Solution:

By seeing above this line: \\SCCMBackup\CD.Latest failed. Error = [error code: 5, error message: Access is denied. Backup failed with access deny.

After doing lot of research McAfee was blocking the CD.Latest file as it contained the autorun.in which by default is blocked by McAfee software as a default rule. It had to be excluded. Once done, backup worked successfully.

Happy Learning!!!!
