ExaGrid Tiered Backup Storage provides all four lines of defense:
A second backup/data protection repository tier that is not network-facing (creating a tiered air gap) so it is not visible to threat actors.
A delayed delete policy. When data is deleted by the threat actor on disk, deduplication appliances, and even ExaGrid’s network-facing Landing Zone, the data is not immediately deleted in ExaGrid’s non-network-facing Repository Tier. This allows you to freeze the ExaGrid system so the delayed delete will stop counting down, giving you plenty of time to recover.
AI-powered ransomware recovery. ExaGrid’s Auto Detect & Guard feature uses AI and monitors all daily operational deletes, trains/learns, and creates patterns. If a delete request is outside of the pattern, the customer’s IT team is alerted and ExaGrid automatically extends the delayed delete policy so data in the Repository Tier is never deleted. If the delete was an operational delete, the IT team can clear the alert and ExaGrid will return to the original delayed delete policy.
All of the current and long-term retention data is deduplicated for storage cost savings, and all objects are immutable meaning they won’t be changed, modified, or deleted.
To truly ensure recovery, the most important functionality needed is a non-network-facing tier (tiered air gap) with delayed deletes. Immutable data objects are also crucial, but are not enough by themselves.
