+Here we are describing a basic back-up scenario for our site. We will be using Amazon S3 for the backup.
+
+## Install *Backup and Migrate* Module
+
+Sign in as the *webadmin* user:
+
+```
+$ sudo su - webadmin
+```
+
+Download and enable the *Backup and Migrate' module:
+
+```
+$ cd cms
+$ ./vendor/bin/drush dl backup_migrate
+$ ./vendor/bin/drush en backup_migrate
+```
+
+## Setup CRON
+
+Run `crontab -e` as the *webadmin* user and add this cron job:
+
+```
+0 * * * * wget -O - -q -t 1 https://cms.theo-andreou.org/cron.php?cron_key=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX#overlay-context=
+```
+
+## Create a scheduled backup
+
+Go to `Configuration -> Backup and Migrate -> Schedules`:
+
+Press the 'Add Schedule':
+* Schedule Name: **Daily backup**
+* Backup Source: **Entire site**
+* Enabled: **Tick**
+
+Keep the default settings on everything else.
+
+## Prepare the backup script
+
+Install prerequisites:
+
+Prepare the following script (*/etc/cron.daily/backup-cms*):
+
+```
+#!/bin/sh
+
+PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
+
+CMS_BACKUP_PATH=/srv/webadmin/cms/sites/default/private/backup_migrate/scheduled
+S3_CMS_LOG_PATH=/var/log/aws-s3-sync-cms-$(date +%F).log
+S3_BUCKET=s3.example.com
+
+aws s3 sync ${CMS_BACKUP_PATH} s3://${S3_BUCKET}/ 2>&1 ${S3_CMS_LOG_PATH}
+
+find ${CMS_BACKUP_PATH} -type f -mtime +30 -delete
+find /var/log/aws-s3-sync-*.log -type f -mtime +30 -delete
+```
+
+Give execute permissions:
+
+```
+# chmod +x /etc/cron.daily/backup-cms
+```
+
+**NOTE: This is an over-simplified backup scenario. For large installations you may need to come up with something more elaborate.**
