Retrieve missing submission?

I have a submission I know was there, and I go to print today and it's gone. I didn't intentionally delete, but could have on accident. Where could this submission be and anyway to retrieve deleted?

Hi,

Unfortunately, when you delete a submission, it will not be recovered anymore. This is because we let our users to have full ownership of their data, we do not do backups when the user deletes a submission. If it's deleted, it will be deleted in our servers permanently.

However, if you have setup email notification, you can use that as a reference for the missing submission instead.

I would also like to suggest that you integrate any one of our file sharing and storage services that we support (Dropbox, Google Drive, Box.net) to your form/s, this will let you have copies or backups uploaded directly to them in real time.

Thank you.
