(2024) An Ultimate Guide to Backup Hard Drive and Restore Your Computer

Creating regular backups should be one of the most important tasks that computer users should never neglect. Many people have experienced data loss or system crash due to hard drive failures, so backup hard drive is always the best way to protect your irreplaceable files from any disasters.

*Here, backing hard drive refers to backing up a computer's hard drive, which can be a separate system drive or an entire hard disk drive with multiple partitions on your computer.

Ⅰ. What Is Hard Drive Backup? Learn Backup Basics

A backup is a second copy of your important data files, photos, music, and documents that you store in a separate location from the originals. The purpose of having backups is to be able to retrieve the backup data in case the originals are lost or corrupted.

There are mainly four different ways to backup computer hard drive data:

1. ?Copy and Manual Transfer: You can backup data manually by copying it from one location to another (e.g., from your computer hard drive to an external hard drive or cloud storage).
2. ?Backup Through Advanced Software: You can also use professional backup software that automates the process of creating backups and typically offers additional features, such as scheduling backups, incremental backups, and more.
3. ?Use a Specific Backup Hard Drive: Some hard drives are exclusively designed for backup and sync purposes. For example, Seagate HDD and SSD can automatically backup all your important files from your computer to your storage device via its shipped Seagate Toolkit app on a PC or Mac.
4. ?Clone a Hard Drive: Cloning a hard drive means creating an exact replica of your existing hard drive, which can be used as a backup in case your original hard drive crashes or fails.

We know that doing computer backup is not a once forever thing. Instead, to make useful backups of a designated hard drive should be done regularly. To ensure the backup frequency, in order to decrease disk usage for storing the growing backup files and improve the recovery speed from a critical backup, there are three types of hard drive backups that can help us achieve the best backup experience.

There are three types of backup that serve different backup purposes:

1. ?Full backup: This type of backup copies all selected files regardless of whether they have been backed up before or not. A full backup is typically the largest backup type since it includes all data.
2. ?Incremental backup: This type of backup only copies files that have changed since the last backup (incremental or full). Incremental backups are typically smaller in size since they only include new or changed data.
3. ?Differential backup: This type of backup copies all selected files that have changed since the last full backup. Differential backups are typically larger than incremental backups but smaller than full backups since they include new or changed data since the last full backup.

Ⅱ. Where to Backup Hard Drive? Follow Backup Rules

There are many different storage locations that you can use to backup your hard drive data. The most common storage locations include:

1. - Other local hard drives or a second internal hard drive on your computer
2. - External hard drive (e.g. USB hard drive, SD card, or a USB flash drive)
3. - Cloud storage (e.g., OneDrive, Dropbox, Google Drive, etc.)
4. - Network Attached Storage (NAS)
5. - Optical discs (CDs, DVDs, etc.)
6. - Tape drive

Among all the possible backup location choices, which one should you choose to keep the hard drive backup files? Experts in the backup industry recommend users follow a 3-2-1 backup rule.

The 3-2-1 backup rule is a simple but effective rule that states you should: 

1. - Keep at least three (3) copies of your data, 
2. - Store the backup data in two (2) different locations, and 
3. - Have at least one (1) backup copy offsite.

For example, you can backup important files to an external hard drive, clone the hard drive to a backup hard drive, and also upload critical data to a cloud backup service. By doing so, you are following the 3-2-1 backup rule and protecting your data in the event that one of the backup locations fails or is corrupted.

Ⅲ. What Should You Back Up on Your Computer Hard Drive?

When it comes to backup, some people only backup data files (e.g., photos, music, documents), while others backup everything including the operating system, applications, and settings. The general rule of thumb is to backup anything that you cannot afford to lose.

Here are some things you may want to consider backing up:

1. - Essential Data files: This includes photos, music, videos, documents, etc.
2. - Application settings: This includes preferences, customizations, and configurations.
3. - Operating system: This includes the Windows Registry and system files.
4. - Emails: This includes messages, contacts, and account settings.
5. - Databases: This includes financial records, customer information, inventory, etc.

Selecting the right backup contents makes the whole backup thing meaningful. Moreover, knowing when to backup also means a lot. Ideally, you should backup your hard drive data on a regular basis so that you always have a recent backup available in case of data loss. The frequency of your backups will depend on how often your data changes. For example, if you have a lot of files that are constantly changing (e.g., photos, videos, etc.), then you will want to backup your hard drive more frequently than someone who has mostly static files (e.g., documents, spreadsheets, etc.).

Ⅳ. How to Backup Hard Drive? 4 Ways Are Available

As we know, backup is always considered an effective way to protect data from any sudden unexpected disasters like hard drive failure, virus attack, system crash, human error, etc. Then, how to backup the hard drive? Is there anything you should pay attention to during the backup process? Read on and find the answers now.

Method 1. Copy Hard Drive Data (Small hard drive backup choice)

The first and most common way to backup data is to manually copy and paste important files from your computer hard drive to an external hard drive. This is a simple and straightforward process, but it has several disadvantages.

• First, it is time-consuming and requires you to select the files you want to backup manually.
• Second, it is easy to overlook important files and folders.
• Third, it is difficult to automate this process.
• Lastly, it does not backup system files or application settings.

Tip: The manual method to create hard drive backups is not limited to copy and paste. If you're advanced users who know Windows Command Prompt operation, you should know that the Xcopy and Robocopy are two of the most applied backup command tools that are used to backup files and directories from one hard drive to the other. 

If you want to create a real backup file of your hard drive, the following three ways provide you with more valid solutions. You can compare these methods and choose the one that suits you the best.

Method 4. Backup Failing Hard Drive

If your hard drive is failing, you should backup your data as soon as possible. A failing hard drive can fail completely at any time and you could lose all your data if you don't have a backup.

Below are some signs or signals that imply a dying hard drive:

• Your computer is taking longer to start up or load programs.
• Your hard drive is making strange clicking or grinding noises.
• You are seeing more error messages than usual.
• Your computer is crashing more often.

If you see any of these signs, you should backup your data immediately. The best way to backup a failing hard drive is to use the clone method.

The clone method copies all the data from one hard drive to another. This is the best way to backup a failing hard drive because it creates an exact copy of the original hard drive.

To clone a failing hard drive, you will need two hard drives: the original hard drive and a new hard drive. The new hard drive should be the same size or larger than the original hard drive. EaseUS Todo Backup Home, the upgraded version of the free version, can provide users with the best experience of cloning a failing hard drive for an emergency backup.

Step 1. On the main page, find and click "Tools". You can see clone and other utilities.

Step 2. Choose the source disk or partition, click "Next".

Step 3. Then you need to choose the target disk. Make sure the target disk is larger than the source disk or partition.

Step 4. A warning window will inform you that clone would permanently wipe out all data on the target disk/partition, if you want to start clone, click "Continue."
