The terminology commonly used in Backup is explained:

Cold backup (Offline Backup): A physical copy of a database that is in a closed state. The database is in non-archive mode and can only be backed up using this method.

Database full backup: Backs up all data files and control files, the database can be turned off or turned on during full backup, but must be turned off in non-archive mode.

Data file backup: Backup a single data file, in non-archive mode, can only back up read-only data files or normal offline data files.

Specific steps for cold backup (offline Backup):

1. Use SELECT * from V$controlfile to isolate all control files.

2. Use SELECT * from V$logfile to find all redo log files.

3. Use SELECT * from Dba_data_files to find all data files.

4. Use SELECT * from V$tempfile to find all temporary files.

5. Gracefully shut down the database and copy all files to the backup disk.

6. Restart the database.

Steps to recover:

1. Gracefully shut down the database

2. Put all the backup files in the original location (redo log files, parameter files and password files are not required)

3. Restart the database
