The Business Challenge

The IT team at TK Telekom supports daily business functions and more than 1,000 associates; therefore, the team’s disaster recovery (DR) strategy is the centerpiece of its operation. 

According to Łukasz Rakowski, Manager of the IT department at TK Telecom, he and his colleagues virtualized 40% of their IT infrastructure on VMware vSphere as part of an overall effort to improve DR. They oversee approximately 100 Windows and Linux virtual machines (VMs) that run important systems and applications.

“Virtualization is great, but we ran into problems protecting our VMs and their data,” Rakowski said. “VM backups were unreliable and granular recovery was difficult. We also knew it was important to replicate VMs to our other data center, but we didn’t have the means for replication. How could we virtualize more of our infrastructure without reliable VM protection?”

Rakowski and his colleagues contacted Comtegra, a leading systems integrator in Poland, for advice. Comtegra helps companies manage their data at every stage. “Given TK Telekom’s needs, we recommended Veeam,” said Tomasz Mężyński, Account Manager for Comtegra. “Veeam offers fast and reliable backup and replication and granular recovery. It also offers tight integration with EMC Data Domain, which TK Telekom uses for data storage.”

The Veeam Solution

Veeam® Backup & Replication™ quickly became a key component of the DR strategy at TK Telekom. It combines image-based backup and replication in a single solution and provides fast, flexible and reliable recovery of virtualized applications and data for VMware vSphere and Microsoft Hyper-V. Veeam is used by more than 45,000 customers worldwide and protects more than five million VMs. It provides the most comprehensive protection for virtual environments.

“Veeam gives us the confidence to continue virtualizing critical systems and applications for several reasons,” Rakowski said. “For example, recovery is quick and easy, which enables us to meet our recovery time objectives (RTOs) of 24 hours or less. We find that file-level recovery with Veeam is at least 10 times faster than our previous method.”

Rakowski said VM backups are faster with Veeam too. Lightening-fast incremental backups minimize backup time for the IT team, enabling it to back up more frequently and improve recovery point objectives (RPOs). Backups also require onethird less disk space at TK Telecom because of Veeam’s built-in deduplication. Plus, Veeam works with any storage solution, regardless of the provider, so it integrated well with Data Domain at TK Telecom.

Another key differentiator about Veeam is that it offers VM backup and replication in the same product. Not only can IT administrators back up their VMs, they can also perform image-based replication on-site for high availability or off-site for DR. With Veeam’s near-continuous data protection (CDP), if a VM goes down, administrators can immediately fail over to a replica and then fail back.

“Replication is a really important feature for us,” Rakowski said. “Veeam makes it easy to replicate VMs to our other data center, fail over and fail back, which minimizes the risk of data loss.”

The Results

Fast, reliable VM backup and recovery improve DR strategy
Since VM backup is five times faster with Veeam, TK Telekom’s IT team backs up more frequently for improved RPOs. The team improved RTOs with Veeam’s granular recovery.

VM replication minimizes risk of data loss
Veeam offers two features in one product: backup and replication. The IT team replicates VMs between data centers to achieve near CDP.

Built-in data deduplication reduces backup storage consumption
Both Data Domain and Veeam Backup & Replication reduce disk space requirements for backups. Their deduplication technologies complement each other for maximum utilization.
