In that case, you might try what SQL Server itself uses for replication if you have the disk space. BCP in native format. Export the table to a file, then import it in half million (or less depending on the size of your rows) row chunks using the batch size setting. It will keep your log file from exploding.
As an alternative, you could have the infrastructure folks do what I believe is called a "SAN Snapshot" to copy the mdf and ldf files and then simply attach the database.
As jeff sugested , taking a SAN snapshot and then attaching the mdf / ldf file could save time and will be a good approach.

I have some recommends here:
1-Choose the point time when your server does not work hard
2-Separate your table into smaller pieces (may be multiple files) and using a package to transform data

Hi,
We decided to insert the info using
BEGIN TRANSACTION
INSERT INTO DB2.dbo.Table
SELECT *
FROM DB1.dbo.Table
WHERE CodigoCaso < @cont and CodigoCaso > @ultimo
SET @ultimo = @cont
SET @cont = @cont + 1000
COMMIT TRANSACTION
In order to avoid a huge increase in the log file.
I will post the result
Thanks
