Please would you tell me the best way to copy a backup to another disk as well as to the cloud. I see that it is easy to setup a backup to two destinations, but what about a third?
You can either run a second backup to the third storage location or copy files as needed. How you copy them is going to depend on where you are copying them. For local, you can use Robocopy. For local to cloud, you can use something like our Explorer products.
