You can recycle the SQLServer error log to decrease the ERRORLOG size using below link, but it will not solve your problem completely.

It is really difficult to read the ERRORLOG due to this backup information, and we can stop logging successful backup information by using one of the below solution
1. DBCC TRACEON
Run below command to turn off/stop the successful backup entries.
DBCC TRACEON (3226,-1)
If you restart the SQL Server the changes will be gone. If you want to make these changes permanent then you need to specify the flag at start-up parameter.
2. SQL Server startup parameters
You can add trace flag “-T3226” to SQLServer startup parameters to suppress successful backup information
- SQL Server Configuration Manager, Select SQL Server Services
- Right click on SQL Server Instance service go to properties and select "startup parameters" tab
- Enter “-T3226” value in “Specify a startup parameter” and click Add
- Click on Apply.
You need to restart SQL Server in order to affect the changes.
