The callback for this method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

This method restores a key previously backed up using BackupKey to the currently-selected Vault. The key is restored in its entirety, with all of its versions intact. However, note that the restore will fail if the key's name is already in use. The name of the restored key is returned.

The protected key data to restore is taken from the the specified InputFile or the InputData property.

Note: There are certain restrictions on which vaults a key can be restored to. In particular, a key must be restored to a vault owned by the same Azure subscription that owned its original vault, and must be restored to a vault in the same geolocation as its original vault. Refer to the Azure Key Vault documentation for more information.
