Abstract
Systems and methods for reconstructing unified data in an electronic storage network are provided which may include the identification and use of metadata stored centrally within the system. The metadata may be generated by a group of storage operation cells during storage operations within the network. The unified metadata is used to reconstruct data throughout the storage operation cells that may be missing, deleted or corrupt.
Claims20
An apparatus that reconstructs missing metadata in an electronic storage network comprising:
- primary data stored on at least a first storage device;
- at least a secondary copy of the primary data;
- a first set of metadata associated with at least a portion of the secondary copy;
- a database of metadata that stores a copy of the first set of metadata;
- and
- at least one storage operation controller comprising computer software executing on one or more computer processors, the at least one storage operation controller configured to:
- electronically determine that a missing portion of the first set of metadata is not stored in the secondary copy;
- determine whether the copy of the first set of metadata comprises the missing portion of the first set of metadata;
- and
- automatically reconstruct the missing portion of the first set of metadata using the copy of the first set of metadata stored in the database of metadata.

A method for reconstructing missing metadata in an electronic storage network, comprising:
- copying primary data stored on at least a first storage device to at least a second storage device to create at least a secondary copy of the primary data on the second storage device;
- creating a first set of metadata associated with at least a portion of the secondary copy;
- storing a copy of the first set of metadata in database of metadata;
- and
- determining that a missing portion of the first set of metadata is not stored in the secondary copy;
- and
- determining that the copy of the first set of metadata comprises the missing portion of the first set of metadata;
- reconstructing the missing portion of the first set of metadata using the copy of the first set of metadata stored in the database of metadata.
