With the advent of RAID storage devices, is it still necessary to backup an Oracle database? Please be as detailed as possible and type out in text, as handwriting is often difficult to read. Thank you for your time in advance :]
With the advent of RAID storage devices, is it still necessary to backup an Oracle
RAID
RAID ("Redundant Array of Inexpensive Disks" or "Redundant Array of Independent Disks" is a data storage virtualization technology that integrates several physical drive modules into one or more logical drives, for the purposes of data replication, performance optimization, or the two (SLED)
Data is spread across the drives in one way or another, called RAID stages, based on the redundancy and efficiency necessary. The numerous schemes or layouts of the data distribution are called by the term "RAID" followed by a number like RAID 0 or RAID 1. A particular balance between the main priorities of reliability, availability, efficiency, and capability is sought in each RAID or scheme. RAID thresholds above RAID 0 guard against irreversible sector reading errors and physical drive failures.
Oracle database
Oracle Database is a multi-model database management system developed and marketable by Oracle Corporation, also referred to as Oracle DBMS or simply Oracle Database.
It is a common database used in the online computing (OLTP) and mixed (OLTP/DW) database processing. Oracle Database is available on-prem, on-cloud or as mixed cloud installation to various service providers. It can be run on servers of third parties and on Oracle hardware (exadata on prem, on Oracle Cloud or on Client Cloud).
