Patent number: 8626741Abstract: A process for organizing data objects backed up from a content-addressed storage systems is disclosed. Content-addressed storage systems back up data objects in a flat directory, labeling them with non-intuitive user-unfriendly content addresses. Such directories can be large and difficult to browse, making selective recovery of desired data objects inefficient and laborious. When the content-addressed storage system is further archived to a secondary storage device, such as tape, navigation of archived data objects is especially tedious and difficult. An embodiment of the present invention enables easy navigation of a data object directory created by building a pseudo-file structure as content addressed data objects are archived to a secondary backup device. The file structure of the data object director is based upon timestamp metadata extracted from each data object, resulting in a navigable directory tree that is more intuitive and user-friendly.Type: GrantFiled: June 15, 2007Date of Patent: January 7, 2014Assignee: EMC CorporationInventors: Bala Vijayakumar, Suman Tokuri, Ramachandaran Srinivasan
