I am in the Apple ecosystem, but this strategy is universal. Every month I am reminded by my calendar to make a backup. That means:

A Photos export to flat file format for photo and video An iCal backup (easily imported elsewhere) A vCard backup of contacts A bookmark backup A to do list export by pasting to a .md Same for notes

I like the easy way an ecosystem lets all my things play nice together, but I don’t want to be beholden to it. This is an acceptable workaround to me.
