Both differential and cumulative backup work with compressed option in 11G.

Both differential and cumulative backup work with compressed option.
backup as compressed backupset INCREMENTAL LEVEL 1 CUMULATIVE database plus archivelog delete all input;
backup as compressed backupset INCREMENTAL LEVEL 1 database plus archivelog delete all input;
The cumulative backup takes more diskspace.
If we want to minimize the performance downgrade when running backup I suggest to use differential backup every working day and do the LEVEL 0 at weekend.
The Level 1 will work as level 0 automatically if level 0 backup does not find.
Also the rman won't delete the archive logs needed by the upstream.

See the test:
