The restore part of this equation has nothing to do with the lock conflict.
That's my point... Unless you are restoring over the top of an existing
The restore operation is totally exclusive of any access to the database in

I will explain once again

Every day at 22:00 we perform gbak �b �g and restore to different database

Once per year we stop production and perform the same procedure as above.
Then we rename active (stopped) database to different name and rename
restored database to active database.
And start the production again.

I was just asking if possibility exists that backup (just �b) has influence
on currently active transactions
because lock conflicts begin to happen at exact time when backup is


I would never perform restore over an active database (I'm too long in this
business :-))
