- Do you really need to backup your storage account?
Azure storage account has different replication options for you, please take a look at the following two articles to see if you really need to do the backup, if the storage account replication, for example: RA-GRS, meets your requirement, you don’t need to do backup.
What to do if an Azure Storage outage occurs
- Backup Virtual Machine or backup Storage Account?
- Azure storage account has two types, standard storage and premium storage, premium storage is only for page blob, which means it’s design for high performance Virtual Machine, if you would like to backup premium storage account, please use Azure Recovery Vault to backup Virtual Machines in the storage account, which gives your flexibility and rich features to do backups and restore.
Back up Azure virtual machines
- If your purpose of storage account backup is only for Virtual Machine, I also recommend use above link.
- There is no build-in function in Azure to backup a storage account, because a storage account has different type contents: blob, table, queue and files, you need to design different solution for different content.
- Best Practices for protecting your data
• VM Disks – Use the Azure Backup service to back up the VM disks used by your Azure virtual machines.
• Block blobs –Create a snapshot of each block blob, or copy the blobs to another storage account in another region using AzCopy, Azure PowerShell, or the Azure Data Movement library.
• Tables – use AzCopy to export the table data into another storage account in another region.
• Files – use AzCopy or Azure PowerShell to copy your files to another storage account in another region.
