History data storage levels

Each time a Flow executes there is the option of storing snapshot data. Snapshot data consists of

The Flow execution log (what you see in the bottom right editor pane).
Edge data - the data object that is stored on each edge when the Flow terminates.
The termination status - OK, Fatal, Timed out.

There are two primary consideration when choosing whether to store snapshot data or not.

Security - if you have strict security requirements, you may not want to store any data in the database at all - especially when running in production mode.
Storage space - if you are running large numbers of executions, each snapshot will take up space in the database. So, you will often only want to store snapshot data for errored or timed-out executions.

Specifying history snapshot levels

There are two places to specify this.

in the Global Settings, you can specify the default for all Flows. If an individual Flow does not specify the level, then it will use this.

Open the Flow Settings to select a snapshot level for an individual Flow.
