Rman Full Backup With Archivelog And Controlfile

An RMAN full backup backs up all files and datafiles in the database. It also backs up the control file and the online redo logs.

An RMAN full backup with archivelog mode creates an online redo log backup as well. This backup is necessary to keep the database consistent if you need to restore from a previous backup.

An RMAN full backup with controlfile mode copies the control file to a backup location. This is necessary if you need to restore the control file to a previous version.

Which RMAN command takes Controlfile and Spfile backup?

The RMAN command that takes a backup of the control file and SPFILE is BACKUP CONTROLFILE and SPFILE. This command can be run from either the RMAN command line or from a script. The syntax for the command is:

BACKUP CONTROLFILE and SPFILE

The BACKUP CONTROLFILE and SPFILE command will back up the control file and SPFILE to the default backup location. If you want to specify a different backup location, you can use the BACKUP DATABASE command with the CONTROLFILE and SPFILE keywords. The syntax for the BACKUP DATABASE command is:

BACKUP DATABASE

CONTROLFILE and SPFILE

The CONTROLFILE and SPFILE keywords tell the BACKUP DATABASE command to back up the control file and SPFILE. The backup will be placed in the default backup location.

How do I run a full backup of RMAN?

A full backup of your RMAN environment backs up all files and data that are needed to restore your environment.

To run a full backup of RMAN, follow these steps:

1. Connect to your RMAN environment.

2. Run the BACKUP command to back up all files and data.

3. Verify that the backup was successful.

4. Disconnect from your RMAN environment.

Which RMAN command is used to create a full backup?

There are a number of RMAN commands that can be used to create a full backup. The most common command is BACKUP DATABASE. This command will back up the entire database, including all datafiles, controlfiles, and redo logs.

Another common command is BACKUP ARCHIVELOG. This command will back up all archived redo logs. This is useful if you need to restore the database to a specific point in time.

You can also use the BACKUP command to create a full backup. This command will back up all datafiles, controlfiles, and redo logs in a single backup file.

whichever command you use, make sure you have enough space on your backup device to store the backup file.

How do I backup RMAN to a specific location?

Oracle Recovery Manager (RMAN) is a powerful backup and restore tool that ships with Oracle Database. It can be used to create backup sets and image copies of your database datafiles, controlfiles, and redo logs. You can also use RMAN to restore your database to a specific point in time or to a specific point in the past.

One of the great features of RMAN is the ability to backup your database to a specific location. In this article, we will show you how to do this.

To backup your database to a specific location, you need to first create a backup script. This script contains the commands that RMAN will use to create the backup. You can create this script using a text editor, such as vi or Emacs.

Once you have created the backup script, you need to set the RMAN environment to use it. You can do this by running the following command:

RMAN> BACKUP SET ENVIRONMENT=SCRIPT;

This command will set the RMAN environment to use the backup script that you created.

Next, you need to run the RMAN backup command. This command will create a backup of your database to the location that you specify.

For example, if you want to backup your database to the /backups directory, you would run the following command:

RMAN> BACKUP DATABASE PLUS ARCHIVE LOGS TO ‘/backups’;

This command will create a backup of your database and all of the archive logs to the /backups directory.

You can also backup your database to a specific file. For example, if you want to backup your database to the /backups/db.bak file, you would run the following command:

RMAN> BACKUP DATABASE PLUS ARCHIVE LOGS TO ‘/backups/db.bak’;

This command will create a backup of your database and all of the archive logs to the /backups/db.bak file.

You can also backup your database to a remote location. For example, if you want to backup your database to the /backups/db.bak file on a remote server, you would run the following command:

RMAN> BACKUP DATABASE PLUS ARCHIVE LOGS TO ‘tcp://remote.server.com:port/backups/db.bak’;

This command will create a backup of your database and all of the archive logs to the /backups/db.bak file on the remote server.

You can also backup your database to a tape drive. For example, if you want to backup your database to tape drive /dev/tape, you would run the following command:

RMAN> BACKUP DATABASE PLUS ARCHIVE LOGS TO ‘/dev/tape’;

This command will create a backup of your database and all of the archive logs to the /dev/tape drive.

Finally, you can also backup your database to a CD or DVD. For example, if you want to backup your database to CD-ROM, you would run the following command:

RMAN> BACKUP DATABASE PLUS ARCHIVE LOGS TO ‘dvd:/backups/db.bak’;

This command will create a backup of your database and all of the archive logs to the dvd:/backups/db.bak directory.

As you can see, there are many different ways to backup your database to a specific location

What is the difference between a full backup and a whole database backup?

There are two main types of backups: full backups and whole database backups.

A full backup copies all the files and folders on a system. A whole database backup copies the entire contents of a database, including all the data and structures.

A full backup is generally quicker and easier to restore than a whole database backup. However, a whole database backup is more likely to be complete and accurate, as it includes all the data in the database.

What is Level 0 and Level 1 backup in RMAN?

RMAN backups can be classified into three levels: Level 0, Level 1, and Level 2.

Level 0 backups are created by taking a full backup of the database.

Level 1 backups are created by taking a backup of the datafiles and control files.

Level 2 backups are created by taking a backup of the archived redo logs.

The advantage of using Level 0 backups is that they are fast and require less storage space.

The advantage of using Level 1 backups is that they can be used to restore the database to a point in time.

The advantage of using Level 2 backups is that they can be used to restore the database to a point in time and include the archived redo logs.

How do I backup a Controlfile in Oracle?

A Control File is a critical Oracle database file that records the physical structure of the database. It contains the database name, the creation date, the size of the database, the number of datafiles, and the location of each datafile. It also contains a section that lists each of the datafiles in the database and their status.

If the Control File is damaged or lost, you will not be able to open the database. Therefore, it is important to backup the Control File regularly.

The Control File can be backed up using the Oracle Export utility. To backup the Control File, connect to the database using sqlplus and run the export command.

For example, if you want to backup the Control File in the C:\oracle\database folder, you would run the following command:

export CONTROL_FILE=C:\oracle\database\control.ora

If you want to backup the Control File to a different folder, you can specify the folder location in the command.

The Control File can also be backed up using the Oracle Recovery Manager (RMAN) utility. To backup the Control File using RMAN, you must first configure RMAN to connect to the database. For instructions on how to configure RMAN, please refer to the Oracle documentation.

Once RMAN is configured, you can backup the Control File by running the following command:

BACKUP CONTROLFILE TO ‘c:\oracle\database\control.bkp’;
