one of the useful RMAN commands is:

RMAN> list backup summary;

so what are these columns represent ?

* LV column lists the following:

0 = incremental level 0 backup

1 = incremental level 1 backup

A = archivelogs

f = full – backup database command

* S is the status:

A = available

U = unavailable

As mentioned above F can represent either “FULL” backup or “Control File” Backup. If your RMAN configuration for controlfile auto-backup is set to “ON” , the control file backup will be taken automatically each time RMAN backup runs as shown in the above picture.

The RMAN configuration is:

RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON;
