backup

Script for creating filesystem snapshots.

Introduction

This script creates snapshots of the desired directories. When it is run, it mirrors the most recent backup and syncs any changes made since then. This allows you to see the system as it was in that moment of time. To minimize space used, the script mirrors with hard links.

By default, the script backs up these root directories: /boot /etc /home /opt /root /usr

Note: To back up directories that the user does not have permission to or to back up to a directory where the user is not allowed to write, the script needs to be run with superuser permissions.
