Rsnapshot is an open-source local/remote filesystem backup utility written in Perl, which leverages the power of Rsync and SSH to create scheduled incremental backups of Linux/Unix filesystems.
Rsnapshot only takes up the space of a single full backup plus the differences, allowing you to store backups on a local drive, external USB stick, NFS-mounted drive, or over the network to another machine via SSH.
In this article, we’ll walk you through the process of installing, setting up, and using Rsnapshot to create hourly, daily, weekly, and monthly local backups, as well as remote backups.
