Michal Mocny commented on CB-1561:
----------------------------------

Samuel, This bug is specifically filed requesting to NOT backup localstorage/websql files
to iCloud (or rather the local backups).

== As an aside ==

There *is* a new ios6 feature to request localstorage backup to iCloud, which was "incorrectly"
enabled in cordova 2.1, which I've changed back to disabled for 2.2.
If some app developers like you really do want to backup to iCloud, then I can add a setting
for it, but to be clear that would only work for ios6 anyway.

More importantly, I am not sure that syncing these files will release achieve what you expect.
 We had a discussion on the cordova mailing list if it made sense to backup these files to
iCloud, and the answer was no -- but there was not really much debate or data here, and perhaps
we should revisit the issue.  What are your specific reasons for wanting this, so that we
can consider them?

> our App uses the Sotrage-API to store data which is being loaded upon first launch. 
> The app is rejected given the following reasoning:
> 'Your app does not follow the iOS Data Storage Guidelines, as required by the App Store
Review Guidelines.
> Please be sure to set the "Do not back up" attribute for all data which is not generated
or modified by the user. To check how much data your app is storing:
> - Install and launch your app
> - Go to Settings > iCloud > Storage and Backup > Manage Storage
> - If necessary, select "Show all apps"
> - Check your app's storage
> The iOS Data Storage Guidelines indicate that only content that the user creates using
your app, (documents, new files, edits, etc.) may be stored in the /Documents directory -
and backed up to iCloud.
> Temporary files used by your app should only be stored in the /tmp directory. Please
remember to delete the files stored in this location when the user exits the app.
> Data that can be recreated but must persist for proper functioning of your app or because
customers expect it to be available for offline use should be appended with the "do not back
up" attribute. For NSURL objects, add the NSURLIsExcludedFromBackupKey attribute to prevent
the corresponding file from being backed up. For CFURLRef objects, use the corresponding kCFURLIsExcludedFromBackupKey
attribute.
> For more information, please see Technical Q&A 1719: How do I prevent files from
being backed up to iCloud and iTunes?.
> Please revise your app so that it adheres to the iOS Data Storage Guidelines.'
> Is there a possibility to set this flag for the WebSQL Database file(s)?
> At least for us this is a blocker ...
