I was looking for a free online cloud storage service which has a client for Linux and found this. Right now you get 1TB free online storage when you sign up.
They have a very comprehensive list of clients (in both English and Chinese) — probably the best I've ever seen, so I decide to share with you guys. It may be particularly useful if you use Linux regularly and only have limited free storage with Dropbox.
The website, yunio.com, seems like a Chinese startup company. The server is likely located in China which can potentially be a deal breaker. Anyway if you want some larger space for less sensitive files then this one may be for you.
Visit https://www.yunio.com/download to download the client. There are some Chinese characters but it's easy to figure out what it means. When prompted for installation make sure you choose English. Using the client is not as straightforward as Dropbox, as you need to manually create folders and upload files. You can also choose existing folders to sync and share. Haven't really tested thoroughly but I'd reckon it should be easy enough.
