"Meta Data" is all the data of a survey that is not response data. Every night, a back up copy of all meta data is saved to an external media and stored in a safe. The data is archived in a safe place, and may be restored should a system crash occur.
For server installations, your company must set up its own routines for backup.

SaaS only:
The MS SQL server periodically runs full backup of all response data in the database. In most cases it is possible to restore most of the data from a recent backup. In the case of a system failure, external media backups of response data also exist.
It is possible to delete response data from the web application. You are always asked twice before doing this (“Are you 100% sure?”), but it has happened that an Authoring user has accidentally deleted a running survey’s response data. It is the responsibility of the Authoring user to make sure that this does not happen.
