Windows 3-2-1 Backup Strategy

A Windows Server backup strategy should follow the 3-2-1 rule to ensure data safety through redundancy, with a mix of full and incremental backups stored both on-site and off-site. While Windows Server Backup (WSB) is an integrated tool for this purpose, a comprehensive strategy may also benefit from third-party solutions for advanced features. 

Best practices for a Windows Server backup strategy

Implement the 3-2-1 backup rule

This widely recommended strategy is the foundation of a robust backup plan. 

• 3 copies of your data: Maintain your original data and create at least two backups.
• 2 different storage media: Use two distinct types of storage media for your copies, such as an internal hard drive, an external hard drive, or a network-attached storage (NAS) device.
• 1 copy off-site: Store at least one of your backups in a different physical location to protect against local disasters like fire or theft. Cloud storage is an excellent option for this. 

Combine backup types and schedule them

A smart schedule uses a mix of backup types to minimize resource impact while providing solid recovery points. 

• Full backups: A full backup creates a complete copy of all selected data and is resource-intensive. Run these on a regular schedule, such as weekly.
• Incremental backups: An incremental backup captures only the data that has changed since the last backup of any type. These are smaller and faster, making them ideal for frequent, even hourly, backups.
• Differential backups: A differential backup captures all changes since the last full backup. This requires more storage than incremental backups, but offers a faster restore process since fewer backups need to be “pieced together”. 

Automate and monitor the process

Automation reduces human error and ensures consistency. Monitoring confirms that the process is successful. 

• Automate your backups: Use WSB’s scheduling wizard or the wbadmin enable backup command-line tool to automate your backup jobs.
• Monitor backup reports: Check for success or failure reports and review logs to catch potential issues early.
• Test your restores: Regularly test your backup restores to verify that the data is recoverable and uncorrupted. Document your recovery procedures so they can be followed during a crisis. 

Consider third-party solutions

While WSB is a capable, built-in tool, third-party software offers more advanced features for complex needs. 

• Enhanced flexibility: Third-party options often provide more granular control, such as backing up individual files on a volume without needing to back up the entire volume.
• Advanced features: Many commercial products offer enhanced security (like immutable backups), better compression, faster restores, and robust reporting.
• Scalability: Third-party solutions are typically more scalable as your organization’s infrastructure and data volumes grow.

How to use Windows Server Backup (WSB)

Install the feature

1. Open Server Manager and select Add roles and features.
2. Follow the wizard to the Features screen, and select Windows Server Backup.
3. Complete the installation. 

Configure your backup

1. Open Windows Server Backup from Server Manager > Tools.
2. In the Actions pane, select Backup Schedule to launch the wizard.
3. Define your backup type (full server or custom) and schedule the frequency and time.
4. Specify a destination, such as a dedicated local volume or a remote shared network folder. 

Perform a full server recovery

1. Boot the server using the Windows Server installation media and choose Repair your computer.
2. Navigate to Troubleshoot > System Image Recovery.
3. Select your desired backup image to restore from.
4. Follow the wizard to reformat disks and complete the recovery.
