Need to change the location of my Lightroom backup

[furf]

Hey folks,

My lightroom catalog crashed this morning and after several hours I was able to get it back.  Now I have a question of how can I change where my catalog is backed up (currently backing up on Microsoft OneDrive) but would like to change it to a external hard drive.  I am using a laptop with Win10 installed on it.

First, go to Edit > Catalog settings, and set  Backup Catalog to "When Lightroom next exits". (you can change it later)

Then close Lightroom, and click the "Choose ..." button in the backup dialog, and select a new location for backups.
