Resilient Data: Architecting a 3-2-1-1 Backup Strategy for MSPs
In modern infrastructure, “Backup” is not a task—it is a foundational pillar of security. For an MSP managing hundreds of endpoints, a simple file-copy isn’t enough. Here is how I architect systems to survive ransomware and site-wide disasters. 1. The 3-2-1-1 Framework I advocate for an evolved version of the classic 3-2-1 rule, specifically designed for remote-first workforces: 3 Copies of Data: Primary, local secondary, and offsite tertiary. 2 Different Media: Utilizing localized NAS storage for fast LAN recovery and cloud-native repositories. 1 Offsite Location: Ensuring data is physically separated from the primary site. 1 Immutable Copy: Utilizing S3 Object Lock or Air-gapping to ensure backups cannot be deleted by compromised credentials. 2. The Infrastructure Stack My preferred approach utilizes a unified management plane to reduce “Shadow Data”: ...
