Does snapshot/suspend/resume keep processes/RAM alive - or do you need to re-start processes/reload stuff into RAM? How does that work under the hood (CRIU?) and how fast is it?

- bwm 27d agoNo CRIU. Snapshots are at the disk layer, not RAM. `machine0 suspend` takes a full disk snapshot and tears down the compute; you keep paying only for storage. `machine0 start` restores the disk and cold-boots the VM from it. So processes restart, they don't resume mid-execution. Practically: anything that survives a reboot survives a suspend.
