Why do these groups diverge from the central backup offering? First, the backup team does not meet their needs. Second, unlike a decade ago, each group can create its own solution. The root of the problem is that the three core backup technical trends drive the divergence.

• Performance. Backup and recovery performance drives customer satisfaction. With more VMs, consolidated applications, billion-file NAS servers, and remote offices around the globe, backup teams struggle to maintain service levels. Since businesses are pushing IT to improve services, backup remains a critical bottleneck. In response, hypervisors, applications and storage systems have built tools to help optimize backup (e.g., VMware’s Changed Block Tracking, which can enable 10x better backup and recovery performance). Of course, if the company’s legacy backup application does not support the optimizations, the other teams will find point products that do. 
• Visibility. VM, application, and storage administrators understand that data drives the business. They worry about not knowing the status of their backups. They complain that much of the time-critical restore workflow is out of their control. They want more visibility into their data protection and more control over restores. If the company’s backup team does not enable broader visibility, the other teams will deploy point products that they control. 
• Disk Backup. When tape was the only viable backup media, centralization was required. Most application administrators didn’t want to purchase, manage, or attach tape devices to their servers. Disk, on the other hand, enables groups to create their own backup solution.
