Ability to delete old "Full Account" backup files from within cpanel

As a System Administrator, I would like the “full backup” service to exclude the tar.gz file of the previous backup, so that each backup is not exponentially larger because it contains old backups.

I would also like the ability for user easily see the current backup files, their size, and ability to easily delete a file. (Perhaps a delete button next to each file in the listing.)

======================

When a customer creates a "Full Backup" in their cPanel, the backup file gets created in their account root. For example:

/home/username/backup-5.1.2019_10-37-55_username.tar.gz

Each time the customer presses the "Full backup" button, the prior backup files are included in the new backup file. So we end up with a situation where backup files are being backed up, and this exponentially increases disk space usage.

For example, let's say an account has 1gb in file usage. They click the "Full Account" backup button, and it creates a backup file of about 500mb. This file is then included in the next backup...

The 1st backup file is 500mb.

The 2nd backup file is 1gb.

The 3rd backup file is 2.5gb.

The 4th backup file is 5.5gb.

I hope that makes sense?

I realize cPanel already lists the available full account backup files in the Account Backups dropdown box, but it would be nice if there was an ability for customer to see the SIZE of these backup files, and also the ability to delete them.

We have many customers who run out of disk space because they are doing backups of their already existing backups...
