Cloud Backup to Azure / Amazon S3 / Wasabi is only available to customers using the Unlimited Plus Edition or Partners using Altaro VM Backup for MSPs.


The below article is a rough guide to Microsoft Azure / Amazon S3 / Wasabi pricing and it's meant to give you an idea of what these providers charge for their storage. If you'd like more accurate pricing kindly consult directly with a member of their team.


Azure


Note that GPv1 (General Purpose v1) is recommended as it will result in the lowest cost. This is due to: "workloads with high churn or high read rates may benefit from this account type." Reference: https://docs.microsoft.com/en-us/azure/storage/blobs/storage-account-options


Altaro VM Backup makes use of General Purpose accounts in Azure, thus costs can be calculated using the below link: https://azure.microsoft.com/en-gb/pricing/details/storage/blobs-general/


Costs will also change depending on the Replication strategy you choose when creating your Azure storage account. You can find more details about the different Replication strategies available in MS Azure here: https://docs.microsoft.com/en-gb/azure/storage/storage-redundancy

Amazon S3


With Amazon S3 storage it's important to note the following:


- [Versioning] must be disabled as this is not supported. 

- [Default Encryption] must be disabled as it is not supported.  Altaro VM Backup already encrypts (256-Bit AES) natively before upload.

- Enabling [Logging] will incur higher costs to the account, thus it is recommended  to disable it

- [Block Public Access] should obviously be enabled since it contains your backup data which should not be publicly accessible

Wasabi


With Wasabi storage it's important to note the following:


- [Bucket Versioning] must be disabled and [Suspend Versioning] is selected as this is not supported. 

- Enabling [Logging] will incur higher costs to the account, thus it is recommended to disable it

- [Public Access] should obviously be disabled since it contains your backup data which should not be publicly accessible

Sample Costs


We have put together a sample for reference as below. Please note that this sample was calculated taking:

  • a backup set of 1TB in total (source size is 3TB, the costs could be less based on block storage Deduplication savings)
  • pricing is using Azure Data Center East US, Amazon S3 Data Center US East (Ohio) and Wasabi Data Center US-East
  • 20GB of changed data being uploaded per day
  • pricing as at 9th August 2019
  • Wasabi has a minimum monthly free of $5.99, this does not include premium support


Please note that this is rough pricing from Microsoft Azure / Amazon S3 / Wasabi with regards to using their storage accounts and this is not Altaro's charge for backing up.
