Is there any predefined window to show database backups?
Sorry, there is not.
Too bad because this is very important for every Dba.
The Editor does support RMAN commands though.
If you have RMAN configured, you can just
- go to the Editor
- right-click on the tab "New 1" and choose "New Tab" -> RMAN
- type in rman list and then run it.
(You may have to configure the path to rman in options -> executables)
