Having been in the industry for 20+ years, we have seen and tested most on-premise backup solutions whether that be files only or image based.
In our experience, the most comprehensive solution with fastest recovery times is the image based method. Having looked at a multitude of vendors, we believe that the Veeam suite of products are the best on the marketplace and it is for that reason we chose to become a Veeam Silver ProPartner.
Veeam Backup & Replication is their flagship product that contains both backup and replication for fast recovery. Features such as file-level restore, data deduplication and compression save you time and money.
