Users and Vendors alike have always had skepticism around capacity optimization and different points throughout history. The key, for end users is to be able to answer the questions:
- What are you doing to my data? - This is directly related to availability and data integrity. If you can't ensure the customer will always have access to their data and it will be 'their' data then there is an issue.
- Whatever you do to my data, you can't cause slowlyness. Which goes right to the performance question.
(These are consequently the two main characteristics being 99% of every storage purchase.)
Vendors always whine that they will sell less disk and these technologies will negatively impact margins. The reality is that the disk storage market is 100% elastic. Add reduplication to your backup environment, I promise you will buy more backup diks storage and keep more data on-line. Humans are funny like that.
Watch this brief video to see the storage challenges of today and how solving them will have the same 'feeling' it did even 10 years ago.
