RMAN: backup set

A backup set is a logical structure that contains the data of one or more Oracle files ( data file, control file, online redo log file, server parameter file).
A backup set consists of one or more physical binary files in a proprietary data format that is only readable and writable by RMAN. These files are referred to as backup pieces.
A backup set is created with the RMAN backup command.
Image copies cannot be written into a backup set. They can only be written to disk.

RMAN commands

configure device type disk backup type to            backupset; # implicitly uncompressed
configure device type disk backup type to compressed backupset;
configure device type sbt  backup type to compressed backupset;
