WikitipDedupe starts hereIf you're considering data deduplication/disk-based backup, the fundamental starting point should be RPO (recovery point objective) and RTO (recovery time objective). If RPO's are very tight and you want to send dedupe data over the network - then you'll want to consider server-based solutions like Avamar, which are more expensive. If on the other hand your applications have more relaxed RPO requirements then you'll have more time to de-dupe and send de-dupe data over the net. This approach will save a bundle. Another consideration is size and scale. If you're small (less than 10 tb) then there are a variety of vendor/product choices. If greater than 10TB, the choices narrow significantly. The other consideration is doing in-line or post process dedupe. Data domain and Diligent, etc do inline, Falconstor and others do post process. From a business perspective, post process allows you to do the backup faster, then you perform the dedupe. But you've added another process in the stream meaning the whole procedure takes longer and is more complex. Meaning RTO will be extended. In line slows down the backup process but overall it's faster and easier to manage. So your RPO goes up but your RTO goes down. You might also want to consider outsourcing disk-based backup as a remote service (e.g. IBM and others) which brings other considerations. |
Featured Case StudyFinancial giant goes greenThe corporate IT group of a very large, worldwide financial organization with 100,000 employees, has initiated an ongoing “greening” process. This is focused largely on reducing energy use both to decrease the corporation's carbon footprint while creating a net savings in operational costs over the lifetime of new, more energy-efficient equipment, including new storage systems. |

Featured How-To Note |
Planning a Green Storage InitiativeFluctuating energy prices have heightened electricity and energy consumption as a major issue within the technology community. IT is a significant consumer of energy and IT energy costs have been rising disproportionately because of continued investment in denser IT equipment. Estimates from the EPA and others indicate that IT will account for 3% of energy consumption by 2012. |
