CWP Config Files Backup

Set up hard links and mounted folders in order to make remote backups of the system configuration.

Make directories

$ mkdir /backup/config
$ mkdir /backup/config/etc
$ mkdir /backup/config/etc/my.cnf.d
$ mkdir /backup/config/etc/postfix
$ mkdir /backup/config/opt
$ mkdir /backup/config/opt/alt
$ mkdir /backup/config/usr
$ mkdir /backup/config/usr/local
$ mkdir /backup/config/usr/local/apache
$ mkdir /backup/config/usr/local/php

Hard link files:

$ cd /backup/config
$ ln /etc/fstab
$ ln /etc/my.cnf
$ ln /etc/postfix/main.cf

Mount folders

Symlinked folders will not sync to Amazon S3, so we mount them using fstab.

Set up fstab to auto mount folders on boot:

$ nano /etc/fstab

Paste the following at the end of the file:

# Mount file paths for backing up config
/etc/my.cnf.d   /backup/config/etc/my.cnf.d     none    ro,defaults,bind        0 0
/opt/alt /backup/config/opt/alt none	ro,defaults,bind        0 0
/usr/local/apache /backup/config/usr/local/apache       none    ro,defaults,bind        0 0
/usr/local/php /backup/config/usr/local/php     none    ro,defaults,bind        0 0

Test fstab mappings:

$ mount -a
