Abstract
A virtual data storage system includes a device emulator and a storage system for storing data to a plurality of physical devices in accordance with storage management policies. The data received by the device emulator is converted into a data object. The data object and object specific metadata are stored to storage media in accordance with the storage management policies. The object specific metadata is stored separate from the data object. In addition, the object specific metadata is embedded into the data object. Upon detecting an error when attempting to access the data object, an extent of data loss is determined by examining the object specific metadata.
