Closely Related Concepts
Recovery time (or estimated time of repair (ETR), also known as recovery time objective (RTO)) is closely related to availability, that is the total time required for a planned outage or the time required to fully recover from an unplanned outage. Recovery time could be infinite with certain system designs and failures, i.e. full recovery is impossible. One such example is a fire or flood that destroys a data center and its systems when there is no secondary disaster recovery data center.
Another related concept is data availability, that is the degree to which databases and other information storage systems faithfully record and report system transactions. Information management specialists often focus separately on data availability in order to determine acceptable (or actual) data loss with various failure events. Some users can tolerate application service interruptions but cannot tolerate data loss.
A service level agreement ("SLA") formalizes an organization's availability objectives and requirements.

“Lust and self-mutilation are closely related impulses. There are also self-mutilators among knowers: they do not want to be creators under any circumstances.”

“Out of all those centuries the Greeks can count seven sages at the most, and if anyone looks at them more closely I swear he’ll not find so much as a half-wise man or even a third of a wise man among them.”
—Desiderius Erasmus (c. 1466–1536)
“In the middle years of childhood, it is more important to keep alive and glowing the interest in finding out and to support this interest with skills and techniques related to the process of finding out than to specify any particular piece of subject matter as inviolate.”
—Dorothy H. Cohen (20th century)
“It is impossible to dissociate language from science or science from language, because every natural science always involves three things: the sequence of phenomena on which the science is based; the abstract concepts which call these phenomena to mind; and the words in which the concepts are expressed. To call forth a concept, a word is needed; to portray a phenomenon, a concept is needed. All three mirror one and the same reality.”
—Antoine Lavoisier (1743–1794)
