Abstract:
Method, apparatus, and computer readable medium for managing an image of a storage volume are described. File extents for each of a plurality of files as defined in an original block layout of the image are obtained. A re-ordered block layout is generated by re-ordering, for each file of the plurality of files, blocks as defined by the original block layout based on the file extents of the respective file such that the blocks are contiguous. Layout metadata indicative of a mapping between the original block layout and the re-ordered block layout is generated. An archive image having the re-ordered block layout and the layout metadata is stored to a sequential storage device.
