Abstract
An invention is disclosed for maintaining out-of-band metadata for data. In embodiments of the invention, an upper layer of a storage stack determines that the metadata of a lower layer of that storage stack may have become out of sync. In response, the upper layer may issue a series of commands to the lower layer based on the metadata. In other embodiments of the invention, an offload-copy operation on data may also transfer out-of-band metadata so that it is applied to the data at the destination.
