If you use zfs for docker, dbs and vms you don’t have to shut down anything. Just snapshot and send/recv to sync snapshots to another ZFS drive.

You can even mount and copy the latest snapshot to the cloud with rsync/rclone; probably also borg/restic/kopia. Each applications state will be internally consistent if the snapshot is performed for all data at the same time. If you’re paranoid you can stop everything for a few mins to perform the snapshot, but it’s not really necessary.

Late stage capitalism will end like the opening scene of the dark knight; the joker killing every one of his criminal accomplices, one by one, as soon as they have fulfilled their role (their value has been extracted).

It’s an apt analogy because all of these capitalists are mentally ill &/or criminals.
