How to backup my external hard drive​？

Backing up an external hard drive is a crucial task to safeguard your valuable data. 

I. Importance of Backup

Data loss can occur due to various reasons such as hardware failure, accidental deletion, virus attacks, or natural disasters. An external hard drive is often used to store important files like photos, videos, documents, and backups provide a safety net.

By having a backup, you can quickly restore your data and resume your work or access your personal files without significant disruptions.

II. Different Backup Methods

Manual Copying

This is the simplest method. You can connect your external hard drive to your computer and then copy and paste the files you want to back up to another storage device, such as another external hard drive or an internal hard drive with sufficient space.

For example, on a Windows computer, you can open File Explorer, locate the external hard drive in the list of drives, select the files and folders you want to copy, right – click, and choose “Copy.” Then navigate to the destination drive, right – click in an empty space, and choose “Paste.”

However, this method can be time – consuming and error – prone, especially if you have a large number of files and need to do it regularly.

Using Backup Software

Windows Backup and Restore (Windows 7 and later versions have similar features)

In Windows, you can use the built – in Backup and Restore (Windows 7) tool. To access it, type “backup” in the search box on the Start menu and select “Backup and Restore (Windows 7).”

You can choose to back up the entire external hard drive or specific files and folders. You’ll need to select a destination for the backup, which can be another external hard drive, a network location, or a set of DVDs (if you have a DVD burner).

The software allows you to schedule regular backups, so you don’t have to remember to do it manually. For example, you can set it to back up once a week or once a month, depending on how often your data changes.

Time Machine (for Mac)

Mac users have the Time Machine utility. Connect your external hard drive to your Mac, and then open System Preferences. Click on “Time Machine.”

Select the external hard drive as the backup destination. Time Machine will then start backing up your Mac’s data, including any external drives that are connected and selected for backup.

It creates incremental backups, meaning it only backs up the changes made since the last backup. This saves space and time. For example, if you only modified a few photos on your external hard drive, Time Machine will only back up those new or changed photos.

Cloud Backup

There are many cloud storage services available, such as Google Drive, Dropbox, and OneDrive. Some of these services offer a limited amount of free storage space (usually a few gigabytes), and you can purchase more if needed.

To back up your external hard drive to the cloud, you first need to install the cloud storage client software on your computer. Then, you can select the files and folders on the external hard drive that you want to upload to the cloud.

However, uploading large amounts of data can be slow, depending on your internet connection speed. Also, you need to consider the security and privacy of your data when using cloud services. Some cloud services encrypt your data during transmission and storage to protect it.

III. Pre – Backup Considerations

Data Organization

Before you start the backup process, it’s a good idea to organize your data on the external hard drive. This can make it easier to select the files and folders you want to back up and also ensure that you don’t miss any important data.

You can create folders with clear names, such as “Work Documents,” “Personal Photos,” and “Videos.” Sort your files into these folders based on their types or usage.

Storage Space

Make sure you have enough storage space on the backup device. If you’re using another external hard drive for backup, check its capacity and available space. If you’re using cloud backup, calculate the amount of data you need to back up and ensure that you have enough cloud storage space either through free quotas or purchased plans.

Backup Schedule

Decide on a backup schedule that suits your needs. If you add or modify data on your external hard drive frequently, you may want to back up more often, such as daily or weekly. If the data is relatively static, a monthly backup may be sufficient.

IV. Performing the Backup

Full Backup vs. Incremental Backup

A full backup copies all the data on the external hard drive. This is useful when you’re doing the first backup or if you want a complete snapshot of your data at a particular time.

An incremental backup, on the other hand, only backs up the changes made since the last backup. It’s more efficient in terms of storage space and time, especially if you have a large amount of data. Many backup software programs support both types of backups.

For example, if you have a 1 – TB external hard drive and you do a full backup, it will copy all 1 TB of data. But if you do an incremental backup after adding a few gigabytes of new files, it will only copy those new files, saving a lot of time and storage space.

Verifying the Backup

After the backup is complete, it’s important to verify that the data has been backed up correctly. Some backup software has a verification feature that checks the integrity of the backed – up files.

You can also manually check a sample of the backed – up files. For example, if you backed up a set of photos, try opening a few of them from the backup location to make sure they are not corrupted.

V. Maintaining and Updating the Backup

Regularly Update the Backup

As you add, modify, or delete files on your external hard drive, you need to update the backup to reflect these changes. If you’re using backup software with a schedule, it should take care of this automatically. But if you’re doing manual backups, you need to remember to update it regularly.

Backup Storage Device Maintenance

If you’re using an external hard drive as a backup device, you should take care of it just like any other hard drive. Keep it in a cool, dry place to prevent overheating and damage.

Also, periodically check the health of the backup device. Some external hard drives come with diagnostic software that can check for errors and bad sectors. If you notice any problems with the backup device, you may need to replace it and redo the backup.

Backing up your external hard drive is an essential part of data management. By choosing the right backup method, considering pre – backup factors, performing the backup carefully, and maintaining the backup over time, you can ensure the safety and availability of your valuable data. Regular backups can save you from the headache and potential losses associated with data loss events.
