Revolutionizing backup and recovery for a virtualized infrastructure

Established in 1995, Sony Network Communications is a Japanese Internet service provider (ISP) operating under the brand names ‘So-net’ and ‘PostPet™’. It recently expanded to provide a range of B2B and B2C telecommunication services, and embraced new trends in technology, such as IoT.

As an ISP, Sony Network Communications stores a wide range of data, including user credentials, email messages, billing information, support requests, and system logs, across 2,000 VMware virtual machines. To ensure stable and resilient services, the company must quickly back up and restore this data in the event of a cyberattack or system outage.

“Previously, we relied on a legacy tool to take copies of application and system data but it was time-consuming to update the backup settings every time we added or removed a virtual machine,” says Ryohei Kiyoyama, Infrastructure Operation Section, IT Platform Department, System Engineering, Sony Network Communications Inc.

Sony Network Communications decided to simplify and strengthen backup and recovery by deploying a dedicated solution. It selected Commvault Complete™ Backup & Recovery due to its ease of use, rapid restore times, cost-effective licensing, and automation features.

Reducing backup times and volumes with deduplication

With the Commvault solution, Sony Network Communications can now automatically detect hundreds of changes made to virtual machines every year and update the backup target list without manual intervention. This significantly reduces the workload for daily backup operations and enables the IT team to focus on other valuable tasks.

“By blending incremental and full backups with Commvault, we achieved a deduplication rate of 86 percent and reduced the volume of backup data by 80 percent. Such improvement allows us to store 400TB of target virtual machine data as just 80TB of backup data,” Kiyoyama explains.

The Commvault solution’s superior backup speed also cut the average backup window by 66 percent, helping the company conduct a weekly backup schedule and maintain the backup data for one month.

In addition, Commvault’s Professional Services team helped Sony Network Communications to implement the new data management solution quickly and seamlessly.

Cuts licensing costs and supports data growth

With data volumes increasing every year, Commvault’s socket-based pricing model has helped Sony Network Communications to lower licensing costs compared to its previous volume-based model. It also eliminates the risk of running out of storage capacity for backups.

The biggest advantage of the Commvault solution is its ability to adapt and scale with the company’s changing environment. Sony Network Communications plans to use the multi-tenant function to delegate data backup and restore to each business department to help them better manage their own needs.

The company is also investigating how Commvault can be integrated with its physical backup operations and be used to protect public cloud resources.
