Backing up
It's a good idea to back up after adding a recording.
The laptop is set up to automatically back up whenever it has an internet connection. Unfortunately there is no internet connection at church, so the best way is to use your phone as a mobile hotspot and temporarily connect the laptop to your phone.
The backup software is called ownCloud and should notice that you're online in a minute, and back up the changes to the OrganAssist files. You should see one or more popup messages like this one. When they've stopped, it's probably finished the backup and you can disconnect your phone.
