Backup not downloading

Hello! My site has been hacked and I wanted to restore it from a backup i created on february the 3rd, but everytime I hit the “download backup” button, a window pops up saying “the download will begin shortly” and it disappears after a couple of seconds. I’ve tried multiple browsers and nothing happens. The backup size should be just under 1 GB, but if I navigate to the floder via the hosting file manager I only see 5kb files in the backup folder. Can you please help? Thanks!
