InfoPath Dev

I've deployed an infopath form to a Windows SharePoint Services.
And my form has a "File Attachment" control on it.

What makes me wonder is that where do all the attachments got saved in the sharepoint library?
Clearly it's not saving the attachments on the local machine nor the network drive etc.

Anyone with a clue on this?
It may sound trivial, but it's kinda important to me as I'm planning to backup all the attachments submitted by the users.


Thanks!

File attachments will be there in the main DOM(thisXDocument.DOM), means this will be part of form XML.

FYI
File attachments are stored in base64 format in the XML.
