Which two restrictions apply when the RMAN BACKUP AS COPY command is used to create a backup? (Choose two.)
When using the RMAN BACKUP AS COPY command to create backups, two restrictions apply: Binary compression cannot be applied to the backup, and backups can be written only to disk. Image copies created with the BACKUP AS COPY command are bit-for-bit copies of database files, and these copies cannot be compressed. Additionally, these backups must be written to disk rather than media such as tapes.
image copies cannot be compressed nor backup on tape

Image copies are identical to copies created with operating system commands like cp on Linux or COPY on Windows, but are recorded in the RMAN repository and so are usable by RMAN. You can use RMAN to make image copies while the database is open.
