Snapshots

In This Guide

Overview

A snapshot represents the state of a disk or virtual machine at a given moment in time. It is separate to the backups concept to which the differences can be read about below. A snapshot allows you to capture a disk or virtual machine's current state in case it should need to be rolled back - ideal for those just in case it might break moments. Katapult creates a daily snapshot for every disk which is kept until the next automatic snapshot is taken the following day.

Backups vs Snapshots

A comparison on the two can be found in the backups how-to guide. It's worth a read to help your understanding of the two concepts within Katapult.
