When a system fails, it can be used to recover data to resolve database failures as long as there is a data log. As a SQL Server database administrator, it is important to understand the role of data log files and how to use them to troubleshoot common failures in some databases. Since the transaction

If you adjust the Restoration Model to a simple one, it does not support time point restoration, but the log file will be small.

It regularly checks the data cache, writes unused dirty pages to the disk according to the LRU algorithm, and clears dirty pages to release memory space. The Eager writer exists for batch inserts such as BCP. This process writes dirty data pages associated with non-log operations (such as large-capacity insertion and selection of insertion. This process allo
