Is it possible to restore deleted files?

Hi, I received a notice that my free OneDrive is almost full. So I deleted a lot of files from my OneDrive to find out they vanished from my computer as well. How is it possible? Isn't it supposed that the cloud saves copies of the data on my computer? I also cleared the OneDrive recycle bin. Is it any chance to restore my files? Can I do it if I get subscription, e.g. for one month? Thanks in advance for help.
