10.2 Back up the d<strong>at</strong>abase using TDP for <strong>Oracle</strong> and RMAN<br />
Performing a backup with RMAN cre<strong>at</strong>es a backup set for th<strong>at</strong> oper<strong>at</strong>ion. A<br />
backup set contains backups of one or more d<strong>at</strong>a files or archive logs. A d<strong>at</strong>a<br />
file backup sets can also include a control file backup. Archive log backup<br />
sets can only include archive logs. D<strong>at</strong>a file backup sets can be incremental<br />
or full and do not include empty blocks. A backup set is a logical entity<br />
composed of one or more physical output files called backup pieces. Each<br />
backup piece contains control and checksum inform<strong>at</strong>ion th<strong>at</strong> allows the<br />
<strong>Oracle</strong> server process to valid<strong>at</strong>e the backup piece during a restore. A<br />
backup set is cre<strong>at</strong>ed by the backup command. A restore command is<br />
required to extract files from a backup set.<br />
10.2.1 Full backup<br />
A full backup is a non-incremental backup of one or more d<strong>at</strong>a files. A full<br />
backup has no effect on incremental backups and is not considered to be part<br />
of the incremental str<strong>at</strong>egy.<br />
If the d<strong>at</strong>abase is in ARCHIVELOG mode, you can choose to do full backup<br />
while the d<strong>at</strong>abase is online or offline. If the d<strong>at</strong>abase is in NOARCHIVELOG<br />
mode, the d<strong>at</strong>abase must be closed by a clean shutdown. Full backups can<br />
be taken of:<br />

Control files<br />
Archive logs<br />
