Nowadays, online backup is very popular. I redeemed a portable hard disk last month and notice that, the company provides one year of free online backup with unlimited storage. However, I never proceed to backup my stuffs online. I am wondering, if I backup my stuffs online, after the one year period, if I no longer want to continue the service, will my documents and other stuff that I backup online will be deleted? If not, can the company promise our files will not expose to another party? I have no idea. That is why, I am still using a portable hard disk to backup my own documents and files.
