Suppress Backup information in Errorlog

After a long gap Im writing a article. This article is all about suppressing successful backup information into errorlog. Let me explain my scenario, In my working environment we have a production SQL Server with 60+ databases, all the databases are set to full recovery and data loss is accepted only for 15 min. Yeah you got me, we are taking Full backup daily, differential every 4 hours and transaction log backup every 15 min, there is no problem with the backup. We have one thing that is messing our error log, whenever a backup is taken by default SQL Server will write the detail to the errorlog as shown below.
