Issues cannot be avoided in virtual environment so you need Hyper-V disaster recovery tool. Thanks to snapshot, virtual machine can be easily recovered. How snapshot works in virtual environment and how to restore VM from snapshot?
What is VM snapshot?
VM snapshot is of much help to IT administrator, which needs to be manually taken. After the snapshot is taken, the status of VM (power on or off, memory, etc.) will be saved. If a VM crashes, IT administrator can easily recover the VM with the snapshot and magically revert the VM to the previous state when the snapshot is taken.
You can easily create VMware snapshot in vCenter. Just right-click the VM, select Snapshots, and then select Take Snapshot.
In Hyper-V environment, snapshot is also called checkpoint and works like differencing disk to save VM state. To create a snapshot in Hyper-V environment, just right-click the VM in Hyper-V Manager and then select Checkpoint.
VM snapshot is recommended to be used in test environment or for short-term disaster recovery. Compared with VM backup, it is not powerful enough to protect the whole IT environment in the long term. Vinchin Backup & Recovery can provide integrated disaster recovery solution for virtual environment.
