What is the correct commands for backing up a production Oracle 11g database (while still running) to an external USB drive or different directory.
I am new to Oracle and but have experience with SQL Server. Essentially, I am looking for the equivalent of a COPY_ONLY backup - something which will not interfere with the existing backup process.
The goal is to take the backup offsite and use it to develop migration scripts for a new application. Any insights would be appreciated.
