Deduplication, Incremental Forever and the Olsen Twins


What do deduplication, incremental forever, and the Olsen twins have to do with each other? It's all about duplicate data. Mary Kate and Ashley Olsen are fraternal twins. Identical twins share the same 100% of their DNA. Fraternal twins share about 50% of their DNA - the same as any other sibling.

In this paper, we'll compare and contrast the advantages and disadvantages of the following deduplication techniques:

  • File-level deduplication
  • Block-level deduplication
  • Byte-level deduplication
  • Incremental forever

We will also discuss the advantages and disadvantages of both physical and virtual backup appliances versus dedicated deduplication devices.
