[Full Guide] How to Configure cPanel Backup to S3

This process requires the use of WHM services and is mainly divided into the following 4 parts.

Part 1. Preparing for cPanel Backup to S3

Before jumping in, let’s get you prepped.

What You’ll Need

• Access to your cPanel/WHM
• An AWS account
• An S3 bucket
• Your S3 access and secret keys

Setting Up Your Amazon S3 Bucket

1. Log into your AWS Console.

2.Go to S3 > Create Bucket.

3. Give it a name and choose a region.

4. Disable "Block All Public Access" (since backups are private, this is fine).

5. Click Create.

Part 2. Configuring cPanel to Backup to S3

Here’s where the magic happens. Let’s get your cPanel/WHM to talk to S3.

Step 1: Enable Backup Configuration

1. Log into WHM.

2. Search for "Backup" and go to Backup Configuration.

3. Check Enable Backups.

Step 2: Set Backup Settings

• Choose compressed, uncompressed, or incremental backups.
• Set your backup retention period. Pick the days you want backups to run.
• Choose whether to back up accounts, system files, etc.

Step 3: Add Destination – Amazon S3

1. Go to Additional Destinations.

2. Click Create New Destination.

3. Select Amazon S3.

4. Add your S3 Bucket name, Access Key, and Secret Key.

5. Set a directory path (like /backups).

Step 4: Validate and Save

Click on "Save and Validate Destination". If everything’s good, you’ll see a green checkmark.

Part 3. Automating cPanel Backup to S3

Because manual backups? Ain’t nobody got time for that.

Using cPanel’s Built-in Scheduler

cPanel’s backup system lets you schedule daily, weekly, or monthly backups. Just set it once and forget about it.

Setting Up Cron Jobs

While WHM handles automation, some users prefer control via cron jobs.

Example cron:

0 2 * * * /scripts/pkgacct username /home && aws s3 cp /home/cpmove-username.tar.gz s3://your-bucket/backups/

Using Scripts or Plugins

You can also automate via third-party plugins or bash scripts using AWS CLI. This is ideal if you want detailed logging or additional processing like compression or encryption.

Part 4. Verifying Backup Success

Trust but verify, right?

Test Restore Process

Download a backup and try restoring it on a test server. Better to find out issues now than during a crisis.

Check File Integrity on S3

Log into your AWS console and make sure your files are:

• Present in the correct folder
• Not corrupted
• Properly timestamped

Common Issues and How to Fix Them

Even the smoothest setups can hit a snag.

Connection Errors

• Double-check S3 credentials.
• Make sure the bucket name is correct.
• Ensure your server’s time is synced (important for AWS auth).

Permission Denied Problems

• IAM user must have s3:PutObject and s3:ListBucket permissions.
• Test with AWS CLI to confirm access.

Backups Not Showing Up in S3

• Confirm the backup job completed.
• Check logs in /usr/local/cpanel/logs/backup/.
• Verify the destination path is correct.

Best Practices for cPanel Backup to S3

Use Versioning

Enable S3 versioning so if a backup goes wrong, you can restore a previous version.

Monitor Storage Costs

S3 charges based on usage. Set up storage lifecycle rules to auto-delete old backups.

Encrypt Your Backups

Turn on encryption (either client-side or server-side) to protect your data from prying eyes.

Final Thoughts

Backing up your cPanel to S3 isn’t just about peace of mind—it’s about being smart and proactive. With just a few steps, you can automate the entire process and sleep better knowing your website is protected. Whether you’re running a blog or a business site, don’t wait for disaster to strike.
