- Raw Disk Storage Storage access mode where the operating system and applications interact directly with the disk sectors, bypassing typical file system structures. This provides finer control over the data storage and retrieval process, utilized in scenarios requiring tailored data management, such as certain database systems or specialized data processing applications.
- Read The act of accessing and retrieving data from a storage location. It is used in computing to access information from a variety of sources, including memory, disk, or network. Examples of reading include accessing a file on a computer's hard drive or reading data from a database.
- Read Access The permission to access and retrieve data from a storage location. It is used in security to control who can access sensitive information. Examples of read access include allowing only certain users to view sensitive financial data or restricting access to confidential documents.
- Real User Monitoring (RUM) A performance measurement technique that tracks the user experience of a website or application in real-time from the user's perspective. It is used in web development and user experience design to identify and diagnose performance issues, such as slow page loads, errors, or crashes. Examples include using RUM tools to monitor the end-to-end user journey, including the network, server, and browser components, and using RUM data to identify and optimize performance bottlenecks or user pain points.
- Reasonable actions Actions that are considered appropriate given the specific circumstances and are based on common sense and sound judgment. It is used in information security to determine the necessary measures that need to be taken to protect data and systems from potential threats. Examples include implementing multi-factor authentication, conducting regular security assessments, and implementing robust access controls.
- Reconstitution The process of restoring data or systems to a previous state. It is used in disaster recovery and backup to ensure that critical information can be recovered in the event of a failure. Examples of reconstitution include restoring a database from a backup or rebuilding a server from a system image.
- Recovery The act of restoring data or systems to a previous state. It is used in disaster recovery and backup to ensure that critical information can be restored after a failure. Examples of recovery include restoring a database from a backup or rebuilding a server from a system image.
- Recovery action A specific step or task that is performed as part of the recovery procedures in the event of a disaster or other catastrophic event. Recovery actions are used in disaster recovery planning and business continuity planning to ensure the successful implementation of recovery procedures. Examples of recovery actions include restoring data from backups, activating a disaster recovery site, and communicating with employees and customers.
- Recovery agent An individual or team responsible for coordinating and executing recovery processes. It is used in disaster recovery to ensure that critical information and systems can be restored in the event of a failure. Examples of recovery agents include a disaster recovery team or a system administrator responsible for restoring backups.
- Recovery Point Objective (RPO) The maximum tolerable amount of data loss measured in time. It is used in disaster recovery planning to determine how often data backups should be made and how much data can be lost in the event of a disaster. Examples of RPOs include a daily backup for a financial system to ensure no more than one day's worth of transactions are lost or a weekly backup for a non-critical system that can tolerate losing up to a week's worth of data.
