I encountered the error below.
Msg 9002, Level 17, State 2, Line 1
The transaction log for database ‘DBName’ is full due to ‘LOG_BACKUP’.
The following are the corrective actions that can be done.
- Take a log backup (The #1 cause of full transaction log is the lack of backups)
- Kill a long-running transaction
- Alter database mirroring, availability groups, or replication to allow the transaction log to clear
- Either manually grow the existing log file(s) or add another log file (temporarily)
- As a last resort, switch to SIMPLE recovery model
Execute the script below to know what is the reason why the log cannot be cleared.
SELECT [log_reuse_wait_desc] FROM [master].[sys].[databases] WHERE [name] = N'DB_Name'; GO
Some examples of why the log is not clearing are LOG_BACKUP, DATABASE_MIRRORING, NOTHING.
