Storage
How backup data can be stored in your Azure blob storage?
If you are using your own Microsoft Azure Blob Storage (BYOS subscription), you may be interested in how the backup data is stored in Azure Blob storage.
For BYOS customers using Azure Blob storage, AvePoint will write your new backup data to the cold tier by default to reduce storage costs. The supported Azure storage account types are StorageV2 and BlobStorage of Standard performance type. For existing customers, your former backup data are still stored in the cool tier. This intelligent tiering also extends to additional BYOS storages appended to the system.
To use your Azure blob storage in the most cost-effective manner, you can also store the backup data in the archive tier. For new customers after the December 2023 release, AvePoint will set archives to old backup cycles if the new backup cycle starts more than 180 days by default. If you are an existing customer with the archive settings configured before, you will continue with your current setup.
| Hot Tier | Cold Tier | Archive Tier |
|---|---|---|
| Index database | The backup job stores backup data to the cold tier automatically from the December 2023 release and will always keep at least a full backup cycle in the cold tier. | Older backup data can be moved to the archive tier. |
Does Cloud Backup use HTTPS (SSL) for Amazon S3 communication?
Yes. Cloud Backup for Microsoft 365 uses HTTPS (SSL) instead of HTTP to access Amazon S3 by default. For details on Amazon S3 storage configuration, refer to Storage Information.
Will your backup services incur additional costs on BYOS storages during backup and restore?
Yes. For example, for BYOS customers with Microsoft Azure Blob Storage, below are the main factors to consider:
| Additional Costs | Comment |
|---|---|
| Data storage | The cost to store backup data. For information on storage tiers for different storage types, refer to Storage Information. |
| Data read & write operations | During a backup job in Cloud Backup, data will be written to the customer's BYOS storage. Similarly, during a restore job, data will be read from the storage. Data are stored in blobs which are around 10 to 50 MB in size. Each blob will incur one operation. |
| Data retrieval | Additional costs apply for data retrieval during restore jobs. These costs vary depending on the storage tier. |
| Data transfer | The primary cost concern is data transfer out. If your default Azure Blob Storage is the same region as the data center you signed up for AvePoint Online Services, there will be no transfer costs. Otherwise, additional charges will be incurred. |
