And the 42 percent penetration today isexpected to grow to 63 percent in the next two years.The No. 1 reason that IT organizations virtualize is toconsolidate physical servers (71 percent), followed byimproved disaster recovery (54 percent) and improveddata protection (51 percent). Yet one of the primarygating factors to end-user adoption of virtual serverscenters on fears relating to the ability to successfullyback up and recover virtual machines (VMs). In fact, 44percent of the survey respondents said that concernsregarding VM backup and recovery prevented them fromvirtualizing mission-critical workloads.(The survey breaks out responses by region US, UK,France and Germany but the numbers cited in thisarticle refer to total percentages.)Not surprisingly, VMware vSphere is the leading virtualserver platform (73 percent), followed by MicrosoftHyper-V (28 percent) and Citrix Xen (27 percent). Thepenetration of both Hyper-V and Xen is expected toincrease to 30 percent over the next 12 months.What is surprising is that administrators are only backingup, on average, 68 percent of their virtual environments, 2 Back to Contents Backup for Virtual Environments a QuinStreet Storage eBook. 2011 QuinStreet, Inc.
