Hi,
I got a database of 20gb . Now i want to perform ETL process on that database so as to copy that entire database into another server.Approximately how much time it will take for that job to be completed.

Since the plan appears to be to refresh 100% of the database I would call it extreme ETL 😀
Answering your question... how long it takes to take a full backup and restore of your database? The elapsed time is your answer 😉

Have to agree with Paul.
ETL for a whole db doesnt really make sense.
Backup and restore would be a good idea.

Since you're copying the entire database, why not simply run a backup and restore?

How often and why do you want to do this?
Maybe what you are looking for is log shipping or some other form of replication.
As for the how long - try a 2gb file as a test. How fast depends a lot on your hardware setup.
I got about 100GB in 30 minutes in my environment when I recently did that for a server build.
