I previously posted a survey highlighting the different methods of protecting VMware environments. The responses suggested that host-based backup is the predominant approach. The least popular choice was “Dedicated VMware backup application (Veeam, Vizioncore, etc..)”. These solutions exclusively protect virtual environments and they remind me of continuous data protection (CDP) technologies from the past.
Three years ago, CDP was hot. It was a major industry buzzword and several companies were founded focusing exclusively on technologies that claimed to enable CDP functionality. CDP enabled instantaneous backup, recovery and roll-back of critical data and some predicted that it would replace traditional data protection. CDP upstarts made voluminous statements about the technology and the future, but they had miniscule installed bases particularly when compared to the traditional backup application vendors. The challenge for the CDP providers was convincing end users to replace or augment existing backup infrastructures. This was a challenge since end users had substantial investments in backup software, hardware and knowledge. Although CDP provided customer value, it was only practical as a complementary solution to traditional backup and CDP functionality should have been embedded in existing backup applications. As a result, most dedicated CDP companies were either bought or went away, and we now see backup ISVs including CDP functionality.
