How to create a secure incremental offsite backup in Linux with Duplicity
If you maintain mission-critical data on your server, you probably want to back them up on a remote site for disaster recovery. For any type of offsite backup, you need to consider encryption in order to avoid any unauthorized access to the backup. In addition, it is important to use incremental backup, as opposed to full backup, to save time, disk storage and bandwidth costs incurred in ongoing backup activities.
Duplicity is an encrypted incremental backup tool in Linux. Duplicity uses librsync to generate bandwidth/space-efficient incremental archives. It also uses GnuPG to encrypt and/or sign backup archives to prevent unauthorized data access and tampering.
In this tutorial, I will describe how to create a secure incremental offsite backup in Linux with Duplicity.
