- Built-in software replication
- Array-based hardware replication
- Third-party app
- Third-party backup service
The first three answers received 21 percent of the vote each, and the final answer – third-party backup service – received the remaining 37 percent of the votes. The sample size was enough to be statistically significant, as a few votes would give a significant edge to one of the choices. Therefore, my take away was there was significant interest in all of the choices, although it is interesting that the cloud backup service was the most popular. It does seem that the choices offered by cloud service companies continue to permeate all different areas of IT. There was once a time when most companies thought that they would never put any of their data in the cloud, but that time has clearly passed. People are storing their primary data in the cloud, running their services in the cloud, and in this case using the cloud as a service to provide disaster recovery services to their VMs.
My initial thought when I saw the results of the survey was that it showed that there is no silver bullet that has proven itself to be the best way to do disaster recovery for VMs. If that were the case, there would be a clear winner and the “losers” would have very few votes. In contrast, all of the choices received a significant portion of the vote.
As I discussed in a previous blog entry, the choices of built-in software replication and array-based hardware replication each come with limitations when we’re talking about protecting VMware or Hyper-V VMs. Third-party backup applications and backup services can be very helpful, but they also come with an additional learning curve and cost.
The question posed in the webinar where the poll was conducted was whether or not things would be different if you used a hypervisor that had built-in data protection capabilities that did not come with the limitations mentioned in that other blog. If that sounds interesting to you, then you should check out the webinar DR strategies for VM’s. It is available on demand at this link.
