The log files in SQL Server mainly consist of transaction log files and error log files. There are several methods to clean up log files, which include the following:<\/p>\n

    \n
  1. Cleaning up transaction log files: Transaction log files can be cleaned up by backing up the log files or shrinking the log files. Here is how you can do it specifically:<\/li>\n<\/ol>\n
      \n
    1. Backup log files: Use SQL Server Management Studio (SSMS) or Transact-SQL command BACKUP LOG to backup transaction log files, and after the backup is completed, you can clean up the log files.<\/li>\n
    2. Reduce the log file size: Use SSMS or Transact-SQL command DBCC SHRINKFILE to shrink the transaction log file in order to clean up the log file.<\/li>\n<\/ol>\n
        \n
      1. Clean up error log files: Error log files record error messages generated during the operation of SQL Server, and can be cleaned up using the following methods:<\/li>\n<\/ol>\n
          \n
        1. In SSMS, right-click on the SQL Server instance, select properties, and then in the “Error Logs” tab, set the maximum number and maximum size of the error log files. When the number or size exceeds the set limit, old error log files will automatically be cleared.<\/li>\n
        2. Manually clean up error log files and create a new error log file by using the Transact-SQL command EXEC sp_cycle_errorlog.<\/li>\n<\/ol>\n

          It is important to note that before cleaning up log files, make sure to backup the database to prevent data loss. Additionally, cleaning log files may affect the performance of the database, so it is recommended to do this during off-peak hours.<\/p>\n","protected":false},"excerpt":{"rendered":"
