Q:

What is Log Shipping?

Answer

Log shipping defines the process for automatically taking backup of the database and transaction files on a SQL Server and then restoring them on a standby/backup server. This keeps the two SQL Server instances in sync with each other. In case production server fails, users simply need to be pointed to the standby/backup server. Log shipping primarily consists of 3 operations:


Backup transaction logs of the Production server.


Copy these logs on the standby/backup server.


Restore the log on standby/backup server.
