporting Steam Cloud– The game must have Steam Cloud enabled by the developer for syncing to work.
  • Corrupted local data– Damaged local save files or configs may fail to sync up to the cloud.
  • changing the Steam Deck’s system clock– This can confuse Steam Cloud over file versions.

Understanding the source of the issue is key to finding the right solution. Next, we will go through how to fix some of the most common Steam Deck cloud sync errors.

Fixing Steam Deck Cloud Sync Error Codes

Steam may return specific error codes that give clues as to why cloud sync has failed. Here are some of the key Steam Cloud error codes and how to fix them:

Error Code -18 (Sync conflict detected)

This typically occurs when the cloud and local save game differ. Steam can’t determine which one is correct, so refuses to sync.


  • Delete the local saved data and re-sync from the cloud. This will overwrite your local progress but restore syncing.
  • Browse to the Steam cloud folder on your PC (C:\Program Files (x86)\Steam\userdata\[userid]\760\remote). Manually delete the conflicted cloud save. Then relaunch sync on Steam Deck.

Error Code -19 (Corrupt sync data)

Some parts of the saved data or configs have become damaged. Steam refuses to sync it in this state.


  • Delete local save data and configs via Steam Deck settings to re-download fresh from the cloud.
  • Verify the integrity of game files on Steam Deck. This checks for corruption and redownloads if needed.
  • Back up saves externally then uninstall/reinstall the game. Wipe all old local data.

Error Code -20 (File syncing temporarily disabled)

This points to an issue on Valve’s servers. Steam has temporarily paused syncing for maintenance or high loads.


  • Wait it out – syncing will automatically resume when server issues are fixed on Valve’s end.
  • Restart Steam on all devices to force a recheck of server status

Error Code -105 (Steam Cloud storage full)

You have exceeded the maximum cloud storage allocated per game. New saves are failing to upload.


  • Launch the game on a PC and manually delete old/unused saves from the Steam cloud folder.
  • Use a utility like Steam Cloud File Manager to clean up files.
  • Uninstall large or unused workshop mods to free up capacity.
  • Contact Steam Support and request your cloud storage allocation be increased.

General Fixes for Steam Deck Cloud Sync Issues

If you do not receive a specific error code, try these general fixes to get Steam Cloud sync functioning again:

Ensure the Game Supports Steam Cloud

Check in the game properties within your Steam library if ‘Steam Cloud’ is listed as an enabled feature. If not, it is not the Steam Deck’s fault – the game simply does not work with cloud sync.

For single-player games, you can manually transfer saves via USB drive or cloud storage instead.

Check Internet Connectivity

Make sure your Steam Deck has a stable internet connection. Steam Cloud requires an active connection to send and receive data.

Restart your router and Steam Deck. Switch between wifi and mobile hotspot to test if one network is problematic.

Validate Local Game Files

Via the Steam Deck menus, go to the game properties and select ‘Verify Integrity of Game Files’. This will check all local data for errors and re-download any corrupt bits.

Fixing damaged files may allow cloud sync to work again after verification is completed.

Force Steam to Re-Sync Data

Restart Steam on your Deck. When opened again, it will recheck all cloud data and attempt to sync any unsynced changes.

You can also delete the app_data folder for the specific game under ~/.var/app/com.valvesoftware.Steam/data/Steam/steamapps/ then relaunch Steam for a fresh sync.

Ensure Steam Cloud is Enabled

Double-check in Steam’s settings that Cloud Sync is enabled for the game. Right-click the game > Properties > Updates tab. Make sure ‘Enable Steam Cloud synchronization for this game’ is ticked.

Check System Clock

If your Steam Deck’s system clock gets changed manually, this can confuse Steam Cloud over which saves are newer.

Go back to the automatic time setting if altered. Ideally, sync your Linux system clock to the same time server as your router.

Delete Old Game Saves

Excessive local saves or configs can overwhelm Steam Cloud’s sync process. Open the game’s local data folder (in ~/.var/app/com.valvesoftware.Steam/data/Steam/steamapps/compatdata/) and delete unneeded files.

Then restart Steam to refresh cloud sync. This may help if outdated local data is clashing with the cloud.

Contact Steam Support

For persistent sync errors, contact Steam Support. They can investigate issues on Valve’s servers that may be blocking your Steam Deck from syncing properly.

Advanced Steam Deck Cloud Sync Fixes

If the above doesn’t work, some more advanced troubleshooting is required. These steps involve navigating your Steam Deck’s filesystem and editing configs, so proceed carefully:

Wipe All Local Steam Cloud Data

Warning: This will delete all local Steam Cloud data on your Deck. Only attempt if you have backups or don’t mind losing local progress.

In a terminal, run:

Copy code

rm -rf ~/.var/app/com.valvesoftware.Steam/data/Steam/

This will wipe all cached Steam data including Steam Cloud files. When you next launch Steam it will re-sync everything from scratch.

Delete Problematic Game’s Cloudconfig File

You can force Steam to fully re-sync a specific game’s cloud data:

  1. In your Steam library, right-click the game > Manage > Browse local files
  2. Open steamapps/compatdata/[gameID]/pfx/drive_c/users/steamuser/AppData/Roaming/Steam/CODEX
  3. Delete the cloudconfigfile (may be named cloudconfig_eu, cloudconfig_asia etc)
  4. Restart Steam and launch the game. Fresh cloud sync should now occur.

This makes Steam forget previous sync details so has to start from scratch again.

Enable Steam File Verification

Steam trusts remote cloud data over local without checking. You can make it verify integrity before syncing:

  1. Shut down Steam
  2. Open the config file at ~/.var/app/com.valvesoftware.Steam/config/steam/config.vdf
  3. Find Cloudsection and add “AllowCachedCredentials” : 0
  4. Restart Steam – now it will verify cloud data before overwriting local files.

This slows down sync but ensures remote changes are valid before applying locally.

Hopefully, the steps above have helped resolve your Steam Deck cloud sync issues! With the right fixes, you can enjoy seamless cloud sync for all your Steam games on the go.
