Abstract:
Redundant data in a streaming disk image is identified using commands to indicate unused disk blocks, such as TRIM/UNMAP commands. A TRIM/UNMAP layer is added between an operating system and a disk driver to support the use of TRIM/UNMAP commands. Using the TRIM/UNMAP layer, blocks of a streamed disk image that are unallocated by the operating system are identified. The identified unallocated blocks are streamed to a server for analysis and storage.
