Why Should You Backup Windows?

Here are some key reasons why you should backup your Windows regularly:

Restore after hardware failure – If your hard drive crashes or your laptop/PC stops working, a backup allows you to get back up and running quickly on new hardware.

Recovery from ransomware or malware – Malicious attacks can damage or encrypt your files. A backup gives you an untouched copy to restore from.
Undo accidental file deletion – We’ve all deleted a file by accident before. Backup gives you a safety net.
System rollback after a problematic update – Major Windows updates can sometimes cause issues. A backup allows you to revert back.

Migration to a new PC – When you get a new computer, you can transfer your entire system from a backup.

Regular backups provide peace of mind that your files, settings, and Windows installation are protected in case of unexpected issues.

Choosing an External Hard Drive for Backup

The first step is to choose an external hard drive that provides ample storage space for your backup. Here are some tips:

Storage capacity – Choose an external drive that is at least 1.5x to 2x the size of your PC’s hard drive. This provides room for multiple backup versions.
USB 3.0/3.1/USB-C – The faster the connection, the quicker your backup and restore process will complete.
Portable hard drives – Small portable HDDs with USB connectivity offer flexibility for storage and use with multiple PCs.

Desktop hard drives – Larger external drives that sit on your desk provide higher capacities for a full system backup.
NAS devices – Network attached storage can act as a centralized home for backups for all devices on your network.

Reliable hard drive brands to consider include Western Digital, Seagate, Toshiba, LaCie, and Samsung, among others. Avoid generic no-name hard drive brands.

Using Windows Backup Utility

Windows includes a free Backup and Restore utility that can create system image backups to an external hard drive. A system image contains your programs, system settings, files, and folders that can be restored all at once. Here are the steps to use it:

Connect your external hard drive to your computer via USB cable. Make sure the drive has ample storage for a system image backup.
Type ‘Backup’ into the Windows search box and select ‘Backup and Restore (Windows 7)’.

In the Backup and Restore Window, select ‘Create a system image’ on the left.
Check the box to backup onto an external hard drive and select your drive. Click Next.
Choose a backup location on your external drive and confirm. The initial backup will take time to complete based on your drive size.

Consider scheduling regular weekly backups by clicking on the ‘Schedule’ link.

The Windows Backup utility creates system image backups that can restore your entire system in case of hardware failure or OS issues.

Advantages of Windows Backup

Free and built into Windows – No need to install third party software.

System image backup – Backs up everything needed to recreate your PC setup.
Bare metal restore – Can fully restore to a new hard drive or device.
Scheduling – Automate backups to run on a regular basis.

Disadvantages of Windows Backup

No file versioning – Stores only the most recent system image.
Manual restore required – Must boot into the recovery environment to restore files.
Slower than some 3rd party options – Large backups can take significant time to create.

Confusing interface – Some find the Windows Backup menus hard to navigate.

For simple backup needs, the built-in Windows Backup provides a basic system image utility. Power users may prefer more advanced third party backup tools.

Using Macrium Reflect

Macrium Reflect is a popular free backup program for Windows that offers robust options for complete system imaging. Here is how to use it to backup your system:

Download and install Macrium Reflect on your PC after creating your external hard drive backup destination.
Open Macrium Reflect and select ‘Create Backup Image’. Choose where you want to save the backup.
Select the disk partitions to backup. Choose the entire system disk to backup everything.

On the summary screen, click finish to begin the initial backup to your external drive.
For scheduled backups, select the ‘Schedule’ tab and choose daily, weekly, or monthly backups.
To restore in the future, boot to the Macrium recovery environment and navigate to your backups.

Macrium Reflect also maintains backup version history and provides advanced backup management options.

Advantages of Macrium Reflect

Retains multiple backup versions – Helpful for restoring previous system states.
Scheduled backups – Set and automate backup schedules.

Backup validation – Checks backup integrity to identify issues.

Compression – Storage saving backup compression.

Disadvantages of Macrium Reflect

No mobile app – Managing backups requires a PC with the program installed.
Potential licensing costs – Free for personal use but business licensing required.
Steeper learning curve – More complex than Windows Backup.

For people who want to maintain multiple backup versions and streamlined disaster recovery, Macrium Reflect is an excellent choice.

Cloning Your Hard Drive

Another way to create a backup of your Windows system is to clone your entire hard drive. Cloning replicates the exact structure of your original drive onto backup external media. Popular free cloning tools include Macrium Reflect, Clonezilla, and AOMEI Backupper. Here are the basic steps:

Connect your external hard drive backup drive with adequate capacity.

Open your cloning software and select the option to clone a disk.
Choose your computer system hard drive as the source disk to clone.
Select your connected external hard drive as the destination disk.

Wait for the initial cloning process to fully copy your hard drive contents to the external media.
Schedule incremental clones to capture updates on a routine basis.

Cloning creates an exact replica of your working system to restore when needed. Keep the clone backup current with regular incremental clones to capture system changes.

Advantages of Cloning

Boots just like your original drive – Allows you to quickly resume work.
Contains a replica of all partitions – Makes your backup completely comprehensive.
Allows for fast mass deployment – Good for IT teams deploying standard setups.

Disadvantages of Cloning

Requires re-cloning after restore – Originals lost after restore.
Storage space intensive – Duplicates all data including free space.
Lengthy initial clone time – Can take hours for large hard drive capacities.

For people who want a bootable backup that mimics their existing system, drive cloning can be a good solution.

Using File History

The Windows File History tool provides versioned backup copies of files, folders, and libraries in a continuous manner. While it doesn’t backup your whole system, it protects your important personal data. Here is how you can use it:

Plug in an external hard drive with ample capacity.

Go to Settings > Update & Security > Backup in Windows 10/11.
Select ‘Add a drive’ and choose your external drive for backups.
Toggle ‘Automatically backup my files’ to On to enable auto backups to run periodically.

Under ‘More options’ you can exclude folders or change backup frequency.
To restore files, open File History and look for previous versions of a file.

File History is useful for home users who want a protected copy of work documents, photos, music, videos, and other personal files.

Advantages of File History

Backs up personal files automatically – Provides ongoing protection.
Allows granular restores – You can restore only the files you need.
Built into Windows – Simple to enable.

Versioning – Restores previous copies of files.

Disadvantages of File History

No system image backups – Only protects personal files.
Slow initial backup – Can take time for large media libraries.

Folder exclusive approach – You must choose what to protect.

File History gives continuous backup protection for documents and media without backup up your whole system.

Using Third Party Backup Software

In addition to the built-in Windows tools, many excellent third party backup programs are available. Top options include:

Acronis True Image – Offers full disk imaging, file/folder backup, and mobile device access.
