You can use a CVD snapshot to restore a specific file or a complete endpoint on an existing device.
Mirage automatically creates CVD snapshots at regular intervals, and preserves them based on a retention policy, making them available for restoration purposes as needed. See CVD Snapshot Generation and Retention.
You can use a CVD snapshot to restore a specific file or a complete endpoint on an existing device. Restoring a specific file is the same process as restoring a previous file version. To restore a specific file from a CVD snapshot, see Restore a Previous File Version.
When restoring a complete device from a CVD snapshot you can restore using the same operating system, for example, Windows 7 to Windows 7, or cross-operating systems, for example, Windows 7 to Windows XP or Windows Vista. However, you cannot revert a Windows XP CVD snapshot to a Windows 7 device or a Windows 8 CVD snapshot to a Windows 8.1 device, for example.
