You can restore device files to a previous CVD snapshot, or restore a device from a CVD following hard drive replacement, file corruption, or format, or when the device is replaced.
Mirage provides disaster recovery in two key ways:
Restore files or the entire desktop to a previous CVD snapshot on an existing device. Files and directories are included in CVD snapshots in accordance with the upload policies currently in effect. See Working with Upload Policies.
Restore the hard drive on an existing or a replacement device:
Restore a CVD to the same device after a hard-drive replacement, file corruption, or format.
Restore the CVD to a replacement device.
When the CVD contains Encrypted File System (EFS) files, the files are recovered in their original encrypted form.
For better deduplication in the revert-to snapshot, the end user must be logged in during the restore Prefetch operation if the CVD contains EFS files.
