Imaging mounted disk volumes under duress

The dattobd [1] block device driver fills this gap. It basically implements point in time like behavior on Linux, with hooks similar to the ones that VSS provides. It is used in the Datto Linux backup agent in combination with the backup appliance [2], but it can be used stand alone as well (see readme).

This is just the coolest thing in the world, thank you so much for open sourcing it.

Have you asked upstream what they think of it, at all?

Hey, I'm one of the folks that work on maintaining dattobd. We haven't had a chance to talk to the upstream Linux kernel storage folks about a way to upstream it, but we're interested in exploring it, of course!

Once the world gets more back to normal, you could submit a talk topic to LSF/MM. Or just email the appropriate mailing list.
