Restore Azure Data Lake Storage using Azure portal (preview)

This article describes how to restore Azure Data Lake Storage vaulted backups (preview) using Azure portal.

Prerequisites

Before you restore Azure Data Lake Storage, ensure the following prerequisites are met:

  • The Backup vault must have the Storage account backup contributor role assigned to the target storage account to which the backup data needs to be restored.
  • Cool and cold tier blobs are restored in hot tier.
  • The target storage account selected for restore must not have any container with same name.
  • The target storage account must be in same ___location as source storage account and vault.

Note

Vaulted backups only support restoring data to another storage account, which is different from the one that was backed up.

  6. On the Restore destination pane, under Select option to restore the blobs, select one of these options:

    • Restore all backed-up containers: This option restores all backed-up containers in the storage account. Select the Target subscription in which the target storage account is present, and then select Target storage account where the data needs to be restored.

    • Browse and select containers to restore: This option allows you to browse and select up to 100 containers to restore. (Optional) Specify a set of prefixes to restore specific blobs within a container. To provide the list of prefixes, select Add/Edit containers corresponding to each container that you select for restore.

    Note

    You must have the required permission to view the containers in the storage account; otherwise, the contents of the storage account don't appear.

  7. On the Restore parameters tab, select Validate to ensure that the required permissions to perform the restore are assigned to the backed-up storage accounts with Data Lake selections.

    If the validation fails, select Assign missing roles to grant permissions. See the prerequisites for the required roles.

  8. After the validation succeeds, select Review + restore and restore the backups to the selected Data Lake Storage.

  9. On the Review + restore tab, select Restore to start the restore operation.

You can track the progress of restore under Backup Jobs.
