Worldwide RMAN Online Backup
To understand RMAN Online Backup, you must first be familiar with Oracle Databases. There are many sorts of databases available to businesses of many sizes, but Oracle is the world's most popular database. Oracle Databases are used by companies for all types of enterprises, from rocket science to retail. RMAN, short for Recovery Manager, is a program tool that accompanies and is for use exclusively with Oracle Databases.
RMAN is a data storage and recovery tool ideal for businesses who do not wish for their data to be stored and managed in remote locations off-site, but in-house, by their own Information Technology specialists. Therefore, the term "Online" within "RMAN Online Backup" refers not to the Internet, but to a data backup method which is performed by IT personnel while the Oracle Database is running (that is, while employees are working), as opposed to "off-line" backup, which is performed while the Oracle Database software is not running.
RMAN Online Backup works in tandem with Oracle Secure Backup to protect data by storing it on magnetized tape. As RMAN is a tool already integrated into the Oracle Database software, RMAN Online Backup is an economical data protection solution for many companies, who must only further invest in their data backup strategy through tapes and tape drive hardware. Tapes are a viable means of data storage and recovery, although companies are responsible for how and where the tapes themselves are managed and stored.
The primary function of RMAN within the RMAN Online Backup process is file multiplexing and compression for more efficient data storage and recovery. It can also detect block-level corruption of data. RMAN Online Backup can be used to perform either incomplete or complete recovery of files, with "complete" referring to data being restored to its most current state in storage, and "incomplete" referring to data being restored to a specified, previous point in time. Thus, depending on how closely IT personnel monitor the RMAN Online Backup system, it can be considered continuous data protection which can be quickly recovered in the event of data loss. RMAN Online Backup is a data protection solution that can be used by small, mid-sized, and enterprise businesses alike. Any company who uses the Oracle Database can use RMAN Online Backup. In many cases, it can be an affordable alternative to costly off-site data storage, management, and recovery.
