The plugin menu

These are under Plugins → Z-Wave Controller Backup.

Menu item What it does
Back Up Controller Now… Opens a short window showing the steps and the folder the backup will go to. Click Start, then switch Z-Wave off. The Taking a backup page has the details.
Restore Controller… Opens a window where you choose a backup, tick Replacement stick if it is going onto a different stick, and tick Confirm. Click Restore, then switch Z-Wave off. Read the Restoring a backup page first.
Verify Last Backup Starts straight away, with no window. Switch Z-Wave off, and the plugin reads the stick and compares it with the newest backup.
Show Plugin Info Writes the plugin’s version, details of your Mac and Indigo, the backup folder, the stick’s port, and what the newest backup says about the stick — its model, Home ID, software version, how many devices it holds, when it was taken, the file name, and whether the network has changed since — to the Event Log. It does not need Z-Wave switched off. It is the thing to include if you ask for help on the Indigo forum.

Indigo adds its own items to the same menu, such as Reload, which restarts the plugin.

Only one backup, verify or restore runs at a time. If you start another before the first has finished, which means before Z-Wave is back on, the plugin says one is already running. A restore that did not hold finishes straight away, so you can run it again at once.
