Backup Manager

How can I tell if the backup has worked I have backed up the program to a USB and when I click on the back up it comes up with error executing program I am running version 16.11.87

You can only “test” a backup by doing an Add Business & Import Backup.
Clicking on the backup file wont do anything.

The current version is now 17.1.6

Read the guide on restoring from back up first if you are going to do that.

Thanks for the info
