I have been searching around and finding little useful information about the snapshot and disk management features of bhyve. I want to setup a new system (coming over from Linux/KVM) using bhyve but before I go all in I am trying to understand what my backup strategy is going to be. This is going to be a home server / very light production server, but the data is still none the less important to me and I want to have a proper backup strategy in place.
How does one snapshot a bhyve disk that is ZVOL backed and get a consistent disk image? In the past I have done ZVOL snapshots on Linux but through QEMU you have the ability to command the machine to freeze and flush the disks before the snapshot so everything is consistent when the snapshot is taken. Does bhyve support any kind of mechanism like that?
