Back up sdcard to cloud Problem: I have an internal flash drive (/sdcard) with "stuff I don't like losing". Due to a bug in ClockworkMod Recovery, it got wiped the other day. I had been manually backing up my entire card to my local computer every so often, but it was a manual process.

I have a Box.com account. I have a Dropbox account. I have a Google Drive account. I want to automate uploading everything to one of those services (preferably Box, as I got in on the 50GB promo they did). I'm assuming this exists as a free or one-time purchase app, but all I can find are "back up services" that require a subscription.  I use Titanium Backup to back up my apps, I take full images of my phone via CWM every so often, but I can't pass all that data to the cloud (well, TiBu will upload to Box/Dropbox, but that's not everything).

Dropbox has a built-in image backup that will automatically upload any pictures I take to my account. Google+ can do the same to my G+ account. However, that's still only a portion of what exists on my internal storage.  I want something that will grab everything else. Ideas?
If your device is rooted, you might want to take a look at Titanium Backup, which has built-in support for Dropbox, Box and Google drive.

As for your "special folder", I'd say you will probably like FTPSyncX -- which allows you automatically sync with Dropbox as well as with your local PC via SSH, FTP, and others. The latter can happen automatically all xx Minutes when your Wifi is in reach, or when any Wifi is in reach, or generally... And the App is well supported. Alternatively, there is FolderSync, additionally offering support for SkyDrive, SugarSync, Ubuntu One, Box.net, LiveDrive, Google Drive, Google Docs, HiDrive, NetDocuments, Amazon S3 and WebDAV.
