For example, if you install any patches to fix the software bugs or upgrade to a new version of the software, or even the entire operating system on your PC gets changed, you should test your backups as soon as possible.

When Application Data Changes Drastically

Aside from the application itself, if the data generated by the application changes greatly, you need to perform a test restore as well. More specifically, if you import any external data into an application, you have to verify the effectiveness of data backups, trying to restore the backups to validate the data recovery.

When New Application Is Installed

In addition, when you install a new application on your computer, such as a new virtual machine (VM) or a new server, you need test the restore, too. It’s because that installing a new VM or the server will significantly change the existing drive partitions. Hence, not only should you start a backup at once, but also you have to test the backup to see whether the backup are valid indeed.
