What is the method of clearing SQL Server logs?

There are several methods for clearing logs in SQL Server.

1. Backing up and restoring operations: Regularly backing up the database and log files can help clear the transaction logs. Once the backup is done, you can free up space by shrinking the database log files.
2. To shrink the size of a database log file, one can utilize the DBCC SHRINKFILE command. For example, the following command can be executed to shrink the log file size of a specific database.

USE [YourDatabaseName]
GO
DBCC SHRINKFILE (YourLogFileName, 1)
GO

1. Change the database recovery mode to simple mode to automatically clear the log files, but be aware that this may bring a risk of data loss.
2. Manually clean up log files: You can clean up logs by manually deleting old log files or log backup files. However, be cautious to avoid deleting important log files.

It is necessary to choose the appropriate cleaning method based on the specific situation, and regularly clean the database logs to prevent the log files from becoming too large and causing a decline in database performance.
