And a few parting thoughts when considering a new backup solution, in general:

We strongly encourage customers to explore reference architecture design alternatives before choosing a specific product for deduplication. In most cases, backup architecture redesign is the best way to maximize re-use of existing backup assets and take full advantage of next generation backup technologies, such as VTL and deduplication. In addition, performing a vendor-neutral performance and sizing analysis for core and remote sites is the only way to properly plan for deduplication both from a technical and budgetary perspective.
