Backup the Database

The purpose of this script is to backup and optionally --sanitize the database of your Backdrop CMS website.

Requirements

  • Linux server
  • Backdrop CMS website
  • PHP CLI

Installation and Configuration

Clone this directory down to your filesystem. Perhaps to your home directory.

Copy the config.ini.example file to config.ini

  • cp config.ini.exaple config.ini

  • Set the config variables in config.ini to values appropriate for your server and Backdrop database.

  • Required configuration variables. Copy the config.ini.example file to config.ini and replace with values for your server.

; This user must have access to create and drop databases to use `--sanitize`
DB_USER = root
; Password of the above user
DB_PASSWORD = pass
; Database to perform backups and optional `--sanitize`
DB_NAME = backdrop
; Host of the Database usually localhost, but could be an external name or IP
DB_HOST = localhost
; Root directory of the Backdrop installation
BACKDROP_ROOT = /var/www/html
; Directory where you would like the backups to be stored
BACKUP_DESTINATION = /home/user/me/backups

Usage

One time use Database Backups

  • php path/to/sql-dump-sanitize.php
    • This will create a backup of the database written to the BACKUP_DESTINATION specified in config.ini.
  • Options
    • --quiet (-q alias) suppress standard output (good for running as cron job)
    • --sanitize (-s alias) sanitize user email addresses for the backup. Sanitized backups are placed in BACKUP_DESTINATION/sanitized subdirectory.
    • --rollover (-r alias) remove stale backups where stale is defined by the NUM_KEEP config variable.

One time use files directory Backups

  • php path/to/files-backup.php
    • This will create a backup of the files directory written to the BACKKUP_DESTINATION/files_backups specified in config.ini
  • Options
    • --rollover_files (rf alias) remove stale files dierectory backups where stale is defined by the NUM_KEEP config variable.

To run periodically on cron.

  • Set a server cron task to run the script on a schedule (daily, weekly, monthly or any and/or combination). For example a weekly on 8.05am Saturday morning; the cron job would look like this:
# 1. Entry: Minute when the process will be started [0-60]
# 2. Entry: Hour when the process will be started [0-23]
# 3. Entry: Day of the month when the process will be started [1-28/29/30/31]
# 4. Entry: Month of the year when the process will be started [1-12]
# 5. Entry: Weekday when the process will be started [0-6] [0 is Sunday]
