mod_backup serves two different purposes: it makes a nightly backup of your files and database, and can also backup/restore individual resource items.

Daily backup of database and files

Losing data is bad for business. This applies to your customers as well if you are building sites for them. It is critical to keep backups of any Zotonic sites you develop.

After enabling mod_backup, it will make a backup of the site’s data every night at 3 AM. It keeps the last 10 copies of the data, so you have alway a backup to roll back to.

The backups are stored under backup in the files directory of your site. Check in the admin under System > Status to see where the site files directory is located.

The site’s media files are stored as a .tar.gz file, while the database is stored as an uncrompressed .sql file.

We advise to add a cron script to the server for copying the data to remote storage.

Per-resource backup/restore
