Hi,

I created a new test server. i took incremental level 0 backup from prod database and restore the test database. next day i took level 1 backup from prod database and restore to test database. after restoring level 1 backup no changes in the test database, old data only available in the test database.

database version : 11.2.0.3 standard editionhttps://www.google.co.in/search?q=11.2.03+standard+edition&spell=1&sa=X&ved=0ahUKEwj8wZCbvJ_XAhWILo8KHYvjD-UQvwUIIigA
