You can use a backup tool to save copies on a schedule. Choose one that supports your device and backup destination, then check that it includes the files you need.
Choose a method for your device
On a Mac, Time Machine can make automatic backups to a supported backup disk. Follow Apple's guide for your version of macOS.
On Windows, File History can back up files in your libraries to an external drive or network location. Use Microsoft's instructions to include other folders you need.
These tools have their own destination requirements. A folder visible in Store does not by itself show that it is a supported destination for either tool.
Before setting up a backup disk, check whether the tool will erase it. Keep separate copies of anything on that disk that you need to retain.
If you keep an additional copy in Store
Follow the upload and retrieval exercise in the 3-2-1 backup guide. Uploading a file once does not schedule future copies of its source folder. Keep a reminder to update that copy unless you have confirmed and tested a supported automatic method.
Check one scheduled backup
Choose a small folder and record its original location and backup destination.
Check that the tool includes that folder and can reach the destination.
Set a supported schedule based on how much recent work you could afford to lose. Read the tool's rules for keeping older versions.
Let one backup finish and check its recorded result or errors.
Retrieve a file into a separate location, open it and compare the version and contents with the original.
A disconnected backup drive may delay the next update. Follow the tool's guidance for reconnecting it, and check that a backup completed afterward. If the job fails, keep your originals, check the tool's error guidance and repeat the backup and retrieval check after fixing the cause.
Record the result
Write down the tool, folder, destination, schedule, last completed backup and retrieval result. Use the backup test guide for the full check. An automatic schedule still needs review when files, devices or settings change.
