How to Back Up PC Game Saves Before a Windows Reinstall or SSD Upgrade
Steam Cloud helps, but it is not a complete backup strategy. Here is how to protect saves before reinstalling Windows or moving drives.
Before reinstalling Windows, replacing an SSD or moving to a new PC, game saves deserve their own backup plan. Steam Cloud is useful, but Valve explicitly warns that not every game stores every save in the cloud.
First: check whether the game uses Steam Cloud

Valve’s Steam Cloud FAQ says the store page shows a cloud logo when a game supports the feature. Developers choose which files are synced, so cloud support does not guarantee every configuration or save is included.
Let Steam finish syncing before you wipe anything
Open Steam while online, exit the game normally and confirm there is no sync error. Valve warns that launching through an unresolved cloud conflict can lead to older data replacing newer progress.
Copy local saves too
Common locations include Documents, DocumentsMy Games, AppData and the game’s own folder. Valve notes that third-party games can store saves wherever the developer chooses. Search the developer’s support page or community documentation for the exact path.
Steam’s game backup is not automatically a save backup
Valve’s Steam backup documentation warns that backups of Valve-created games do not automatically include save games, custom maps and configuration files. Treat installed game files and personal save data as separate things.
Use a second location
Copy important save folders to an external drive or a cloud-synced folder. Microsoft’s OneDrive folder backup can protect Documents and other standard folders, but it will not automatically catch a save stored somewhere else.
Test before deleting the old drive
After Windows is installed, restore one important game first and verify the save loads. Do not wipe the old SSD until you know the backup contains what you expected.
A two-minute manual copy is cheap insurance against losing a hundred-hour save.
