Advanced Protection: Ransomware Defense andlong-Term Archival

Inżynieria ransomware data is among the most valuable data an organization owns. A single ransomware event that critipts years of product development data can halt production indefinitely. Protecting this data requires a multi- layered security posture integrate with the backup architecture.

Hardening Backup Repositories Against Ransomware

Immutable storage is first line of defense. On- premise repositories can use hardened Linux repositories (like Veaem Hardened Repository or a Dell EMC Data Domain with immutability enabled) that prevent data frem being modified or deleted during a defined retention period.
