Secure ExaGrid System Allows Team to Sleep Better at Night
René Oogink, senior technical specialist, has been working at Gemeente Hengelo for over 14 years. Prior to ExaGrid, the municipality had used a NetApp system that was scripted to make snapshots with an advanced scheduling principle. It was designed to do the backups writing to disk, and then it was synchronized to another data center as a secondary DR location.
“We not only needed a new storage system, but I also wanted to introduce a new way of performing backups. I didn’t want to use the advanced custom scripting because it was unmanageable. I wanted to use a standard backup solution with standard hardware. I introduced the tech team to Veeam and ExaGrid. We demoed some other vendors, including IBM TSM and Commvault, but in the end, our vendor advised us to use Veeam in combination with ExaGrid. This resulted in us having the best solution currently in the market,” he said.
At the time when Gemeente Hengelo installed ExaGrid, many other municipalities had faced malicious attacks from hackers. “We wanted to find a system that could ensure our data would not be erased. ExaGrid’s Retention Time-Lock feature with immutability had just been released, so it was perfect timing. Our neighboring municipality had a big problem, but we could sleep well knowing that our data was safe and ready for recovery if needed.”
ExaGrid appliances have a network-facing disk-cache Landing Zone where the most recent backups are stored in an undeduplicated format for fast backup and restore performance. Data is deduplicated into a non-network-facing tier called the Repository Tier, where recent and retention deduplicated data is stored for longer-term retention. The combination of a non-network facing tier (tiered air gap) plus delayed deletes and immutable data objects guards against the backup data being deleted or encrypted. ExaGrid’s offline tier is ready for recovery in the event of an attack.
