:command:`crosscheck backup`
    Verifies that the backups that rman thinks are available actually are. 
    Lists any that aren't as expired with a 'X' in the status column.

:command:`crosscheck backup completed between 'sysdate-5' and 'sysdate-2';`
    Verifies that the backups that rman thinks are available actually are. 
    Lists any that aren't as expired with a 'X' in the status column.

:command:`validate backupset ##`
    Verifies the backupset identified by ## can be restored. Throws an error 
    if it can't be.

:command:`list backup`
    Very verbose listing of all backups of which rman knows. Rather 
    unreadable output

:command:`list backup summary`
    A much more readable version of the above. Useful for gettng the backup 
    set key from which you can get a more detailed and readable report.

:command:`list backup of [ tablespace ${ts} | datafile # ] [ summary ]`
    Lists backups that have tablespace or datafile specifically. Useful for 
    finding the latest backup of the tablespace for tspitr, for example.

:command:`list backupset ##`
    Much more readable version of list backup

:command:`list incarnation [ of database ]`
    Lists the incnations of the database, information of which will be 
    needed if you need to restore through a resetlogs

:command:`list archivelog all`
    Lists the archivelogs in the FRA(?) that haven't been backed up yet.

:command:`list backup of archivelog all [ summary ]`
    Lists the backups of the archive logs.

:command:`report need backup [ days | incremental | redundancy ]`
    Reports on the datafiles that need to be backed up. W/o args, uses the 
    default retention period.

:command:`report obsolete`
    IDs the backups that are considered obsolete based on the configured 
    retention policy

:command:`report schema [ at [ time | SCN | sequence ]`
    Displays the database schema. In order to use the 'at time' syntax, need 
    to be connected to a recovery catalog.

:command:`report unrecoverable`
    Reports any datafiles, tablespaces, etc, that are unrecoverable. Would 
    seem to be a fairly important command.

:command:`delete obsolete`
    Deletes backupsets that are considered obsolete based on the configured 
    retention policy

:command:`delete backupset ##, ##, ##`
    Deletes specific backupsets.
