Backup interval should outlive sessions

[NomarCub]

I want to make sure to save daily, or a couple of times a week, but I don't have Obsidian open for that long, so the automatic vault backup doesn't kick in in time. To consistently save across sessions, the plugin could save the last backup timestamp into a file, and then auto backup on startup, if the interval has passed, or set a timer until the next scheduled backup time.
This could also help with more consistent saving if saving on exit (#13) is not possible.

Great idea! So you have set the time to something like 12 hours?

I've set it to 10000 minutes and for a while forgot that it even existed.
