Analyst rankings of virtual server backup software put CommVault Simpana 9 and CA ARCserve r15 in place as the best all-round products.
The DCIG 2011 Virtual Server Backup Software Buyer's Guide is a collaboration between two analyst firms: Jerome Wendt's DCIG and SMB Research. They admit to paid assignments from some of the vendors whose products were reviewed, but say they were not paid to produce their report and it is an independent evaluation.
The analysts sent questionnaires to some 30 firms and received 24 replies. They classified the questions into various aspects of virtual server backup and recovery, weighted the replies according to user-related conversations, and scored the vendors' replies. The mean and the statistical deviation were calculated and vendors' products ranked on both the individual aspects and overall, with five rankings from Basic, through Good to Excellent, and then Recommended.
