Author A question on when to use bulk logged recovery mode
Simon Harvey

2006-12-14, 5:25 am

Hi all,

I was hoping that someone could tell me a couple of scenarios where the
bulk logged recovery mode is used and perhaps why?

I'm guessing you might use it just before doing a large data import, but
does that mean you might switch to it before the import and switch back
to full recovery once it's done? Is that a good idea?

What other instances might it be used? Perhaps in a reporting database
for some reason?

Many thanks to anyone who can advise

Kindest Regards

BOL says
In Microsoft® SQL ServerT 2000, you can switch between full and bulk-logged
recovery models easily. It is not necessary to perform a full database
backup after bulk copy operations complete under the Bulk-Logged Recovery
model. Transaction log backups under this model capture both the log and the
results of any bulk operations performed since the last backup.

There are some operatuions like SELECT INTO..,CREATE INDEX under BULK
logged recovery mode are minimally loggged.


A disadvantage is that you cannot restore LOG file at point of time
