indexedDb backup in the cloud
===

I would like my client web app to be able to backup the indexedDb database.
I do not have a webserver

i found this: http://stackoverflow.com/questions/7798098/exporting-and-importing-indexeddb-data#answer-8205461 
that says: "you can call an export callback passing the privileged array of objects representing a backup of your object store" 
so i have an array of objects in javascript which is my backup... 
how can I :
1. turn it to a file?
2. back it up in the cloud?

thank you for your help.

nb: I would love to use dropbox api, i have found this http://code.google.com/p/dropbox-js/source/browse/#svn/trunk but doesn't know if it works ( will try it and let you know).

nb: Also i am planning to use pokki.com to deploy app on client's desktop.
