Two for Tuesday: Go Cloud + Traditional Backup Mistakes
It’s Twofer Tuesday, where we like to highlight two relevant articles on disaster recovery planning, data replication and DR to the cloud. This week’s choice quotes:
Yes, the cloud provides “a new alternative for disaster preparedness.”
“One of the biggest mistakes is trying to protect a virtual infrastructure with traditional backup methods.”
Jill Yaoz CEO of AFCOM, the “association of data center management professionals,” writes in Forbes about the importance of a disaster recovery plan and strategy. She goes on to highlight the cloud as “a new alternative for disaster preparedness.”
“As with any new technology, the DR team must be vigilant in staying on top of trends and new developments. Running comprehensive DR drills to ensure the failover happens as planned with minimal disruption to the end user will be an imperative. Through the cloud, an IT organization can have all of the benefits of a hot backup site without the expense and waste of underutilized compute and infrastructure resources.”
Another article this week, by Stacy Collett of Computerworld highlights the complications when virtualization meets backup / DR.
“More than a quarter (27%) of the respondents in the Computerworld poll said that server virtualization has complicated backup and disaster recovery.”
Collett goes on to quote Jeff Boles, senior analyst at Taneja Group in his article:
“One of the biggest mistakes here is trying to protect a virtual infrastructure with traditional backup methods,” according to Boles. With traditional backup, “the degradation and backup performance is more than a linear degradation as you scale the number of virtual machines on a piece of hardware. You’re effectively creating a blender for backup contention as you’re trying to protect these virtual servers overnight. You try to do 10 backups simultaneously on this one physical server, and you’ve got a lot of combat going on inside that server for memory, CPU, network and storage,” he says.
The article continues:
“Complicating matters are workload mobility tools, such as VMWare’s Storage vMotion, that let users relocate virtual machine disk files between and across shared storage locations. “Now you have to keep a backup going in relation to these virtual servers that are going to be moving around, and possibly run into other bottlenecks. That can be a serious headache,” says Boles.
It’s a headache many of our customers are seeing when using both backup & replication solutions, one that pushed us toward a hypervisor-based approach to recovery & replication — keeping the full range of virtualization tools (such as VMWare’s Storage vMotion) in mind — replicating seamlessly despite frequently-moving data and VMs.
