Freepbx-13: backup runs forever, never completes

I’m running freepbx-13 from the distro and when I try to do a backup it just runs all the time and never completes. I’ve tried this with a backup of my own and also running the default backup already there. It doesn’t give any error, it just sits there forever with the little blue line going left and right. I’ve tried seeing if there’s an backup module update but there isn’t one. Thanks for any advice.
