Description

Fully backup a managed HSM to a storage account. Use Restore-AzKeyVault to restore the backup.

Examples

Example 1 Backup an HSM to Storage Container using SAS token

$sasToken = ConvertTo-SecureString -AsPlainText -Force "?sv=2019-12-12&ss=bfqt&srt=sco&sp=rwdlacupx&se=2020-10-12T14:42:19Z&st=2020-10-12T06:42:19Z&spr=https&sig=******"

Backup-AzKeyVault -HsmName myHsm -StorageContainerUri "https://{accountName}.blob.core.windows.net/{containerName}" -SasToken $sasToken

https://{accountName}.blob.core.windows.net/{containerName}/{backupFolder}

The cmdlet will create a folder (typically named mhsm-{name}-{timestamp}) in the storage container, store the backup in that folder and output the folder URI.

Example 2 Backup an HSM to Storage Container via User Assigned Managed Identity Authentication

# Make sure an identity is assigend to the Hsm
Update-AzKeyVaultManagedHsm -UserAssignedIdentity "/subscriptions/{sub-id}/resourceGroups/{rg-name}/providers/Microsoft.ManagedIdentity/userAssignedIdentities/{identity-name}"
Backup-AzKeyVault -HsmName myHsm -StorageContainerUri "https://{accountName}.blob.core.windows.net/{containerName}" -UseUserManagedIdentity

https://{accountName}.blob.core.windows.net/{containerName}/{backupFolder}

The cmdlet will backup the hsm in specific Storage Container and output the folder URI via User Assigned Managed Identity Authentication. The Managed Identity should be assigned access permission to the storage container.

Example 3 Backup an HSM to Storage Container using Storage Account Name and Storage Container

Backup-AzKeyVault -HsmName myHsm -StorageAccountName "{accountName}" -StorageContainerName "{containerName}" -UseUserManagedIdentity

https://{accountName}.blob.core.windows.net/{containerName}/{backupFolder}

The cmdlet will create a folder (typically named mhsm-{name}-{timestamp}) in the storage container, store the backup in that folder and output the folder URI.
