Hi,
If you want to use snapshot, you should know how the snapshots work. For more information, you can refer to:

Virtual Machine Snapshotting under Hyper-V

General speaking, it is not recommend that you use snapshots in production environment. You can refer to the following blog.
Should virtual machine snapshots be used in production?

By the way, you can export the VM with snapshot, however, if you move the exported VM to a different version of Hyper-V computer, you may can’t
revert the snapshots.
In addition, please don’t use snapshots with Live Migration. For more information, you can refer to:
Snapshots and running virtual machines
You should avoid taking a snapshot of a running virtual machine. If you revert back to a snapshot of a running virtual machine, the memory state is restored
in addition to the disk. Before reverting a clustered virtual machine back to a snapshot, you should first shut down the virtual machine from Failover Cluster Manager, take a snapshot of the virtual machine, and restart the virtual machine.
