There are three types of Recovery Models in SQL Server:-
1) Full Recovery Model
2) Bulk-logged Recovery Model
3) Simple Recovery Model
Full Recovery Model:-
In this Model, we can take FULL, Differential & Log backups . Every transaction in is logged in the databases log file.
Bulk-logged Recovery Model
In this Model, we can take FULL, Differential & Log backups. The main difference between Full & Bulk logged is that all the Bulk Load operaions are minimally logged into the log file of the databases. In other words , we can say that only the allocation & deallocation of pages that aee affected with the Bulk operations are logged into the log file.
Simple Recovery Model
Under this recovery model, we are only capable of taking Full & Differential backups of the databases. Log backup is not possible in this recovery model.
