@Lusbueb this looks interesting.

Do you stop mm before the back up?

My mirror configuration has taken some time to get right and i’m curious to know people’s back up and restore methods in case of system failure.

I’ve seen some backup the whole sd, some just the config file, i see advantages and disadvantages to both of these. If the sd is backed up, maybe the module code is out of date, if just the config file, there is the potential to lose Raspbian specific settings.

Curious to know how people approach this.
