I am using SQL Server 2005. Since i do some development work so i create the replica of my live databases to run for trial. When i restore the data from the live one to the test one it increases the size of the log file very much which is occupying the space unnecessarily. I am trying to get rid of the log file and create a new one. What I have done so far is detach the database, delete the .ldf file and when i try to attach the database it says the .ldf file is not present. Could any body help me with this

Restore the database as usual.  Put the database in Simple recovery mode.  Then, run DBCC SHRINKFILE and shrink the .ldf.

You can't just get rid of it and create a new one.

Put the database in the developement stage in SIMPLE RECOVERY MODEL, This will truncate the Transaction Log everytime the engine do checkpoint.

Don't forget to shrink the transaction log ( DBCC SHRINKFILE ('LOGICAL_NAME_OF_TRANSACTION_LOG') )

If you are going to use Full Recovery Model, than you need to get in the habit of backing up the Transaction Log as well as the database.

Could any body please explain me clearly what is 'Simple Recovery Model' and 'Full Recovery Model'. What option do I need to select for that.

Kind Regards
