How do I stop a transaction log from filling up?

To keep the log from filling up again, schedule log backups frequently. When the recovery mode for a database is set to Full, then a transaction log backup job must be created in addition to backing up the database itself. Tips: 1.

Why is my log file so big?

Large database transactions, such as importing large amounts of data, can lead to a large transaction log file. Transaction log backups not happening fast enough causes the SQL log file to become huge. SQL log files also enlarge due to incomplete replication or availability group synchronization.

What causes SQL log file to grow?

Long Running Backup

If this backup operation keeps running for a long time, the SQL Transaction Log truncation will be delayed for a longer time and the SQL Transaction Log file will grow, due to not being able to reuse the inactive part of the log.

Why does transaction log get full?

When the transaction log becomes full, SQL Server Database Engine issues a 9002 error. The log can fill when the database is online, or in recovery. If the log fills while the database is online, the database remains online but can only be read, not updated.

How do I reduce the initial size of log file?

The first is to do a backup of the transaction log which will mark all of the items that get backed up as reusable. After that you can run the shrink command. The second is to change the recovery mode to SIMPLE then execute the shrink command and once that is finished change the recovery mode back to FULL.

Is it safe to shrink SQL log file?

Yes, it's fine. It doesn't affect any existing transactions, nor does it move any data around like database shrinking.

Can I shrink log shipped database log file?

No, shrink won't break Your log shipping configuration. But You must be aware that both shrink (and rebuild/reorganize You will have to do afterwards) will make Your transaction log files grow a lot.

How do I clear the SQL Server error log?

In SQL Server Management Studio, open the MANAGEMENT folder, then right click on SQL SERVER LOGS and say CONFIGURE. Check the LIMIT ERROR LOGS box and set the number to 30 (a month's worth). Now, set up a new job in the SQL Agent that runs sp_cycle_errorlog every night at midnight.
