Richard can't do a backup -- it just stops. Leo suggests running "ChkDisk" to see that everything is OK with the data. But Leo also says that Microsoft's backup program isn't all that great because it dumps all of the data into one giant furball of 1s and 0s. That means it has a single point of failure. And there's no way to know if it has it all of the data or not.
Leo prefers just backing up all the critical data (like images, video, and critical documents) and copy them straight over to a hard drive. He can use Microsoft's SyncToy. it's great to run as a synced backup.
