Free Cloud storage provider with an API WITHOUT oauth? [closed]

Question

Anybody knows a FREE (some free volme, 2-5 GB i mean - continuously, not just the first year like Amazon S3) cloud storage provider which has an API that does NOT use oauth ?

I need that to make regular backups to from a console service (scheduled web-browser and user-input free application).

I have looked at DropBox, Google Drive, SkyDrive and UbuntuOne.
DropBox & Google use oAuth, which I can't use (oAuth is NOT web-browser & user input free).
UbuntuOne's "API" is a horrible mess - simply unusable.
SkyDrive SDK needs Windows. I have my data on a Linux server, and that's not gonna change.

You can access SkyDrive over WebDAV, would that work for you? – Partition

@Kevin: Hmm interesting. Yes, I think WebDAV is possible on Linux with C#/mono. – Henze

You don't even need your code to handle the WebDAV part. Just mount the WebDAV share and then your code can just pretend it's a local folder. – Partition

FREE for life without any benefits? Oh yes, I want free food, free medicines, free traveling. Come on, they are not charging millions, they are charging in cents. – Cutlery

Parse gives you 1GB storage for free. – Grubstake
