2020年8月27日 · RPO, RTO, and MTD are most frequently used in business continuity and are usually defined during the Business Impact Analysis (BIA). They are important measurements to ensure the requirements for a business process or function will be achieved by current systems and procedures.

2022年10月27日 · 在MySQL中，RPO（Recovery Point Objective）和RTO（Recovery Time Objective）是两个重要的指标，用于评估系统的恢复能力和数据丢失程度。RPO是指允许的数据丢失时间，RTO是指恢复系统所需的最长时间。下面将介绍如何查看MySQL的RPO和RTO。

RTO (Recovery Time Objective): Maximum acceptable downtime; 举个例子，比如某个数据库实例，每24小时备份一次，有天该数据库所在盘损坏了，需要依据备份重启，重启时间为5分钟。那么该系统的 RTO = 5 mins，RPO = 24 hours。

MTD is the maximum amount of time an application or data can be unavailable to users, as specified by business management. This is based on the impact on business functions, and analysis of anticipated lost revenue and other costs that are incurred for every hour, day, or week a given application or database might be unavailable.

2025年3月7日 · RTO defines how quickly you must restore service. RPO determines how much data loss is acceptable. MTD establishes the absolute maximum downtime you can tolerate. For institutions, getting these numbers right is crucial—not just for operational resilience but also for regulatory compliance.

2013年12月10日 · The sum of RTO and WRT is defined as the Maximum Tolerable Downtime (MTD) which defines the total amount of time that a business process can be disrupted without causing any unacceptable consequences. This value should be defined by the business management team or someone like CTO, CIO or IT manager.

2020年3月19日 · 恢复时间目标（rto）。 rto定义在对其他系统资源、支持的任务/业务流程和mtd产生不可接受的影响之前，系统资源可以保持不可用的最长时间。 确定信息系统资源rto对于选择最适合满足mtd要求的适当技术很重要。 恢复点目标（rpo).

2020年3月28日 · RTO: Recovery Time Objective, 讓系統重新上線的時間. WRT: Work Recovery Time, 讓所有業務和作業, 回到事故發生前的水平 (恢復SLA), 所需的時間. MTD: Max Tolerable Downtime, 可容許的最長系統 Down Time. 用自己的理解, 重畫了一張圖, 再搭配上面的翻譯說明, 感覺比較清楚一點

The term Maximum Tolerable Downtime (MTD) is defined and discussed in relation to Recovery Time Objective (RTO) and Recovery Point Objective (RPO). The BIA discussion addresses the differences between BIAs required for systems and those required by Federal Continuity Directives (FCD) -1 and 2 for Continuity of
