Can we take log backup in bulk log recovery model?

It is important to note that you can indeed recover a transaction log containing bulk logged operations but not to a particular point in time. Instead you can take a transaction log backup as soon as the bulk operation is finished and regain PIT recovery.

What is bulk logged recovery model?

The bulk-logged recovery model is designed for intermittent use to improve the performance of bulk imports of large amounts of data. It’s practically the same as the full recovery model with the only exception that under the bulk-logged recovery model some operations are logged minimally.

What is the difference between full and simple recovery model?

Why use bulk logged recovery model?

What are the three types of recovery?

What are the disadvantages of setting a database to use bulk logged recovery model?

Bulk-logged operations perform much better because of minimal logging and as minimal transaction log space is used. Disadvantage – You will lose any data modifications made between the time of the latest full/differential backup and the time of the failure when you want to restore.
