Moving/ copying workbook to server location

Quick question here,
Can I use VBA to move a worksheet to a webserver location?
My idea is kind of raw here, but the point was to use vba to move the workbook that is on a client to a diskspace on a remote server .
That way my server would receive the clients workbooks as backup/ protection from my work.
Don't know if there is something similar or tried in that matter.
Also have some doubts about security, on the server side (the client could find the method and access all workbooks from his and other clients), as well as the client side.
Some, help/ guidance on the way to follow would be appreciated.

So any thoughts?
