The Recovery Point Objective (RPO) value tells you the point in the past at which data can be recovered; in other words, the maximum amount of downtime and, therefore, data loss. Thus, RPO is a key indicator of data availability.

If we know the RPO of a given part of our IT infrastructure, we can estimate how much data we will lose if a particular node fails. However, different backup types affect the length of downtime. For example, synchronous backups allow data to be restored almost instantly, but with asynchronous backups, there will be some delay.

There are also countless options for specific backup solutions. Nevertheless, the RPO should be kept as low as possible when it comes to key operational data. The RPO is also closely related to the RTO (Recovery Time Objective); however, the RTO does not refer to the time of failure but to the duration of the recovery process itself.
