Why Backup Files to External Hard Drive?

To start with backup to external hard drive, we must first learn what external hard drive is. External hard drive refers to a storage facility which has been considered as the fastest and easiest way to back up large amounts of data. Normally, external drive is connected to the computer via USB ports.

Backing up files to external hard drive, instead of internal disk, has these advantages: 

  • Save disk space: sometimes backup images could be of large size, which may occupy a lot of disk storage. Backing up to external or cloud perfectly solves this trouble.

  • Protect backed up data: these backup images would not be affected by operating system issues, internal hard drive errors, or human errors. And when a disaster occurs, one can easily restore system or important files. 

Backup to external hard drive means backup your computer system, hard drive, partition or files into an external drive. The best backup software AOMEI Backupper provides all the backup options you need: System Backup, Disk Backup, Partition/Volume Backup and File Backup.
