Check multiple file's modified date, report if any are older than x minutes (or if any file is missing). Also check if the drive that the files are on has less than X GB of free space, or if it is marked as not Healthy by Windows.

Here is an example Scheduled Task to generate a text file and have it be updated every 5 minutes. Save it as an .xml file and import it into Scheduled Tasks. Change the user account to a user on your system (or set the user to 'Local System'), and the file path to what you need. This is a way to generate a file with a new timestamp in a folder which gets backed up, and then use the powershell scripts above to check the backups to make sure files are being backed up.

Task Scheduler XML File. Copy the following text and save it as a .xml file, then import it into Task Scheduler. You then need to change the username that it runs as and enter the password when you save it. This assumes that curl.exe is available on the computer.

If you call a Powershell script, you can call it using this format. This works in batch files and in Task Scheduler:
