Branko Cirovic - PeerSpot reviewer

Storage Engineer at Comtrade Group
Provides seamless backup integration and long-term reliability for enterprise data protection
The price is quite high; this product is not considered cheap. Additionally, if you use higher availability boxes, they also come at a premium price. However, they provide business continuity, which is the main reason why companies invest in this solution. Tape is slow; when restoring several virtual machines or databases amounting to several terabytes, Dell PowerProtect Data Domain represents the fastest and most reliable solution, ensuring great integration with backup software. If a customer has limited budget constraints, they may opt for cheaper external storage comprised of just a bunch of disks and utilize it for backup, as backup is not a business-critical service. However, I see great value in Dell PowerProtect Data Domain because it is fully automated, features great integration with backup software, and provides good value for money. I would rate software support as a ten, while I would give hardware support a seven. I never give any product a perfect score; I think Dell PowerProtect Data Domain deserves a nine. The only minor problems are the certificate issue and the price. These certificate issues are quite rare and mainly arise when we forget to restart and upgrade the box for several years.
