How to Set Up Offsite Backups - Complete Guide

Question: How do I keep backups offsite for disaster recovery?

Answer: Multiple offsite options available

Why Offsite Backups Matter

Benefits

  • Protection from site disasters (fire, flood, theft)
  • Ransomware protection (isolated from network)
  • Compliance requirements

Option 1: rsync to Remote Server

Step 1: Set Up Remote Server

# Install rsync on remote
apt install rsync
 
# Create backup user
useradd -m backupuser
mkdir /backup
chown backupuser:backupuser /backup

Step 2: Configure SSH Key Auth

# Generate key
ssh-keygen -t rsa -b 4096
 
# Copy to remote
ssh-copy-id backupuser@192.168.1.200

Step 3: Create Offsite Script

#!/bin/bash
# offsite-backup.sh
 
REMOTE="backupuser@192.168.1.200"
REMOTE_DIR="/backup"
 
# Sync all backups
rsync -avz --delete \
  /var/lib/vz/dump/ \
  $REMOTE:$REMOTE_DIR/
 
echo "$(date): Offsite backup complete" >> /var/log/offsite.log

Step 4: Schedule

# Cron job
crontab -e
 
# Daily at 4 AM
0 4 * * * /root/offsite-backup.sh

Option 2: Cloud Backup with rclone

Step 1: Install rclone

curl https://rclone.org/install.sh | sudo bash

Step 2: Configure Cloud

rclone config
 
# Follow prompts to add:
# - S3, Google Drive, Backblaze, etc.
