Systems and methods are disclosed for reconstructing a file hierarchy by scanning attributes of stored files. Stored files can have a file hierarchy that is maintained in a database stored on a storage device. The files can be stored as objects on the device using a flat file structure. The file database provides the file hierarchy. The systems and methods disclosed herein store information in file system extended attributes for individual storage files such that the database can be reconstructed by scanning the storage files, using values in the extended attributes to recreate the hierarchical database.

A network attached storage device may include at least one storage device, a network connection coupling the at least one storage device to a network and a processor coupled to the at least one storage device and to the network connection. The processor may be configured to monitor a plurality of operating parameters of the network attached storage; determine a state of a network attached storage based on at least two of the monitored plurality of operating parameters of the network attached storage; determine a current level of protection from among a predetermined plurality of levels of protection based on the determined state of the network attached storage, and provide an indication of the determined level of protection afforded by the network attached storage.

A media aggregator device includes a plurality of interfaces, at least one of which may be configured to couple to a local network and at least one processor coupled to the plurality of interfaces. The processor may be operable to access a first device coupled to the local network and catalog media content stored on the first device; access a second device and catalog media content stored on the second device; populate a media aggregator database with references to the media content cataloged in the first and second devices, and present contents of the populated media aggregator database to a client device to enable the client device to access any of the media content referred to in the media aggregator database, subject to appropriate access rights.
