In your admin panel, click 'backup database' to reach your database backup and restore options. From this page you can download a current backup, upload an old one, or set an automated backup schedule. If you set an automated schedule, you must CHMOD 777 your admin directory. It will select a random file name and write to that file with the frequency you have told it to. You can stop it from continuing to write automatic backups by returning to the page and clicking the link that appears offering to stop backups.

You can restore a backup through WSN which was made in phpmyadmin, or restore a WSN-generated backup through phpmyadmin (UNLESS using 3.13 or earlier in which case you shouldn't restore a WSN one in phpmyadmin).

Please note that to restore a backup you must have entered the path to your attachments directory on your settings page and chmoded attachments to 777. This is neccesary since without this inconvinience it would not work with php in safe mode.

If you will be restoring a backup to a different directory than the original, be certain that your directory url field on your settings page is emptied. If you don't empty it, you'll end up being fowarded to the old location after restoring. You can also remove the directory url by searching for your url in the .sql file after downloading.

If backups don't work for you, this means PHP doesn't have permission to execute shell commands (probably it's in safe mode). If this is the case you'll have to use a tool such as phpmyadmin for backups.
