Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for storing data are disclosed. In some implementations, visual representations of files are generated for presentation in a backup user interface. The visual representations are generated from sparse file system metadata stored on the computing device, thus allowing faster navigating of the backup user interface. During a restore operation, the metadata can be used to retrieve the items from their physical storage locations. In some implementations, when the storage capacity of a backup storage device exceeds a threshold, the data for the N oldest backups are replaced with sparse file system metadata, which can be used to generate visual representations for presentation in the backup user interface.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for file system management. In one aspect, a method includes receiving a request at a kernel to perform a file operation on a particular file; identifying a flag bit associated with the file; invoking user space file handler to perform particular action when the flag bit is set; determining whether notification that action has been performed by file handler is received; and allowing the file operation on the file when notification is received.

Abstract: Methods, systems, and apparatus, including computer program products, for searching for and presenting backups. A first search result including a first version of an item is presented. The first version is associated with a first date range having a first start date and a first end date. User input requesting that an archive including one or more versions of the item be searched is received. A second search result including a second version of the item is presented. The second version is different from the first version. The second version is associated with a second date range having a second start date and a second end date. The second date range does not overlap with the first date range.
