Autoscaling

Autoscaling grows and shrinks your datastore with your storage usage.

Setup

You can turn autoscaling on or off. When it is off, the size of the datastore never changes. You can also turn off only the scale-down. Then the datastore never gets smaller unless you change its size by hand.

Two thresholds (percentages of the datastore size) control when autoscaling acts. For example, a lower threshold of 70% on a 1 TB datastore means: when less than 70% (700 GB) is used, the datastore scales down.

This graph shows how the datastore size follows the usage over time:
