I right clicked the database ->tasks -> copy database and created a copy.

I noticed the copy is about two times bigger in size (mb). Why’s that ?

    I’m guessing that the MDFs will be similar (same data) but the LDF is larger because of logging of population of data. Run this per database:

    SELECT size/128.0 AS MB, name, physical_name FROM sys.database_files

    Also, what are the recovery models? If the new one is FULL then the LDF will grow until a log backup happens (I suspect the “old” one has been truncated or such), Check with:

    SELECT recovery_model_desc, name FROM sys.databases
