Using Microsoft Azure Blob Storage
If you selected Microsoft Azure as a destination storage for your backup, the Backup Wizard provides an extended version of this page enabling you to choose Azure Blob Storage.
You can choose among the following options:
Archive Blob Storage This is a low-cost storage option for infrequently accessed data.
As opposed to hot and cool storage tiers, fetching data from an archive storage takes up to several hours.
Cool Blob Storage Cool storage tier has lower storage costs and higher access costs compared to hot storage. This tier is intended for data that will remain in the cool tier for at least 30 days.
This feature is only supported for General Purpose v2 Azure accounts. If you are using another kind of account, you need to upgrade your account to be able to use this feature.
Please be informed about the additional charges and increased blob access rates resulting from upgrading your Azure account.
