https://uplatz.com/course-details/ora... | This video tutorial is all about the Backup and Recovery whose procedures to protect your database against data loss and reconstruct the data, should loss occur.

A backup is a copy of data. This copy can include important parts of the database, such as the control file and data files. A backup is a safeguard against unexpected data loss and application errors. If you lose the original data, then you can reconstruct it by using a backup. Recovery Manager (RMAN) is an Oracle utility that can back up, restore, and recover database files. It is a feature of the Oracle database server and does not require separate installation.

To restore a physical backup of a data file or control file is to reconstruct it and make it available to the Oracle database server. To recover a restored data file is to update it by applying archived redo logs and online redo logs, that is, records of changes made to the database after the backup was taken. If you use RMAN, then you can also recover data files with incremental backups, which are backups of a data file that contain only blocks that changed after a previous incremental backup.

As a backup administrator, your principal duty is to devise, implement, and manage a backup and recovery strategy. In general, the purpose of a backup and recovery strategy is to protect the database against data loss and reconstruct the database after data loss. Typically, backup administration tasks include the following:

• Planning and testing responses to different kinds of failures
• Configuring the database environment for backup and recovery
• Setting up a backup schedule
• Monitoring the backup and recovery environment
• Troubleshooting backup problems
• Recovering from data loss if the need arises
