ExaGrid Releases AI-Powered Retention Time-Lock for Ransomware Recovery

ExaGrid, the industry’s only Tiered Backup Storage solution with AI-Powered Retention Time-Lock (RTL) that includes a non-network-facing tier (creating a tiered air gap), delayed deletes and immutability for ransomware recovery,  announced the release of a new AI-Powered RTL feature: AutoDetect & Guard. The AutoDetect & Guard feature 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. This provides two benefits: an early warning of a possible cyber-attack where the attackers are trying to delete the backup data and ensuring that the backup data is not deleted on ExaGrid’s non-network-facing Repository Tier.

ExaGrid Tiered Backup Storage 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, for longer-term retention. ExaGrid’s unique architecture and features provide comprehensive security including Retention Time-Lock for Ransomware Recovery, and through the combination of a non-network-facing tier (creating a tiered air gap), a delayed delete policy, and immutable data objects, backup data is protected from being deleted or encrypted. ExaGrid’s offline tier is ready for recovery in the event of an attack.
