File Share Snapshot automation - Creation

Introduction

The purpose of this document is to describe the process to take automated on-demand snapshots for Azure File Share.

Snapshot for Azure File Share is now in General Availability. Previously, Azure File Share did not have any backup option. In case of the File Share getting deleted, there was no mechanism to recover the File Share and the data was lost. The File Share Snapshot helps organizations take on-demand snapshot backups of the existing File Share for restoring it later as and when required. This document describes automating this process.
