New features in DPM 2016
The following features are either new to DPM or are improved for DPM 2016.
Modern Backup Storage - Using Resilient File System (ReFS) block-cloning technology to store incremental backups, DPM 2016 improves storage utilization and performance. Backup storage grows and shrinks with production data source. There's no over-allocation of storage.
Resilient change tracking (RCT) - DPM uses RCT (the native change tracking in Hyper-V), which removes the need for time-consuming consistency checks. RCT provides better resiliency than the change tracking provided by VSS snapshot-based backups. DPM also uses RCT for incremental backup. It identifies VHD changes for virtual machines and transfers only those blocks that are indicated by the change tracker.
Continued protection during cluster aware updates - Windows Server 2016 comes with the cluster OS rolling update, where a cluster can be upgraded to Windows Server 2016 without bringing it down. DPM 2016 continues to protect VMs during the upgrade, maintaining the backup service-level agreement (SLA).
Shielded VM Backups - Shielded VMs in Windows Server 2016 help protect sensitive VMs from inspection, tampering, and data theft by malware and malicious administrators. DPM 2016 backups retain the protections provided by shielded VMs to ensure they can be recovered seamlessly and securely.
Hyper-V with Storage Spaces Direct - DPM recognizes and protects Hyper-V VMs deployed on Storage Spaces Direct, delivering seamless backup and recovery of VMs in disaggregated and hyper-converged scenarios.
Hyper-V with ReFS SOFS Cluster - DPM 2016 can back up Hyper-V VMs deployed on ReFS-based SOFS clusters. Backup and recovery of RCT-based VMs and non-RCT VMs is supported.
Upgrading a DPM production server to 2016 doesn't require a reboot - When you upgrade to DPM 2016, you aren't required to reboot the production server. To avoid rebooting the production server, upgrade to DPM 2016 and upgrade the DPM agent on the production servers. Backups continue and you reboot the production server when you want.
Modern Backup Storage
Modern Backup Storage is a feature that provides several benefits including:
Improved storage savings
Modern Backup Storage achieves 30-40% storage savings using technologies such as Resilient File System (ReFS). Using ReFS volumes and storing backups on VHDXs means there are no Local Disk Manager (LDM) limits or storage over-allocations. DPM storage consumption is flexible: it grows and shrinks based on the production data source’s storage changes.
Faster backups
DPM 2016 uses block cloning to store backups on ReFS volumes. Instead of using copy-on-write to store backups (which was used by VolSnap in DPM 2012 R2), DPM 2016's block cloning uses allocate-on-write. This change improves IOPS efficiency, making backups nearly 70% faster.
Choose the volumes for your data source to increase storage efficiency
DPM's workload-aware storage feature decreases costs by providing flexible storage choices for a given data source. This means DPM can use expensive, high-performance disks for backing up high-IOPS workloads, such as SQL or SharePoint. Low-performance storage can be used for reduced-IOPS workloads.
Back up storage consumption in line with production data source
Without Logical Disk Manager (LDM) limits, data sources grow and shrink as needed, without the need for manual intervention. DPM doesn't need to allocate storage to data sources beforehand and can dynamically allow the backups to adjust as needed, thus achieving higher efficiency with less storage requirement.
Hyper-V protection improvements
The following information touches on the improvements for protecting VMs with DPM 2016.
Resilient Change Tracking (RCT)
In Windows Server 2016, Hyper-V virtual hard disks have built-in change tracking. As a result, in case of a host outage or VM migration, change-tracking is automatically preserved. With RCT, backups:
- are more reliable: Consistency checks aren't required after VM migration.
- are scalable: More parallel backups and less storage overhead.
- have improved performance: Lower impact on the production fabric and faster backup.
Enabling RCT VM backup
Hyper-V VMs deployed on Windows Server 2016 and protected using DPM 2016 have RCT by default. VMs deployed on Windows Server 2012 R2 or earlier don't support RCT. However, you can upgrade older VMs. To upgrade older VMs to enable RCT:
In Hyper-V Manager, shut down the virtual machine.
In Hyper-V Manager, select Action > Upgrade Configuration Version.
If this option isn't available for the virtual machine, then it's already at the highest configuration version supported by the Hyper-V host. For more information about checking or upgrading the virtual machine configuration version, see the article, upgrading virtual machine version to Windows Server 2016.
If you want to use Windows PowerShell to upgrade the virtual machine configuration, run the following command where vmname is the name of the virtual machine.
Update-VMVersion <vmname>On the DPM 2016 server:
- Stop protection of the VM and select Retain Data.
- In the DPM 2016 Administrator Console, select Protection > on the tool ribbon, select New to start the Create Protection Wizard. Go through the wizard and select Refresh to update the data sources.
- Select your VM and create a new protection group.
- Delete the old VM's retained data once the retention range has expired.
This backs up RCT-enabled VMs deployed in various configurations. The following sections describe the supported scenarios:
Meet backup SLA during cluster operating system rolling upgrade
Cluster OS rolling upgrade is a feature of Windows Server 2016 used to upgrade the cluster nodes' operating system, from Windows Server 2012 R2 to Windows Server 2016, without stopping the Hyper-V or Scale-Out File Server (SOFS) workloads. Cluster OS rolling upgrade ensures protection isn't interrupted during operating system upgrades. This sustained protection meets the backup SLA, reinforces continuity, and provides peace of mind for backup administrators. For detailed information on the cluster OS rolling upgrade process, see the article, Cluster OS Rolling Upgrade Process.
To enable uninterrupted protection, run the following steps for each node:
Drain Roles on the node.
This puts the node in a paused state and automatically migrates any VM on that node to another cluster node.
Restart the node.
Evict the node.
Install Windows Server 2016.
Install the DPM agent.
Add the node back to the cluster.
This allows backups to occur without consistency checks while keeping the cluster alive.
Seamless protection and recovery of Shielded VMs (vTPM-enabled VMs)
Trusted Platform Module (TPM) is a chip in the motherboard of a computer that helps to integrate cryptographic keys. These keys are used by BitLocker to protect the computer even if it's stolen. Virtual TPM (vTPM) is a feature in Windows Server 2016. With vTPM, you can use BitLocker and a virtual TPM chip to encrypt a VM, thereby protecting the VM. These VMs, called Shielded VMs, can only be run on healthy and approved hosts in the fabric.
DPM 2016 supports the backup and recovery of Shielded VMs that have their VHDs/VHDXs protected with vTPM. Note that Item Level Recovery (ILR) and Alternate Location Recovery (ALR) to a location outside the guarded fabric isn't available for this scenario.
Protecting VMs stored on Storage Spaces Direct
Storage Spaces Direct leverages the Storage Spaces feature introduced in Windows Server 2012 R2, which allows you to deploy highly available (HA) storage systems using local storage. Storage Spaces Direct leverages the local disks on hosts to provide a shared pool of clustered storage that can be used as primary storage for Hyper-V virtual machine files or for secondary storage for Hyper-V Replica virtual machine files. The primary use case for Storage Spaces Direct is private cloud storage, either on-premises for enterprises or in hosted private clouds for service providers. For more information about Storage Spaces Direct, see the article Storage Spaces Direct in Windows Server 2016.
DPM protects Hyper-V VMs that use Storage Spaces Direct. Most configurations are supported, including the backup of VMs using the Storage Spaces Direct hyper-converged scenario with the Hyper-V (compute) and Storage Spaces Direct (storage) components on the same cluster. Note that backing up and restoring virtual machines running on a Windows Nano Server isn't supported.
Protecting VMs stored on NTFS and ReFS-based SOFS clusters
DPM 2016 can back up VMs deployed on both NTFS and ReFS-based SOFS clusters.
To protect VMs on SOFS clusters, add the following machine accounts to the backup operator groups and share permissions:
- If protecting a highly available (HA) VM, provide the machine account name of the host cluster and cluster nodes and the DPM server.
- If protecting a non-HA VM, provide the machine name of the Hyper-V host and the DPM server.
To add the machine accounts to the backup operator groups, run the following steps for each node in the SOFS cluster:
Open the command prompt, and type lusrmgr.msc to open Local Users and Groups.
In the Local Users and Groups dialog, select Groups.
In the list of groups, right-click Backup Operators and select Properties.
The Backup Operators Properties dialog opens.
In the Backup Operators Properties dialog, select Add.
In the Select Users, Computers, Services Accounts, or Groups dialog, select Object Types. The Object Types dialog opens.
In the Object Types dialog, select Computers and select OK. The Object Types dialog closes.
In the Select Users, Computers, Service Accounts, or Groups dialog, enter the name of the server or cluster and select Check Names.
Once you've identified the computers, restart the node.
To give permissions to the share
On a server where the SOFS/SMB share is hosted, open Server Manager > File and Storage Services > Shares.
Right-click the VM storage share and then select Properties.
In the Properties dialog, on the left navigation menu, select Permissions.
Select Customize permissions to open the Advanced Security Settings dialog.
On the Permissions tab, select Add.
Select Select a Principal.
In the Select User, Computer, Services Account, or Group dialog, select Object Types.
In the Object Types dialog, select Computers and select OK.
In the Select User, Computer, Service Account, or Group dialog, enter the name of the Hyper-V node or cluster name you want to have permission for.
Select Check Names to resolve the name and select OK.
In the Permission Entry for Share dialog, select Full Control and select OK.
In the Advanced Security Settings for Share dialog, select the Share tab and repeat steps 6-11 for the Share tab instead of the Permissions tab.
When you've finished adding permissions for the servers, select Apply.
This prepares the VMs on SOFS shares for the backup process.
New features in DPM 2016 UR10 Hotfix
DPM 2016 UR10 Hotfix contains the enhancement below to improve backup times. For more information and the installation instructions, see the KB article.
Removed File Catalog dependency for online backup of file/folder workloads
This update rollup hotfix removes the dependency on File Catalog (list of files in a recovery point, maintained in the cloud), which was needed to restore individual files and folders from the Online recovery points. With this hotfix, DPM 2016 now uses a modern iSCSI mount method to provide individual file restoration.
The new method has the following advantages:
Reduces backup time up to 15% since file catalog metadata (list of files in a recovery point) isn't generated during backup.
Item level recovery errors due to inconsistent file catalog metadata is avoided, since iSCSI mounts are used.
After the recovery point is mounted, file browsing during item level recovery is faster for recovery points with many files and folders.
We recommended you to update your DPM 2016 installation to Hotfix for Update Rollup 10 to benefit from the enhancement. Ensure that you also update your MARS Agent to the latest version (2.0.9262.0 or later).
