Click here to read the previous step.

Would you like to create a backup of your datafiles in the flash recovery area directory.?
Just type the following commands, but remember that the target database must be in archivelog mode (alter database archivelog) before running this on-line backup:

$ rman target / nocatalog

using target database control file instead of recovery catalog

Let's gather more information about our database.

Now I choose I want a compressed backup of datafile number 4.

RMAN> run { allocate channel d1 type disk;
2> backup as compressed backupset datafile 4; }

allocated channel: d1
channel d1: sid=159 devtype=DISK

Now I choose I want a compressed backup of the tablespace USERS.

RMAN> run { allocate channel d1 type disk;
2> backup as compressed backupset tablespace users;}

allocated channel: d1
channel d1: sid=159 devtype=DISK

Starting backup at 04-APR-07
channel d1: starting compressed full datafile backupset
channel d1: specifying datafile(s) in backupset

Because datafile number 4 and the tablespace USERS are the same thing, if you want to see
how many backup you have for the datafile number 4, you would see two different compressed backup.

RMAN> list backup of datafile 4;

Now I choose I want a backup of the current control file.

RMAN> run { allocate channel d1 type disk;
2> backup as backupset current controlfile;}

allocated channel: d1
channel d1: sid=159 devtype=DISK

Starting backup at 04-APR-07
channel d1: starting full datafile backupset

And here it's the command to list how many backup I have for my control file.

RMAN> list backup of controlfile;

Now I just delete the backupset files number 4 and 5 and then I run again the same commands above, but this time from a file.

RMAN> delete backupset 4,5;

Edit and prepare a Recovery Manager command file.

vi backup_users.rmn

Then type into it the following rman commands:

run
{
#allocate the channel
allocate channel d1 type disk;

#issue the backup command
backup as compressed backupset datafile 4;
}

Then execute that file using the following command.

$ rman target / nocatalog @backup_users.rmn log=backup_users.log

The log option is useful to analyse your backup status, indeed:

$vi backup_users.log
