Backing up your Windows computer is crucial in safeguarding your data. Whether you use Windows 10 or Windows 11, having a reliable backup strategy can save you from unexpected data loss. In this guide, we will explore how to back up your system using external hard drives and NAS (Network Attached Storage) drives.

Why Backup is Essential
Data loss can occur due to hardware failures, accidental deletions, or cyber attacks. Regular backups ensure that your digital life remains uninterrupted. With the right tools, you can easily restore your files, applications, and settings.
Using External Hard Drives
External hard drives are a popular choice for backups due to their portability and ease of use. Here’s how you can set up a backup using an external hard drive on Windows 10 and 11:

Backing Up with NAS Drives
NAS drives offer a centralized storage solution accessible by multiple devices. Here’s how you can use a NAS for backups:
- Ensure that your NAS is connected to the network and powered on.
- Access the NAS interface through your web browser using the device’s IP address.
- Configure a shared folder for backups.
- On your Windows PC, open Settings and go to Update & Security.
- Select Backup and click Add a network location.

Choosing Between External and NAS Drives
The choice between external hard drives and NAS depends on your specific needs. External drives are perfect for individuals and small backups, while NAS offers scalability and multi-device access, ideal for families and small businesses.

Enhancing Backup Security
To ensure your backups are secure, consider encrypting your data. Use built-in Windows encryption or third-party software to add an extra layer of protection. Regularly update your backup devices and software to guard against vulnerabilities.
