We are going to upgrade the SAS 9.4 M3 to SAS 9.4 M4. Any advice of suggestion during upgrades?
Is there any way we can backup whole sas env including sas installation files, sas data, sas config, metadata etc ?

the upgrade should be quite straight forward and a good backup upfront is always a good idea for possible rolling-back scenarios. You can always find additional details in the guides provided by SAS at http://support.sas.com/documentation/cdl/en/whatsdiff/66129/HTML/default/viewer.htm#titlepage.htm
About the backup itself, if you have got virtual machines, a full snapshot without memory state should work OK. If you don't, stop every SAS service and sas processes, including LASR or batch jobs, and (if you are on Linux servers as I believe to recall) copy the sashome (binaries) and config folder to another drive, keeping the permissions.

SAS Metadata Backup (SMC): backups metadata only.
BackupManager, the GUI for the SAS Deployment Backup and Restore Utility, will backup: SAS metadata, SAS Content Server, WIP (postgress) database, and the key configuration files of the Application servers, including SAS Meta.
This means the toll won;t backup, by default, SAS data or other important folders (as other SAS services, the LASR files, Autoload, Web Applications, SAS binaries, etc). You can include those folders, of course, but for those purposes I highly recommend you a generic Backup as you would do for other services. But you will need downtime on the SAS services, to not block any file during the backup process.
