Back up files and applications on Azure Stack

You can use Azure Backup to protect (or back up) files and applications on Azure Stack. To back up files and applications, install Microsoft Azure Backup Server as a virtual machine running on Azure Stack. You can protect the files on any Azure Stack server in the same virtual network. Once you've installed Azure Backup Server, add Azure disks to increase the local storage available for short-term backup data. Azure Backup Server uses Azure storage for long-term retention.

Note

Though Azure Backup Server and System Center Data Protection Manager (DPM) are similar, DPM isn't supported for use with Azure Stack.

This article doesn't cover installing Azure Backup Server in the Azure Stack environment. To install Azure Backup Server on Azure Stack, see the article, Installing Azure Backup Server.

Back up Files and Folders in Azure Stack VMs to Azure

To configure Azure Backup Server to protect Files in Azure Stack virtual machines, open the Azure Backup Server console. You'll use the console to configure protection groups and to protect the data on your virtual machines.

  1. In the Azure Backup Server console, select Protection and in the toolbar, select New to open the Create New Protection Group wizard.

    Configure protection in Azure Backup Server console

    It may take a few seconds for the wizard to open. Once the wizard opens, select Next to advance to the Select Protection Group Type screen.

    New Protection group wizard opens

  2. On the Select Protection Group Type screen, choose Servers and select Next.

    Select Protection Group Type

    The Select Group Members screen opens.

    Select Group Members

  3. In the Select Group Members screen, select + to expand the list of subitems. For all items that you want to protect, select the check box. Once all items have been selected, select Next.

    Select each item you want to protect

    Microsoft recommends putting all data that will share a protection policy, into one protection group. For complete information about planning and deploying protection groups, see the System Center DPM article, Deploy Protection Groups.

  4. In the Select Data Protection Method screen, type a name for the protection group. Select the checkbox for I want short-term protection using: and I want online protection. Select Next.

    Select Data Protection Method

    To select I want online protection, you must first select I want short-term protection using: Disk. Azure Backup Server doesn't protect to tape, so disk is the only choice for short-term protection.

  5. In the Specify Short-Term Goals screen, choose how long to retain the recovery points saved to disk, and when to save incremental backups. Select Next.

    Important

    You should not retain operational recovery (backup) data on Azure Backup Server-attached disks for more than five days.

    Specify Short-Term Goals

    Instead of selecting an interval for incremental backups, to run an express full backup just before each scheduled recovery point, select Just before a recovery point. If you're protecting application workloads, Azure Backup Server creates recovery points per the Synchronization frequency schedule (provided the application supports incremental backups). If the application doesn't support incremental backups, Azure Backup Server runs an express full backup.

    For File recovery points, specify when to create recovery points. Select Modify to set the times and days of the week when recovery points are created.

  6. In the Review disk allocation screen, review the storage pool disk space allocated for the protection group.

    Total Data size is the size of the data you want to back up and Disk space to be provisioned on Azure Backup Server is the recommended space for the protection group. Azure Backup Server chooses the ideal backup volume, based on the settings. However, you can edit the backup volume choices in the Disk allocation details. For the workloads, select the preferred storage in the dropdown menu. Your edits change the values for Total Storage and Free Storage in the Available Disk Storage pane. Underprovisioned space is the amount of storage Azure Backup Server suggests you add to the volume, to continue with backups smoothly in the future.

  7. In Choose replica creation method, select how you want to handle the initial full data replication. If you decide to replicate over the network, Azure recommends you choose an off-peak time. For large amounts of data or less than optimal network conditions, consider replicating the data using removable media.

  8. In Choose consistency check options, select how you want to automate consistency checks. Enable consistency checks to run only when data replication becomes inconsistent, or according to a schedule. If you don't want to configure automatic consistency checking, run a manual check at any time by:

    • In the Protection area of the Azure Backup Server console, right-click the protection group and select Perform Consistency Check.
  9. If you choose to back up to Azure, on the Specify online protection data page make sure the workloads you want to back up to Azure are selected.

  10. In Specify online backup schedule, specify when incremental backups to Azure should occur.

    You can schedule backups to run every day/week/month/year and the time/date at which they should run. Backups can occur up to twice a day. Each time a backup job runs, a data recovery point is created in Azure from the copy of the backed-up data stored on the Azure Backup Server disk.

  11. In Specify online retention policy, specify how the recovery points created from the daily/weekly/monthly/yearly backups are retained in Azure.

  12. In Choose online replication, specify how the initial full replication of data occurs.

  13. On Summary, review your settings. When you select Create Group, the initial data replication occurs. When the data replication finishes, on the Status page, the protection group status shows as OK. The initial backup job takes place in line with the protection group settings.

Recover file data

Use Azure Backup Server console to recover data to your virtual machine.

  1. In the Azure Backup Server console, on the navigation bar, select Recovery and browse for the data you want to recover. In the results pane, select the data.

  2. On the calendar in the recovery points section, dates in bold indicate recovery points are available. Select the date to recover.

  3. In the Recoverable item pane, select the item you want to recover.

  4. In the Actions pane, select Recover to open the Recovery Wizard.

  5. You can recover data as follows:

    • Recover to the original location - If the client computer is connected over VPN, this option doesn't work. Instead use an alternate location, and then copy data from that location.
    • Recover to an alternate location
  6. Specify the recovery options:

    • For Existing version recovery behavior, select Create copy, Skip, or Overwrite. Overwrite is available only when recovering to the original location.
    • For Restore security, choose Apply settings of the destination computer or Apply the security settings of the recovery point version.
    • For Network bandwidth usage throttling, select Modify to enable network bandwidth usage throttling.
    • Notification Select Send an e-mail when the recovery completes, and specify the recipients who will receive the notification. Separate the e-mail addresses with commas.
    • After making the selections, select Next
  7. Review your recovery settings, and select Recover.

    Note

    While the recovery job is in progress, all synchronization jobs for the selected recovery items are canceled.

If you're using Modern Backup Storage (MBS), File Server end-user recovery (EUR) isn't supported. File Server EUR has a dependency on Volume Shadow Copy Service (VSS), which Modern Backup Storage doesn't use. If EUR is enabled, use the following steps to recover data:

  1. Navigate to the protected files, and right-click the file name and select Properties.

  2. On the Properties menu, select Previous Versions and choose the version you want to recover.

View Azure Backup Server with a vault

To view Azure Backup Server entities in the Azure portal, you can follow the following steps:

  1. Open Recovery Services vault.
  2. Select Backup Infrastructure.
  3. View Backup Management Servers.
