Backup, disaster recovery, and business continuity have changed quite a bit over the years, and they will continue to change into the future as more capability, analytics, and functionality are added to the general family of data protection tools. As we launch ourselves into the clouds, we need to perhaps rethink how we do data protection, what tools are available for data protection, and how to use our older tools to accomplish the same goals. We need an integrated data protection plan that not only accounts for cloud or data center failures but also accounts for the need to run within the cloud. There is always the need to get your data there and back again. Continue reading The Face of the New Backup
During the last two Virtualization Security Podcasts, the panel discussed backups as well as scripting related to backups and in general. We went further to discuss the security implications surrounding backups, including whether or not a recovery is required when a site is hacked. The latter raises an important question: what constitutes a disaster that requires recovery? Is recovery needed only for catastrophic failure (which TVP has experienced)? Is it required in response to malfeasance from a disgruntled employee? To an external cyber-attack? Do you classify cyber-attacks as disasters requiring restoration from known-good sources and restoration of data from a backup, or do you use some other means to recover?
Recently, we experienced a fairly catastrophic SAN failure: we lost two drives of a RAID-5 array. Needless to say, recovery was time-consuming, but it also pointed out some general issues with many disaster recovery, business continuity, and general architectures involved with virtual environments. Luckily, we were able to start one of the drives, let the hot-spare take over for the second failure, and recover the vast majority of our data. Yes, there was corruption, so that is where our backups came in and the ultimate dependencies for restoration. How do you recover from a catastrophic failure? Do you fail over automatically to a hot-site or cloud environment? Even if you fail over, how do you recover from a catastrophic failure?

VMware has been aggressively building and executing its hybrid cloud vision, extending the cloud outside of the data center. In line with this vision, VMware recently announced an expansion of its VMware vCloud Hybrid Service by adding disaster recovery as one of its offered services. This expansion will put VMware in direct competition with companies like IBM, Sungard AS, Amazon, Rackspace, Zerto, and others in the Recovery as a Service space.
Recently at Dell World, I was part of a conversation about what would be utopian disaster recovery and where we are today in the state of the industry. But where we are today is transforming, with a new name that encompasses many technologies. We are now using the term “data protection” (DP) to mean much more than just disaster recovery (DR), backup, business continuity (BC), replication, data loss prevention, and replication, but also the basic functions of confidentiality, such as encryption. The main goal of data protection is to provide a way to use your data as quickly as possible wherever it is needed and with minimal or no loss. Continue reading Utopian Disaster Recovery
Data protection of the future: What will it look like? Will we have huge amounts of storage in just one place, or will we have myriad data everywhere? The more copies the better, for example? Or are we moving toward a combination of the two? Can what we are doing today actually be used for data protection in the future? Think about how hybrid clouds are used today: do they grant us new forms of data protection? Continue reading Data Protection: The Future
