How to Back up Computer? What's the Best Way for Computer Data Backup

Updated by Daisy on May 28, 2021

In our daily lives, we spend most of our time using a computer, and most data are kept on them. Digital data are prone to be lost due to various causes such as hardware issues or accidental file deletion. When one such incident happens, it will save you the trouble if you have backups of the missing data ready. So computer users must keep regular backups of their important files.

Part 1: The Importance of Computer Data Backups

Apart from protecting against sudden data loss, keeping backups of your files can also be beneficial in other ways. You can save multiple backups for each version of the file, allowing you to revert a file to a previous version if you encounter an issue or made a mistake when editing it.

Keeping backups is not limited only to files and folders; You can create backups of an entire partition, a disk, or the operating system using reliable backup software. By keeping the second copy of your computer's data, you will restore everything to normal even if the system is damaged or destroyed.

The process of backing up data can be done in multiple ways, such as manually copying needed files, syncing files to cloud storage, or using software to store copies of necessary data automatically. In this article, we will show you how to backup files using these three methods while comparing the advantages and limitations of each one.

Part 2: List of Ways to Backup a Computer

As mentioned above, there are multiple approaches to data backup, which we will compare in the list below. We recommend that you use reliable backup software like EaseUS Todo Backup to automatically backup your files, system, and disks into a hard drive, external device, or cloud storage. With this tool, you can easily schedule your automatic backup, encrypt confidential files, compress backup images, clone your operating system, and much more.

Simple methods are generally only used for backing up individual files and folders. Users looking to clone a hard disk partition or the operating system may refer to Method 3 for detailed guides on EaseUS backup software.

Method 1: Copy to External Hard Drive or USB Drive

The simplest way to back up your files is to copy them into another device, such as an external hard drive or a USB drive. While this method is simple and quickly done for users that only want to back up a few files or folders, it may be inefficient if you need to back up large amounts of data regularly.

backup data to external hdd

Time spent copying files depends on the external device and the connection type used to transfer data. I recommend an external SSD used and connected through the computer’s USB 3.0 port for better write speed.

Step 1. Locate all files and folders that you want to backup.

Step 2. Copy and Paste (or click and drag) the files into your external hard drive or USB drive.

Step 3. Once finishing the copying process, safely eject the device.


· Simple and intuitive

· Easily done and efficient for small files


· Is time-consuming and not suitable for regular backup of larger files

· Risks running into errors when copying

· Prone to user error when selecting files to copy

Method 2: Backup via Cloud Storage and File Sync

There are many free and accessible cloud storage services such as Dropbox, Google Drive, OneDrive, which you can use to store important files. With some services, you can sync files across multiple devices, keeping your data secure if one of your devices becomes inaccessible.

Users looking to store large amounts of data on the cloud may have to pay for storage capacity upgrades, depending on the service used. A slow internet connection can impede file transfer and cause syncing failure. You will also have to download the files to your device beforehand if you want to access them while offline.

cloud backup services

Accessing cloud storage can vary for each service mentioned above and others. For example, here are the steps to use Google Drive

Step 1. Go to Google Drive on your web browser

Step 2. Log in with your Google account or register one

Step 3. Upload files or create new files as needed

You can access your drive on mobile devices by installing the Google Drive application and log in with the Google account used above.


· Easily access your stored files from any device

· Any edits are synced to the cloud immediately


· Limited storage for free services

· Requires stable internet connection to function properly

Method 3: Use a Backup Software to Backup the Computer Data

Alternatively, you can install backup software to manage your important data easily automatically. This method is suitable for all beginners looking to backup files to an external hard drive. You can also choose to backup an entire hard drive partition or the operating system as a whole with a few simple clicks.
