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 enter the URL (starting with http://) to your perlQ backup file (normally 'backup_YYYY-MM-DD.perlQ' if you have downloaded all data) in the "Restore From URL" row. Then select your Restore Behavior and click the "Retrieve Database" button to have the specified backup restored into the database.

Note: Perl requires you to have installed the LWP (libwww-perl) module in order to retrieve items via a URL.

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 is stored on your hard drive, you may want to look into restoring from a data file.
