Why need to automatically backup files to external hard drive?

When was the last time you backed up the important files on your computer? Three months ago when your friend called in tears that she lost her thesis because of computer failure? Maybe it is longer. You know the importance of system backup, while file backup cannot be ignored, either, especially to backup those significant documents, office files, and irreplaceable photos.

Computer failure, hardware conflict, hard drive damage, or hacker invasion is a fact of computer life. It’s not a matter of whether or not your computer will encounter these problems, it’s a matter of when. As for the destination backup path, you can backup files to internal hard drive or external hard drive or the like for better protection. The latter way avoids the data loss caused by system disk failure or system meltdown.

Backup to External Hard Drive

You know the importance of backup, how about automatic backup? We all are busy with various stuff, work, family, friends, school, etc. It is hard to promise we can remember to do backup for each modification. But with the help of a schedule or auto task, it becomes a piece of cake. And it saves you much time and effort as well as protects your precious memory.

How to automatically backup folders/files to an external hard drive

Usually, Windows backup utility can do a regular backup, such as Backup and Restore, File History. Both of them allow you to automatically backup files to external hard drive. Also, there is much useful third-party software that can do this, AOMEI Backupper Standard, for example. Then, which one should you choose to schedule backup files? Please stay for a while, check the difference among them, and then make a decision.

  • Backup and Restore is able to backup files saved in libraries, on the desktop, and in default Windows folders. Also, you can choose whether or not to include a system image in the backup task. In addition, you can choose to backup specific files or partition on the disk. It supports daily/weekly/monthly schedule backup
  • File History is designed to backup files or folders in the user folder, so you can only add files or folders you want to backup to that folder ahead of time. In Windows 10, you are allowed to backup specific folders by directly adding folders. It supports backing up files from every 10 minutes to daily and saving multiple backup versions from 1 month to forever.
  • AOMEI Backupper is an all-in-one backup software to backup files, partition, system, disk, or create a cloud backup per your needs. You can backup any files you want, from a local disk, external disk, USB drive, network path, or cloud drive. It supports multiple schedule settings and other backup options, such as, daily, weekly, monthly, incremental backup, normal or high compression level, etc.

Now, you can choose one backup tool among them and start your new journey to automatic backup files.

Way 4: Automatically copy files to external hard drive in another manner with AOMEI Backupper

Backup means you create an image for certain files, and when you need them back, you should restore the image to files. Syncing files to external hard drive is to make an exact copy of these important files and you can use them directly without restoration.

Step 1. Launch AOMEI Backupper Standard, and go to Sync > Basic Sync this time.
