I need to transfer data from one table to the same table in another server which has been truncated. What is the easiest way to do this?
Depending on the amount and frequency of your data transfer. It it's a low volume one time process, you're better off with using T-SQL to directly insert the data. This can be done either through linked servers or OPENQUERY clause.
If its high volume one time process, use SSIS or BCP utility.
If its high volume high frequency, use replication.
