Follow along with the video below to see how to install our site as a web app on your home screen.
Note: This feature currently requires accessing the site using the built-in Safari browser.
this may be related to the control panel server OS upgrade, I am not 100% sure on this but I believe the backup feature runs off of a cronjob, and if it failed it won't run.
Now for an alternative, you can make a backup from phpMyAdmin or SQLyog and do a DB export. And for the web files you can use the webshell archive feature. This will do the same thing in a less manageable way, but it is a work around for the time being.
We have given the backups as per your request.
Deepak mentioned it is fixed. Can you check and confirm?
