HP StoreOnce - the basics of HP deduplication software pt 2

Last Friday, I had a post titled HP StoreOnce - the basics of HP deduplication software.  Today I bring you part 2  of that discussion.   This one is really interesting and Jeff DiCorpo digs into some of the HP Labs technology inside HP StoreOnce deduplication software.  There are three areas that Jeff discusses:

  1. Sparse indexing: this relates to how a dedup system checks new data against old data to see if there's a match. 
  2. Variable chunking: this is the highlight of the video.  Jeff does a great job using a sentence to show how variable and fixed chunking results would differ. 
  3. Flexible architecture: HP StoreOnce doesn't have dependencies on a file system, storage or operating environment.  This will help us to make StoreOnce as a single deduplication method beyond just the D2D Backup System into virtual machine or HP Data Protector software. 

Hopefully that overview whets your appetite to learn more so here's the video:

You can learn more about HP StoreOnce on our hp.com page.  Finally, as a basis of comparison, here's a new paper that compares StoreOnce deduplication to NetApp deduplication.  While this obviously represents our thinking, I think the comparison is fair.
