Backup Option In Master Reseller

I have bought a Master Reseller recently.

I have some technical question in my mind regarding backup.

I will start step by step.

1) I login to the WHM.

2) I click to WHMreseller Master Resellers placed on the bottom of the left menu.

3) There I saw some options at the bottom , 'Migrate' , 'Backup' ,'Change Owner', 'IP Delegation'

4) I clicked on 'Backup'.

5) There I saw two check boxes:

Enable Weekly Automated FTP Backups

Enable Weekly Automated Local Backups (will only run if cpbackups are disabled by root)


My questions are very simple:

Q1) What these two check boxes mean ?

Q2) If i check 'Enable Weekly Automated FTP Backups' and save these settings then every week , back of my all cpanels including cpanels of reseller will be generated or wht?
