Useless
What a useless MQ for a dying technology. "Purpose built dedupe appliances" were great 5 years ago but its just software and any backup app worth its value integrates it into the product with the biggest benefit at the source.
History:
1. VTL enabled easier backup to disk
2. Dedupe appliances allowed retaining more backups on disk with NFS/CIFS ability
Dedupe is a feature now. This MQ is simply an EMC marketing document to squeeze the last juice from the data domain fruit. Great acquisition at the time and EMC made a lot of money selling them but its time to move on.
Maybe their lead is so big because nobody is trying to catch up anymore.
