STILL WITHIN RMAN, RUN THIS COMMAND TO LIST YOUR BACKUPS

4. Still within RMAN, run this command to list your backups:

list backup of database;

You will see the first backup, made in Exercise 15-1, is incremental level 0 and

will be over 1GB. The second backup is incremental level 1, and only a few

megabytes. This is because very little data has been changed between the two

backups. But note that the time taken did not drop proportionately.
