There are two things you need to do for massive deployment: install Beyond Sync itself on computers and setup tasks on these computers.
1) Install Beyond Sync
The setup file supports command line parameter "/VERYSLIENT". This parameter will install Beyond Sync without asking any questions. So you can use your management tool to install Beyond Sync easily via following command line "beyondsync-setup.exe /VERYSLIENT"
2) Setup tasks
The easiest method is to install Beyond Sync on one computer, setup the tasks you wanted. Then, deploy the whole configuration directory "%ALLUSERSPROFILE%\Beyond Sync" to the same location on other computers.
