JUNE 25, 2020

This means that Dynatrace continues full operation when a majority of nodes are up and a maximum of two nodes are down at a time. The network latency between cluster nodes should be around 10 ms or less. Minimized cross-data center network traffic. Automatic recovery for outages for up to 72 hours.

An incremental backup, which is faster and requires less storage than a full backup, captures changes made since the previous backup. This helps minimize downtime.
