get all folders of a disk with total size in MB or GB

Hi Forum,

I have a question about making a script. i have a script to list the folders in a folder wit size, name of the folder, created
it has been exported to html.

but this is a test because this sript must be changed to the following that it must do.

we have to backup server with x counts of disks
server a has 3 disks
server b has 2 disk

on both disks are serveral folder of customers that has their own backupfolder.

once every month there must be a xml, html, or what ever format to puth out a list of both servers with the disk of every folder, name / created / changed / size

servers are online accessable through IP, and adminstrator credentials must be built in the script but encrypted.

in the top there must be showned date and time when the output is created.

and if possible the output must also be automated send.

i will put the script in the next comment.

is there someone that can help me with this?
