Disaster Recovery & Backup Engineering: ZFS Snapshots & BorgBackup
Reviewed by Cloud Infrastructure & Hosting Architecture Editorial Board
Executive Summary
Implementing the 3-2-1 backup rule: copy-on-write atomic filesystem snapshots, deduplicated client-side encrypted Borg archives, and immutable S3 object locks.
A robust disaster recovery framework ensures zero data loss and near-zero Recovery Point Objective (RPO) even in the event of catastrophic datacenter outages or ransomware.
1. The 3-2-1 Backup Implementation
- 3 Copies of Data: Primary production NVMe, local on-site secondary backup, and off-site cloud repository.
- 2 Different Media Types: Fast local block volume + remote S3 object storage with Object Lock enabled.
- 1 Immutable Off-Site Copy: Write-Once-Read-Many (WORM) storage preventing unauthorized deletion or encryption.
