Backup Data
 | Backup Warning
Your data is priceless. Perform regular data backups and always keep a current copy (in a location other than on the machine on which you run CiviCRM) to guard against data disasters.

Database Backup
Your CiviCRM data is primarily stored in the MySQL database you've configured for your site. Before putting a CiviCRM site into production you should ensure that you have an automated procedure in place for generating a regular backup.

If you use a hosting provider, they may be able to offer regular backups as part of your service. It is advisable to inquire as to the disaster contingency plans in place (redundancy, offsite / multiple location storage of backups, etc.).
If you are setting up the backups yourself, there are a number of tool such as mysqldump or phpMyAdmin which can be used. Searching on "mysql backup" will give you options and links to procedures.
File-system Backup
In order to restore a complete copy of your site, you may also need to do regular backups of certain directories from your server's file system. These special directories are all configured under Administer CiviCRM » Global Settings » Directories.
- If you use custom fields to attach files to your contacts (e.g. photos or other images, resumes or other documents, etc.) - then you need regular backups of the Custom Files Directory.
- If you have configured Premiums with images - then you need to back up the Images Directory.
- If you have created custom template(s) to replace standard CiviCRM screen(s) - then you need to backup the Custom Templates Directory.
- If you have modified core files in the CiviCRM codebase - then you should also have a backup of those files.
