What are VM Snapshots in vSphere?

Virtual machines provide a lot of benefits to organizations, but much like a normal computer running native software on bare-metal hardware, they can still experience issues and downtime. There are many tools that VMware offers to help reduce virtual machine downtime, though. One of those tools is snapshots.

Snapshots are files that preserve data and VM state for a virtual machine at a specific point in time. That data includes things like the current operational state of a VM, its power state, what information is in its memory, and the data for that virtual machine. Snapshots can be useful for things like failed updates for a virtual machine or VM host. If an update fails and causes issues, a VM can be rolled back to its last snapshot restoring it to an operational state.

It should be noted that snapshots should never be used as a backup mechanism. Snapshots are only ways to restore a VM to an operational state quickly and easily.
