How to Set Up a Multi-Cloud Backup Strategy for Linux Servers

Storing all backups with one provider creates a single point of failure. A multi-cloud strategy ensures business continuity.

3-2-1 Rule for 2024

# 3 copies, 2 storage types, 1 different cloud
Local: /backups (NVMe on server)
Cloud 1: Backblaze B2 (cheapest for bulk)
Cloud 2: Cloudflare R2 (zero egress)

Multi-Cloud Backup Script

#!/bin/bash
DATE=$(date +%Y-%m-%d)
BACKUP="/backups/daily/$DATE"
mkdir -p $BACKUP
tar -czf $BACKUP/www.tar.gz /var/www
mysqldump --all-databases -u root -p'pass' | gzip > $BACKUP/databases.sql.gz
# Upload in parallel
rclone copy $BACKUP b2:yourserver/daily/$DATE &
rclone copy $BACKUP r2:yourserver/daily/$DATE &
wait && echo "Multi-cloud backup complete"
