In general, backup and recovery refers to the various strategies and procedures involved in protecting database against data loss and reconstructing the database after any data loss. Because data is the heart of the enterprise, it’s crucial for us to protect it. And to protect our organization’s data, we need to implement a data backup and recovery plan. Backing up files may protect against accidental loss of user data, database corruption, hardware failures, and even natural disasters. We have to make sure that backups are done and the backup tapes are stored in a secure location.
A backup is a copy of data from your database that can be used to reconstruct loss data. Backups are be divided into physical backups and logical backups. Physical backups are backups of the physical files used in storing and recovering your database, such as datafiles, control files, and archived redo logs. Ultimately, every physical backup is a copy of files storing database information to some other location, whether on disk or some offline storage such as tape. Logical backups contain logical data (for example, tables or stored procedures) exported from a database with an Oracle export utility and stored in a binary file, for later re-importing into a database using the corresponding Oracle import utility.
Data recovery is the process of salvaging and handling the data through the data from damaged, failed, corrupted, or inaccessible secondary storage media when it cannot be accessed normally. Often the data are being salvaged from storage media such as internal or external hard disk drives, solid-state drives (SSD), USB flash drive, storage tapes, CDs, DVDs, RAID, and other electronics
