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.

Recovery procedures: A set of actions that are taken in the event of a disaster or other catastrophic event to ensure the continuation of critical business functions. Recovery procedures are used in disaster recovery planning and business continuity planning. Examples include having backup power generators, implementing data backups, and having a communication plan in place.
