Restore Azure file shares with the Azure CLI

The Azure CLI provides a command-line experience for managing Azure resources. It's a great tool for building custom automation to use Azure resources. This article explains how to restore an entire file share or specific files from a restore point created by Azure Backup by using the Azure CLI. You can also perform these steps with Azure PowerShell or in the Azure portal.

By the end of this article, you'll learn how to perform the following operations with the Azure CLI:

• View restore points for a backed-up Azure file share.
• Restore a full Azure file share.
• Restore individual files or folders.

Note

Azure Backup now supports restoring multiple files or folders to the original or an alternate location using Azure CLI. Refer to the Restore multiple files or folders to original or alternate location section of this document to learn more.

Prerequisites

This article assumes that you already have an Azure file share that's backed up by Azure Backup. If you don't have one, see Back up Azure file shares with the CLI to configure backup for your file share. For this article, you use the following resources:

File share	Storage account	Region	Details
azurefiles	afsaccount	EastUS	Original source backed up by using Azure Backup
azurefiles1	afaccount1	EastUS	Destination source used for alternate location recovery

You can use a similar structure for your file shares to try out the different types of restores explained in this article.

Prepare your environment for the Azure CLI

• Use the Bash environment in Azure Cloud Shell. For more information, see Quickstart for Bash in Azure Cloud Shell.

  

• If you prefer to run CLI reference commands locally, install the Azure CLI. If you're running on Windows or macOS, consider running Azure CLI in a Docker container. For more information, see How to run the Azure CLI in a Docker container.

  • If you're using a local installation, sign in to the Azure CLI by using the az login command. To finish the authentication process, follow the steps displayed in your terminal. For other sign-in options, see Sign in with the Azure CLI.

  • When you're prompted, install the Azure CLI extension on first use. For more information about extensions, see Use extensions with the Azure CLI.

  • Run az version to find the version and dependent libraries that are installed. To upgrade to the latest version, run az upgrade.

• This tutorial requires version 2.0.18 or later of the Azure CLI. If using Azure Cloud Shell, the latest version is already installed.

Fetch recovery points for the Azure file share

Use the az backup recoverypoint list cmdlet to list all recovery points for the backed-up file share.

The following example fetches the list of recovery points for the azurefiles file share in the afsaccount storage account.

az backup recoverypoint list --vault-name azurefilesvault --resource-group azurefiles --container-name "StorageContainer;Storage;AzureFiles;afsaccount" --backup-management-type azurestorage --item-name "AzureFileShare;azurefiles" --workload-type azurefileshare --out table

You can also run the previous cmdlet by using the friendly name for the container and the item by providing the following two additional parameters:

• --backup-management-type: azurestorage
• --workload-type: azurefileshare

az backup recoverypoint list --vault-name azurefilesvault --resource-group azurefiles --container-name afsaccount --backup-management-type azurestorage --item-name azurefiles --workload-type azurefileshare --out table

The result set is a list of recovery points with time and consistency details for each restore point.

Name                Time                        Consistency
------------------  -------------------------   --------------------
932887541532871865  2020-01-05T07:08:23+00:00   FileSystemConsistent
932885927361238054  2020-01-05T07:08:10+00:00   FileSystemConsistent
932879614553967772  2020-01-04T21:33:04+00:00   FileSystemConsistent

The Name attribute in the output corresponds to the recovery point name that can be used as a value for the --rp-name parameter in recovery operations.

Full share recovery by using the Azure CLI

You can use this restore option to restore the complete file share in the original or an alternate location.

Define the following parameters to perform restore operations:

• --container-name: The name of the storage account that hosts the backed-up original file share. To retrieve the name or friendly name of your container, use the az backup container list command.
• --item-name: The name of the backed-up original file share you want to use for the restore operation. To retrieve the name or friendly name of your backed-up item, use the az backup item list command.

Restore a full share to the original location

When you restore to an original location, you don't need to specify target-related parameters. Only Resolve Conflict must be provided.

The following example uses the az backup restore restore-azurefileshare cmdlet with restore mode set to originallocation to restore the azurefiles file share in the original location. You use the recovery point 932883129628959823, which you obtained in Fetch recovery points for the Azure file share:

az backup restore restore-azurefileshare --vault-name azurefilesvault --resource-group azurefiles --rp-name 932887541532871865   --container-name "StorageContainer;Storage;AzureFiles;afsaccount" --item-name "AzureFileShare;azurefiles" --restore-mode originallocation --resolve-conflict overwrite --out table

Name                                  ResourceGroup
------------------------------------  ---------------
6a27cc23-9283-4310-9c27-dcfb81b7b4bb  azurefiles

The Name attribute in the output corresponds to the name of the job that's created by the backup service for your restore operation. To track the status of the job, use the az backup job show cmdlet.

Restore a full share to an alternate location

You can use this option to restore a file share to an alternate location and keep the original file share as is. Specify the following parameters for alternate location recovery:

• --target-storage-account: The storage account to which the backed-up content is restored. The target storage account must be in the same location as the vault.
• --target-file-share: The file share within the target storage account to which the backed-up content is restored.
• --target-folder: The folder under the file share to which data is restored. If the backed-up content is to be restored to a root folder, give the target folder values as an empty string.
• --resolve-conflict: Instruction if there's a conflict with the restored data. Accepts Overwrite or Skip.

The following example uses az backup restore restore-azurefileshare with restore mode as alternatelocation to restore the azurefiles file share in the afsaccount storage account to the azurefiles1" file share in the afaccount1 storage account.

az backup restore restore-azurefileshare --vault-name azurefilesvault --resource-group azurefiles --rp-name 932883129628959823 --container-name "StorageContainer;Storage;AzureFiles;afsaccount" --item-name "AzureFileShare;azurefiles" --restore-mode alternatelocation --target-storage-account afaccount1 --target-file-share azurefiles1 --target-folder restoredata --resolve-conflict overwrite --out table

Name                                  ResourceGroup
------------------------------------  ---------------
babeb61c-d73d-4b91-9830-b8bfa83c349a  azurefiles

The Name attribute in the output corresponds to the name of the job that's created by the backup service for your restore operation. To track the status of the job, use the az backup job show cmdlet.

Item-level recovery

You can use this restore option to restore individual files or folders in the original or an alternate location.

Define the following parameters to perform restore operations:

• --container-name: The name of the storage account that hosts the backed-up original file share. To retrieve the name or friendly name of your container, use the az backup container list command.
• --item-name: The name of the backed-up original file share you want to use for the restore operation. To retrieve the name or friendly name of your backed-up item, use the az backup item list command.

Specify the following parameters for the items you want to recover:

• SourceFilePath: The absolute path of the file, to be restored within the file share, as a string. This path is the same path used in the az storage file download or az storage file show CLI commands.
• SourceFileType: Choose whether a directory or a file is selected. Accepts Directory or File.
• ResolveConflict: Instruction if there's a conflict with the restored data. Accepts Overwrite or Skip.

Restore individual files or folders to the original location

Use the az backup restore restore-azurefiles cmdlet with restore mode set to originallocation to restore specific files or folders to their original location.

The following example restores the RestoreTest.txt file in its original location: the azurefiles file share.

az backup restore restore-azurefiles --vault-name azurefilesvault --resource-group azurefiles --rp-name 932881556234035474 --container-name "StorageContainer;Storage;AzureFiles;afsaccount" --item-name "AzureFileShare;azurefiles" --restore-mode originallocation  --source-file-type file --source-file-path "Restore/RestoreTest.txt" --resolve-conflict overwrite  --out table

Name                                  ResourceGroup
------------------------------------  ---------------
df4d9024-0dcb-4edc-bf8c-0a3d18a25319  azurefiles

The Name attribute in the output corresponds to the name of the job that's created by the backup service for your restore operation. To track the status of the job, use the az backup job show cmdlet.

Restore individual files or folders to an alternate location

To restore specific files or folders to an alternate location, use the az backup restore restore-azurefiles cmdlet with restore mode set to alternatelocation and specify the following target-related parameters:

• --target-storage-account: The storage account to which the backed-up content is restored. The target storage account must be in the same location as the vault.
• --target-file-share: The file share within the target storage account to which the backed-up content is restored.
• --target-folder: The folder under the file share to which data is restored. If the backed-up content is to be restored to a root folder, give the target folder's value as an empty string.

The following example restores the RestoreTest.txt file originally present in the azurefiles file share to an alternate location: the restoredata folder in the azurefiles1 file share hosted in the afaccount1 storage account.

az backup restore restore-azurefiles --vault-name azurefilesvault --resource-group azurefiles --rp-name 932881556234035474 --container-name "StorageContainer;Storage;AzureFiles;afsaccount" --item-name "AzureFileShare;azurefiles" --restore-mode alternatelocation --target-storage-account afaccount1 --target-file-share azurefiles1 --target-folder restoredata --resolve-conflict overwrite --source-file-type file --source-file-path "Restore/RestoreTest.txt" --out table

Name                                  ResourceGroup
------------------------------------  ---------------
df4d9024-0dcb-4edc-bf8c-0a3d18a25319  azurefiles

The Name attribute in the output corresponds to the name of the job that's created by the backup service for your restore operation. To track the status of the job, use the az backup job show cmdlet.

Restore multiple files or folders to original or alternate location

To perform restore for multiple items, pass the value for the source-file-path parameter as space separated paths of all files or folders you want to restore.

The following example restores the Restore.txt and AFS testing Report.docx files in their original location.

az backup restore restore-azurefiles --vault-name azurefilesvault --resource-group azurefiles --rp-name 932889937058317910 --container-name "StorageContainer;Storage;AzureFiles;afsaccount" --item-name "AzureFileShare;azurefiles" --restore-mode originallocation  --source-file-type file --source-file-path "Restore Test.txt" "AFS Testing Report.docx" --resolve-conflict overwrite  --out table

The output will be similar to the following:

Name                                          ResourceGroup
------------------------------------          ---------------
649b0c14-4a94-4945-995a-19e2aace0305          azurefiles

The Name attribute in the output corresponds to the name of the job that's created by the backup service for your restore operation. To track the status of the job, use the az backup job show cmdlet.

If you want to restore multiple items to an alternate location, use the command above by specifying target-related parameters as explained in the Restore individual files or folders to an alternate location section.
