Do you want to know why the transaction log files are getting bigger? Transaction logs can sometimes be even larger than your actual database files, especially if you are applying a data warehouse. Why is this happening? How do I control its size? How does the database Recovery model control transaction log growth? In this series of articles, we will answer each of them.

The essential difference between crash/instance recovery and media recovery is: Crash/instance recovery applies the redo log from the incremental checkpoint (incremental checkpoint) for the instance that needs to be recovered. Because the first condition of log coverage is to complete the logfile switch checkpoint of the relevant log, and the archive log is alway

Category of Hard Disk faults Since the birth of computers, data recovery has gradually matured along with the development of computers. In today's information age, data recovery is even more important. Modern data recovery technology can solve data loss problems caused by multiple hard disk faults. To sum up, there are roughly three types of Hard Disk faults that
