Unfortunately, many users complained they couldnt really tell if File History is working or not.
Right-choose theFile History folderand selectProperties.
Wait two minutes, and return to File Explorer to see if the file size has changed.
Alternatively, go toControl Panel System and Security File Historyand check the backup status.
If you want to check your backup files, kick off the File History log.
Navigate to %SystemRoot%\System32\Winevt\Logs\Microsoft-Windows-FileHistory-Core%4WHC.evtx.
Check when was the backup file was last modified.
Alternatively, go to your File History folder and check the dates.
Enter D:\FileHistory in the search bar and check the results.
Dont forget to replace D:\ with the actual drive letter for your current configuration.
Of course, the ultimate test is to actually restore your data.
File History is limited in its capabilities.
It has a rather counter-intuitive user interface.
Keep in mind that File History was initially designed to back up individual files, not multiple files simultaneously.
Third-party backup tools can help you back up all your files at once.
