Restore from a backup file created with the new_backup function.

Before using this function the following list of requirements must be must be fulfilled:

  • The user performing the restore must have FULL privileges on the@thingsdb scope.
  • No collections may exists. Use collections_info() and del_collection(..) to remove existing collections.
  • All nodes must be online and ready. If this is not the case, then either remove the node or wait for the node to become ready. Use nodes_info() to check for the status of the nodes.
  • When having multiple nodes, all committed events must be stored as well. Function nodes_info() shows both the committed_event_id and stored_event_id for all nodes. This is not a requirement when using a single node.

After running this function, all existing users and tokens will be overwritten, including the user performing the restore unless the take_access argument will be set to true. In both cases it is required to re-authenticate to ThingsDB after the restore is completed.

This function generates an event.
