Archiving to Microsoft Azure

In this post, we are going to look into how to replace traditional physical tape and use the public cloud to store long-term archival data. We will look into using Microsoft Azure Storage - Cool Storage Tier. Currently when writing this post Archive Storage Tier is not available in South East Asia Region.

Microsoft Azure Blob storage is divided into 3 tier
a) Hot Tier - optimize to store data that frequent use
b) Cool Tier - storing data that is infrequent access and stored for at least 30 days
c) Archive Tier - optimize to store data that is rarely accessed and stored for at least 180 days

To calculate the cost of Azure Blob Storage according to tier, you can refer to https://azure.microsoft.com/en-us/pricing/details/storage/blobs/
