Reduce the Amount of Redundant Data to Maximize Backup Investment. Read more.

In this paper, we'll compare and contrast the advantages and disadvantages of each of these techniques and explain why incremental forever when combined with byte-level deduplication is the superior methodology for reducing redundant data in the most efficient manner possible.

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.

File-level deduplication, block-level duplication, byte-level deduplication, and incremental forever are all techniques that eliminate duplicate data. Theoretically, the data reduction achieved is identical for each when 100% of data is duplicated. Practically, there are significant differences in the time and computational resources required between each of these techniques. It's when only some data is duplicated, as in the case with the DNA of fraternal twins, that the data reduction varies. The time and computational resources required with each of these techniques also varies in this case.

In this paper we will discuss:
• Advantages and disadvantages of each technique
• Benefits of combining incremental forever and deduplication
• Pro's and con's of physical and virtual backup appliances versus dedicated deduplication devices
