Because disk-based backup with deduplication is not simply primary storage, vendors should have the proper tools to help you size the system correctly.
Keep in mind that with this sizing exercise, your goal is to avoid either (a) buying a costly system that has excessive capacity relative to your needs today, or (b) an undersize system that will require a forklift upgrade once data growth exceeds its capacity.
By carefully evaluating each of your scenarios and requirements upfront, and asking the right questions of the vendor, you can choose the right system that will positively impact backup performance for the long term.
