Why is my Backup dialog box not showing when I exit Lightroom Classic?

[LosFelizGirl]

Hey guys, I would like to redirect my backup folder to an external drive. However, the backup dialog box no longer pops up when I exit.  How do I get the dialog box to appear again? 

Thanks!

In LrC, bring up the Catalog Settings, look at the General Tab, look at the Backup section.

Thanks for the reply.  How do I bring up the Catalog Settings? I'm on a Mac if that makes a difference.

See "Customize catalog settings" in:

Catalog Settings is directly under Preferences in the 'Lightroom Classic' menu on your Mac.
