perlQuestionnaire allows you to backup and restore your perlQ database. This is very useful in case you ever run into a corrupted database or your hard drive crashes. After you have backed up your database, you can be re-installed and running in minutes, without having lost any of your data prior to your last backup. Simply click the "Browse..." button in the "Restore Data File" row and find your perlQ backup ('backup_YYYY-MM-DD.perlQ' if you have downloaded all data). Then select your Restore Behavior and click the "Restore Database" button to have your backup restored into the database.

perlQ allows you to restore the entire database or a single survey and all results from one file. perlQ will automatically determine the format of the file and act appropriately. If your file exceeds the maximum file upload size or file uploads are failing for some other reason, you may want to look into restoring from a URL.
