Groton Utilities Provides Comprehensive Data Protection with DXi, Scalar Tape, and Veeam
We received great help from Quantum when we initially set up the DXi, and a very quick response when an issue arose with the Scalar i40. We called one day, and the Quantum service guys showed up the next morning. They replaced not only the drive that had failed, but the other drive in the library as well. That was great service.

Tape Component Delivers Critical Protection Against Ransomware

“We have long been committed to a 3-2-1 approach to protection,” says O’Farrell, “but it took quite a bit of work to make sure we have at least three copies of data, in two different locations, with one copy off-site.” Tape is a critical component for the IT team to provide important protection against malware. “We have seen the damage and costs that recent ransomware attacks have created, and we know the best protection is having a kind of ‘air gap’—keeping a copy of critical data on tape that is isolated from the vulnerable spinning disk.”

The IT team created a configuration using the two different data centers to provide redundancy and failover capability, and the replication capability of its EMC storage arrays to create copies of the primary data in CIFS shares across the two locations. Veeam backs up the VMs to the DXi appliance with secondary backup copy jobs written to the CIFS shares, and the team’s legacy backup application creates tapes from the replicated CIFS shares for the final level of protection.

Reducing Complexity for the Next Stage

“It works,” O’Farrell explains, “but it is too complicated for me. There are still too many steps and vendors involved. Replicating primary data between sites takes lots of bandwidth that we could use for other things, and we have ended up using two different backup applications.” To simplify and reduce network loading, the IT team is planning to rework the backup system in the future.

“We are going to add a second DXi and install it at the second data center,” O’Farrell explains. The plan is to back up everything— both VMs and CIFS shares on physical servers—to the DXi appliances using Veeam and replicate the backup data between data centers using the DXi instead of the existing arrays. “Replicating backup data between DXis is a much better option. It will use a small fraction of the bandwidth that we need now— less than a tenth—and it will eliminate one additional job that the primary arrays carry out now.”

As part of the next stage, Groton Utilities will leverage integration of the DXi with the Veeam Data Mover protocol—a recent announcement that enables even faster backup and restore performance, supporting advanced Veeam features like synthetic full backup and Instant VM Recovery directly on a DXi appliance.

The team will also consolidate backup vendors, use Veeam to back up the remaining physical servers, and create tapes for all the data that needs that level of protection. “Good technology is letting us simplify. The DXis are getting very good dedupe rates and offer very effective replication. Veeam can now do backups for both VMs and physical servers, and it can write data both to CIFS shares and to tape libraries. Our experience over the last year is that Veeam and DXi work very well together.”

Effective Service Provides Confidence

As with many small and medium sized organizations, Groton Utilities’ small IT staff handles everything from applications support and servers to networks and backup. “Anything we can do to improve operational efficiency is really key to letting us provide better service and keep overall costs as low as possible,” says O’Farrell. Having strong service for critical equipment is one of the important factors, and Quantum has been exemplary. “We received great help from Quantum when we initially set up the DXi, and a very quick response when an issue arose with the Scalar i40.”

At one point, one of the drives in the Groton tape library failed and needed replacing. “We called one day, and the Quantum service guys showed up the next morning. They replaced not only the drive that had failed, but the other drive in the library as well. That was great service.” On another occasion, a large-scale power outage in one data center caused most of the equipment to shut down. When the power came back on and devices started booting up again, the Quantum remote service team saw the start-up sequence and contacted the Groton IT team to make sure that everything went smoothly during the restart. “They actually called us before we noticed what was happening, and helped us get everything back up and working cleanly. It was great.”
