Should you save logs in database?
Storing your logs in a database isn’t a HORRIBLE idea, but storing them in the same database as your other production data is. Maybe you’re conservative with your logging and only emit one log line per web request normally.
What is the importance of maintaining clean log files that are well formatted?
Preventing errors from ever getting to a production site is often the most efficient and cost effective answer, but bugs happen. Keeping an eye on the logs for all your applications will help ensure your end user has a better experience, and your hardware/applications are performing their best.
How do you maintain database logs?
In order to maintain a history of changes to the database’s data we need to record every insert, update, and delete to some sort of “history” table. In addition to capturing the data that was inserted, updated, or deleted, we also need to note what user made the modification, as well as the date and time it was made.

Where should logs be stored?
Your log store should strategically located in direct sunlight (ideally south facing), allow good airflow, and where it can be easily accessed. In most cases, log stores are open at the front, have a slanted roof, and supplied with a raised floor.

How often should transaction logs be backed up?
Taking a log backup every 15 to 30 minutes might be enough. If your business requires that you minimize work-loss exposure, consider taking log backups more frequently. More frequent log backups have the added advantage of increasing the frequency of log truncation, resulting in smaller log files.
Where should we store logs?
Preferably, logs should be placed on wooden pallets as these keep them off the ground and provide a free flow of air underneath; the ideal height of the wood stack (including the pallet) should be no more than 3ft (1m) as the logs can become unstable if piled too high.
How to clean up database log file automatically?
The default is Full which means you’ll be doing backups of the database and transaction log. When you backup the transaction log, it will truncate. If you never backup the transaction log, it will grow forever. If you only want to backup the full database, then change the recovery model to simple.
Why is it important to have a clean log file?
Sometimes the root cause of the problem is an obscure scenario, or product bug not easily discernible from debugging or logs. But, on many occasions, the answer is right there in the log files.
Why is the database log file always full?
The log file is dependent on the database recovery model. The default is Full which means you’ll be doing backups of the database and transaction log. When you backup the transaction log, it will truncate. If you never backup the transaction log, it will grow forever.
What should I do with my SQL log file?
If you never backup the transaction log, it will grow forever. If you only want to backup the full database, then change the recovery model to simple. Once this is changed you’ll want to shrink the log files (right-click database in sql management studio, Tasks > Shrink > Files).
