How to backup to server from 9 machines on the network?

[GeorgeilotS]

Hello,
I have a question.
This network has Windows 2008 Server with Acronis Back for Windows Server. Along with 9 Windows 7 Professional machines on the domain that access the active server directory and the mainframe files that all 9 access and work on excel files.
My question is this.
Is there some way I can select to backup the PST Outlook 2013 file or folder containing it and My Documents folder from each of the 9 machines? Is it possible to do it incrementally after the initial backup is done?
Or Is there a way to say, set the Outlook folder that contains the pst file as a shared folder on the network, then somehow have that backup to a folder on the server each night?

Are you using folder redirect to save their documents on the server or are they all on the local clients?
