This log backup contains bulk-logged changes. RESTORE LOG AdventureWorks FROM DISK = 'C:\AdventureWorks.TRN'īut if there are bulk operations we will get this error. RESTORE DATABASE AdventureWorks FROM DISK = 'C:\AdventureWorks.BAK' This will restore the AdventureWorks database to at point in time equal to "Maat 5:31PM". But if you have another transaction log backup that occurred later and this does not have a minimally logged operation you can still use this transaction log to do a point in time recovery, but the point in time you are referencing has to occur within this second transaction log backup. One thing to note is that if your database is using the Bulk-Logged recovery model and there is a minimally logged operation (such as a bulk insert) in the transaction log you can not do a point in time recovery using that transaction log. When you restore your transaction log, SQL Server will replay all transactions that are in the transaction log and roll forward or roll back transactions that it needs to prior to putting the database in a useable state.Įach of these transactions has a LSN (logical sequence number) along with a timestamp, so when restoring the transaction log you have the ability to tell SQL Server where to stop reading transactions that need to be restored. When data is written to your database it is first written to the transaction log and then to the data file after the transaction is complete.

In order for this option to work, the database needs to be either in the FULL or Bulk-Logged recovery model and you need to be doing transaction log backups. This gives you the ability to restore a database prior to an event that occurred that was detrimental to your database. WITH STOPAT option allows you to restore your database to a point in time.
