Using a USB external hard disk for backups with Linux

In this article, I show how I set up a recently purchased USB external hard disk drive as a backup drive for my Linux desktop PC. I’ll delete the default FAT32 partition, create a new partition, make a reiserfs filesystem, and show how to use rsync to backup your important data.

Why backup with Linux?

The question should really be “Why backup with Linux instead of Windows, if I have a dual boot PC?” Personally, I don’t dual boot, so for me the question never arises. However, I can think of a number of reasons why I would use Linux as my OS for running backups.

* Windows cannot read your Linux partitions without third-party addons.
* Conversely, Linux can (natively) read your FAT32 and NTFS partitions.
* It is straightforward to create a backup script which mounts those partitions, backs them up, then unmounts them.
* Backing up to Linux renders any virus-infected files inert.
* Would you leave a Windows PC running overnight, unattended?
