Abstract
Various methods and systems for performing extent-level backups that support single file restores are disclosed. For example, one a method involves accessing a list, which identifies several extents of a first storage device in a non-contiguous order. The non-contiguous order is non-contiguous with respect to an order in which the extents are arranged on the first storage device. The method then involves reading information from the extents of the first storage device, in the non-contiguous order identified by the list, and the writing the information to backup media. The information is written to the backup media in the non-contiguous order identified by the list. As a result, a first portion of the information, which is included in a first data object, may be less fragmented on the backup media than on the first storage device.
