#### Executive summary This Arctic Wolf guidance piece explains why clean, recent, and restorable backups are critical to recovering from ransomware and related cyber incidents, outlines common backup types (on-prem disk, tape, cloud, offsite), recommended cadences by asset type, and promotes the 3-2-1-1-0 best practice; it also details how backups fit into incident response (preparation, detection, containment, recovery, and post-incident updates) and warns that attackers frequently exfiltrate data and target accessible backups via remote-access vectors.
