Veeam: Backup, But for Virtual Machines

The rise of virtualization has ushered in dramatic shifts in the computing landscape: Servers are more efficient and users can be more agile. But it's also created new challenges for backup and recovery.

Network World — The rise of virtualization has ushered in dramatic shifts in the computing landscape: Servers are more efficient and users can be more agile. But it's also created new challenges for backup and recovery.

Instead of having a single server that can be backed up to a tape library weekly, for example, now a handful or more of virtual machines are spread across a server and they can be spun up and down within minutes. Backing up to tape doesn't work in that environment.

Neither does an agent-based approach, another traditionally popular backup method: The agent sits on the machine and backs it up to a storage library. Agents add overhead in the form of an unnecessary application running on the VM. "Existing backup hasn't grown with the advancements in computing," Veam Vice President of product strategy Doug Hazelman says. "There's an opportunity to exploit the power of virtualization for backup."

Veeam backs up VM images instead of using an agent to back up files. In the event of a disaster, virtual machine images that are stored in a central location can be rebooted almost instantly. Veeam's software runs through the hypervisor - currently VMware and Microsoft Hyper-V are supported - and takes snapshots of virtual machine images. After an initial full backup, the software then uses caching and deduplication processes to only store new information in the VM images.

Since being founded in 2006 the company has seen impressive growth. It boasts more than 20,000 resellers, which account for most Veeam sales. It has about 80,000 customers and this year has hit a quarter of a billion dollars in revenue. This week the company announced that its Veeam Cloud Provider program, which is the license for cloud service providers to offer the Veeam software, has surpassed 7,000 members. The company cites notable traction in the European market, including at OVH, one of the region's largest web hosting companies.

Employing this image-based approach allows Veeam and its partners to offer customers unique platforms for using the backed up images. Some customers use the backed up or replicated VM images as a test and development lab, allowing changes to software to be practiced without impacting the production environment. Other cloud providers are able to offer less than five-minute guaranteed backups in their service-level agreements with full VM backups using Veeam's software.
