How long for a full backup?

[CSS]

I just initiated a full backup from my cpanel. It said that it will email me when its done. When should I expect it to do so?
The site is about 45MB + 15MB SQL.

Well, I'd think it wouldn't take all that long; of course,
I could be mistaken since I never use cPanel's backup tools.

Now the link of the backup appears in my cpanel, but no email yet.

Did you set your contact email address in cPanel for it to use?
