Server Backup Script

This backup script creates an archive of incremental backups. Backup directories are named according to the current date, so the script is designed to be run on a daily basis.

The operation of the backup script is described here: http://dev-notes.eu/2015/06/incremental-backup-on-server/.

Usage Instructions

• Clone this repo to a suitable location, e.g. ~/sysadmin
• Copy the variables.sample file to variables
• Edit variables with server specific data
• The script requires a backup user for MySQL - for sample commands see backup-mysql-user
• Create a symlink to server-backup within your $PATH
• Make sure server-backup is executable

The script works on the basis that you have created a non-sudo user with the name ${SERVERNAME}backup, where ${SERVERNAME} is the name of your server.

If necessary, the setup script sets up all necessary directories.

Automated Setup

You can set up necessary backup and source directories by running ./setup in this directory. This script creates all necessary symlinks and directories for the incremental backup to work.

Setup Commands

Sample setup commands:

cd ~/sysadmin/server-backup

# Make the backup script (and setup script) executable
sudo chmod +x server-backup
sudo chmod +x setup

# Create a suitable symlink - to be run as root by a cronjob
sudo ln -s ~/sysadmin/server-backup/server-backup /usr/local/sbin/server-backup

# Run the setup script to set up necessary directory/symlink structure
sudo ./setup
