How to Automatically Backup a Linux Server (Daily & Secure Cron Jobs)

Backups aren’t optional — they’re your lifeline when something breaks. Whether you're running a game server, web platform, or production database, setting up automatic daily backups is one of the smartest things you can do.

In this guide, you'll learn how to back up your Linux server using cron jobs, secure those backups, and keep everything recoverable — without paying for complex backup tools.

Brought to you by Vastrox.com — helping developers deploy fast, stay secure, and protect their data.

Why Automate Backups?

Recover quickly after crashes, bugs, or accidental deletions
Protect against ransomware or malicious tampering
Keep project snapshots or client data secure
Create versioned archives of server states
Required for production-level hosting and compliance (especially when using Vastrox-managed deployments)

What You’ll Need

A Linux server (Ubuntu, Debian, CentOS, AlmaLinux, etc.)
Root or sudo access
Basic terminal/SSH experience
Space for storing backups locally or remotely

Step 1: Create a Backup Script

Let’s make a simple script to archive your key directories.

Create the script file:

sudo nano /usr/local/bin/server-backup.sh

Paste this example script (adjust paths as needed):

bash
CopyEdit
#!/bin/bash # Set variables DATE=$(date +%F) BACKUP_DIR="/backups/$DATE" SOURCE_DIRS="/etc /var/www /home" ARCHIVE="/backups/server-backup-$DATE.tar.gz" # Create backup directory mkdir -p "$BACKUP_DIR" # Copy files cp -r $SOURCE_DIRS "$BACKUP_DIR" # Create compressed archive tar -czf "$ARCHIVE" -C /backups "$DATE" # Cleanup temporary folder rm -rf "$BACKUP_DIR"

Save and close the file.
Make it executable:

sudo chmod +x /usr/local/bin/server-backup.sh

This script will back up /etc, /var/www, and /home into a dated .tar.gz file.

Step 2: Schedule the Backup with Cron

To run the script daily:

Edit the crontab:

sudo crontab -e

Add this line at the bottom:

0 3 * * * /usr/local/bin/server-backup.sh >/dev/null 2>&1

This runs the backup every day at 3:00 AM.

You can adjust the time as needed.

Step 3 (Optional): Sync Backups to a Remote Server

Want off-site backup storage? Use rsync to send it to another machine:

Add this line to your script:

bash
CopyEdit
rsync -az /backups/server-backup-$DATE.tar.gz user@remote-ip:/home/backups/ 

Make sure the destination server allows SSH access and that you use SSH keys for authentication.

Step 4: Secure Your Backup Storage

Store backups in a non-public directory (e.g. /backups not /var/www)
Use chmod 600 or stronger for .tar.gz files
Encrypt backups if they contain sensitive data (using gpg or openssl)
Consider rotating backups weekly/monthly to avoid disk space bloat

Best Practices

Don’t rely on just one backup — use multiple locations
Test your backup recovery process monthly
Monitor backup size and schedule cleanup (e.g. auto-delete files older than 7 days)

Example cleanup cron job:

find /backups/*.tar.gz -mtime +7 -delete
