WP Backup Plugin

WP Backup Plugin Version 1.2 by Umar

Lately it has not been backing up to schedule. I had a problem and I clicked Restore to my latest backup of 19th October. The site has broken!

Will have to get help from someone as to what is best course of action. Do I delete the plugin first after downloading my backups to my computer?

Appreciate some guidance. All other plugin are up to date
