How to take backup of all files and folders

[abdulcader]

Hi,

Actually im new to php programming. My client is having about 5 sites and he likes to take backup of all files and folders (not sql data) of all his sites. With out using FTP or any other .exe programs. But he likes to take back up of all sites from one master admin site.

For eg, he likes to take backup of www.site1.com, www.site2.com, www.site3.com, www.site4.com from the master admin site www.masteradmin .com. Using php script (web applications).

Can any one help me how to solve this

Thanks and regards,
