Backup VMware Server Workloads to Azure Backup Server

In my previous article, I explained how to install and configure Azure Backup Server. This article explains how to configure Azure Backup Server to help protect VMware  Server workloads. I am assuming that you already have Azure Backup Server installed. Azure Backup Server can back up, or help protect, VMware vCenter Server version 5.5 and later version.

 

 

 

 

 

 

Step1: Create a secure connection to the vCenter Server

By default, Azure Backup Server communicates with each vCenter Server via an HTTPS channel. To turn on the secure communication, we recommend that you install the VMware Certificate Authority (CA) certificate on Azure Backup Server.

To fix this issue, and create a secure connection, download the trusted root CA certificates.

  1. In the browser on Azure Backup Server, enter the URL to the vSphere Web Client. The vSphere Web Client login page appears. Example, https://vcenter.domain.com

At the bottom of the information for administrators and developers, locate the Download trusted root CA certificates link.

  1. Click Download trusted root CA certificates.

The vCenter Server downloads a file to your local computer. The file’s name is named download. Depending on your browser, you receive a message that asks whether to open or save the file.

  1. Save the file to a location on Azure Backup Server. When you save the file, add the .zip file name extension. The file is a .zip file that contains the information about the certificates. With the .zip extension, you can use the extraction tools.
  2. Right-click zip, and then select Extract Allto extract the contents. The CRL file has an extension that begins with a sequence like .r0 or .r1. The CRL file is associated with a certificate.
  3. In the certsfolder, right-click the root certificate file, and then click Rename. Change the root certificate’s extension to .crt. When you’re asked if you’re sure you want to change the extension, click Yes or OK.  Right-click the root certificate and from the pop-up menu, select Install Certificate. The Certificate Import Wizard dialog box appears.
  4. In the Certificate Import Wizarddialog box, select Local Machine as the destination for the certificate, and then click Next to continue.

If you’re asked if you want to allow changes to the computer, click Yes or OK, to all the changes.

  1. On the Certificate Storepage, select Place all certificates in the following store, and then click Browse to choose the certificate store.

The Select Certificate Store dialog box appears.

  1. Select Trusted Root Certification Authoritiesas the destination folder for the certificates, and then click OK. The Trusted Root Certification Authorities folder is confirmed as the certificate store. Click Next.
  2. On the Completing the Certificate Import Wizardpage, verify that the certificate is in the desired folder, and then click Finish.
  3. Sign in to the vCenter Server to confirm that your connection is secure.

If you have secure boundaries within your organization, and don’t want to turn on the HTTPS protocol, use the following procedure to disable the secure communications.

Step2: Disable secure communication protocol

If your organization doesn’t require the HTTPS protocol, use the following steps to disable HTTPS. To disable the default behavior, create a registry key that ignores the default behavior.

  1. Copy and paste the following text into a .txt file.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Data Protection Manager\VMWare]

“IgnoreCertificateValidation”=dword:00000001

  1. Save the file to your Azure Backup Server computer. For the file name, use DisableSecureAuthentication.reg.
  2. Double-click the file to activate the registry entry.

Step3: Create a role and user account on the vCenter Server

To establish the necessary user credentials to back up the vCenter Server workloads, create a role with specific privileges, and then associate the user account with the role.

Azure Backup Server uses a username and password to authenticate with the vCenter Server. Azure Backup Server uses these credentials as authentication for all backup operations.

To add a vCenter Server role and its privileges for a backup administrator:

  1. Sign in to the vCenter Server, and then in the vCenter Server Navigatorpanel, click Administration.
  2. In Administrationselect Roles, and then in the Roles panel click the add role icon (the + symbol). The Create Role dialog box appears.
  3. In the Create Roledialog box, in the Role name box, enter BackupAdminRole. The role name can be whatever you like, but it should be recognizable for the role’s purpose.
  4. Select the privileges for the appropriate version of vCenter, and then click OK. The following table identifies the required privileges for vCenter 6.0 and vCenter 5.5.

When you select the privileges, click the icon next to the parent label to expand the parent and view the child privileges. To select the VirtualMachine privileges, you need to go several levels into the parent child hierarchy. You don’t need to select all child privileges within a parent privilege. After you click OK, the new role appears in the list on the Roles panel.

Privileges for vCenter 6.0 Privileges for vCenter 5.5

VirtualMachine.Provisioning.DiskRandomAccess
VirtualMachine.Provisioning.DiskRandomRead VirtualMachine.Provisioning.DiskRandomRead
VirtualMachine.State.CreateSnapshot VirtualMachine.State.CreateSnapshot
VirtualMachine.State.RemoveSnapshot VirtualMachine.State.RemoveSnapshot

Step4: Create a vCenter Server user account and permissions

After the role with privileges is set up, create a user account. The user account has a name and password, which provides the credentials that are used for authentication.

  1. To create a user account, in the vCenter Server Navigatorpanel, click Users and Groups. The vCenter Users and Groups panel appears.
  2. In the vCenter Users and Groupspanel, select the Users tab, and then click the add users icon (the + symbol). The New User dialog box appears.
  3. In the New Userdialog box, add the user’s information and then click OK. In this procedure, the username is BackupAdmin. The new user account appears in the list.
  4. To associate the user account with the role, in the Navigatorpanel, click Global Permissions. In the Global Permissions panel, select the Manage tab, and then click the add icon (the + symbol). The Global Permissions Root – Add Permission dialog box appears.
  5. In the Global Permission Root – Add Permissiondialog box, click Add to choose the user or group.  The Select Users/Groups dialog box appears.
  6. In the Select Users/Groupsdialog box, choose BackupAdmin and then click Add. In Users, the domain\username format is used for the user account. If you want to use a different domain, choose it from the Domain Click OK to add the selected users to the Add Permission dialog box.
  7. Now that you’ve identified the user, assign the user to the role. In Assigned Role, from the drop-down list, select BackupAdminRole, and then click OK. On the Managetab in the Global Permissions panel, the new user account and the associated role appear in the list.

Step6: Establish vCenter Server credentials on Azure Backup Server

  1. To open Azure Backup Server, double-click the icon on the Azure Backup Server desktop.
  2. In the Azure Backup Server console, click Management, click Production Servers, and then on the tool ribbon, click Manage VMware. The Manage Credentialsdialog box appears.
  3. In the Manage Credentialsdialog box, click Add to open the Add Credential dialog box.
  4. In the Add Credentialdialog box, enter a name and a description for the new credential. Then specify the username and password. The name, Contoso Vcenter credential is used to identify the credential in the next procedure. Use the same username and password that is used for the vCenter Server. If the vCenter Server and Azure Backup Server are not in the same domain, in User name, specify the domain.

Click Add to add the new credential to Azure Backup Server. The new credential appears in the list in the Manage Credentials dialog box.

  1. To close the Manage Credentialsdialog box, click the X in the upper-right corner.

Step7: Add the vCenter Server to Azure Backup Server

Production Server Addition Wizard is used to add the vCenter Server to Azure Backup Server. To open Production Server Addition Wizard, complete the following procedure:

  1. In the Azure Backup Server console, click Management, click Production Servers, and then click Add. The Production Server Addition Wizarddialog box appears.
  2. On the Select Production Server typepage, select VMware Servers, and then click Next.
  3. In Server Name/IP Address, specify the fully qualified domain name (FQDN) or IP address of the VMware server. If all the ESXi servers are managed by the same vCenter, you can use the vCenter name.
  4. In SSL Port, enter the port that is used to communicate with the VMware server. Use port 443, which is the default port, unless you know that a different port is required.
  5. In Specify Credential, select the credential that you created earlier.
  6. Click Addto add the VMware server to the list of Added VMware Servers, and then click Next to move to the next page in the wizard.
  7. In the Summarypage, click Add to add the specified VMware server to Azure Backup Server. The VMware server backup is an agentless backup, and the new server is added immediately. The Finishpage shows you the results.

After you add the vCenter Server to Azure Backup Server, the next step is to create a protection group. The protection group specifies the various details for short or long-term retention, and it is where you define and apply the backup policy. The backup policy is the schedule for when backups occur, and what is backed up.

Step8: Configure a protection group

After you check that you have proper storage, use the Create New Protection Group wizard to add VMware virtual machines.

  1. In the Azure Backup Server console, click Protection, and in the tool ribbon, click Newto open the Create New Protection Group wizard.

The Create New Protection Group wizard dialog box appears. Click Next to advance to the Select protection group type page.

  1. On the Select Protection group typepage, select Servers and then click Next. The Select group memberspage appears.
  2. On the Select group memberspage, the available members and the selected members appear. Select the members that you want to protect, and then click Next.

When you select a member, if you select a folder that contains other folders or VMs, those folders and VMs are also selected. The inclusion of the folders and VMs in the parent folder is called folder-level protection. To remove a folder or VM, clear the check box.

  1. On the Select Data Protection Methodpage, enter a name for the protection group. Short-term protection (to disk) and online protection are selected. If you want to use online protection (to Azure), you must use short-term protection to disk. Click Next to proceed to the short-term protection range.
  2. On the Specify Short-Term Goalspage, for Retention Range, specify the number of days that you want to retain recovery points that are stored to disk. If you want to change the time and days when recovery points are taken, click Modify. The short-term recovery points are full backups. They are not incremental backups. When you are satisfied with the short-term goals, click Next.
  3. On the Review Disk Allocationpage, review and if necessary, modify the disk space for the VMs. The recommended disk allocations are based on the retention range that is specified in the Specify Short-Term Goals page, the type of workload, and the size of the protected data (identified in step 3).
    • Data size:Size of the data in the protection group.
    • Disk space:The recommended amount of disk space for the protection group. If you want to modify this setting, you should allocate total space that is slightly larger than the amount that you estimate each data source grows.
    • Colocate data:If you turn on colocation, multiple data sources in the protection can map to a single replica and recovery point volume. Colocation isn’t supported for all workloads.
    • Automatically grow:If you turn on this setting, if data in the protected group outgrows the initial allocation, System Center Data Protection Manager tries to increase the disk size by 25 percent.
    • Storage pool details:Shows the status of the storage pool, including total and remaining disk size.

When you are satisfied with the space allocation, click Next.

  1. On the Choose Replica Creation Methodpage, specify how you want to generate the initial copy, or replica, of the protected data on Azure Backup Server.

The default is Automatically over the network and Now. If you use the default, we recommend that you specify an off-peak time. Choose Later and specify a day and time.  For large amounts of data or less-than-optimal network conditions, consider replicating the data offline by using removable media. After you have made your choices, click Next.

  1. On the Consistency Check Optionspage, select how and when to automate the consistency checks. You can run consistency checks when replica data becomes inconsistent, or on a set schedule. If you don’t want to configure automatic consistency checks, you can run a manual check. In the protection area of the Azure Backup Server console, right-click the protection group and then select Perform Consistency Check. Click Next to move to the next page.
  2. On the Specify Online Protection Datapage, select one or more data sources that you want to protect. You can select the members individually, or click Select All to choose all members. After you choose the members, click Next.
  3. On the Specify Online Backup Schedulepage, specify the schedule to generate recovery points from the disk backup. After the recovery point is generated, it is transferred to the Recovery Services vault in Azure. When you are satisfied with the online backup schedule, click Next.
  4. On the Specify Online Retention Policypage, indicate how long you want to retain the backup data in Azure. After the policy is defined, click Next.
  5. On the Summarypage, review the details for your protection group members and settings, and then click Create Group.

Now you are ready to backup VMware VM using Backup Server v2.

Step9: Create a Storage Pool for Azure Backup Server

  1. Navigating to the Storage Pools page in Server Manager
  2. Launch Server Manager and navigate to the “File and Storage Services” page.
  3. Navigate to the Storage Pools page. Refresh the UI by clicking on the Refresh button.
  4. Logon as a user with admin privileges to your server, launch Server Manager, and then navigate to the “Storage Pools” page within the File and Storage Services Role.
  5. Right-click the “Available Disks” pool for the Storage Spaces subsystem and launch the New Storage Pool Wizard.
  6. Launch the New Storage Pool Wizard from the TASKS list.
  7. In the New Storage Pool Wizard, enter desired pool name and optional description. Make sure that you have selected the Primordial pool for the Storage Spaces subsystem.
  8. Select the number of disks needed for pool creation. If you want to designate a physical disk as a hot spare, then select the “Hot Spare” allocation type.
  9. Confirm the selected settings and initiate pool creation by selecting “Create” on the “Confirm selections” page.

Step10: Create a Virtual Disk

  1. Right-click the concrete pool that you just created (the pool where type value is Storage Pool), and then launch the New Virtual Disk Wizard.
  2. In the New Virtual Disk Wizard, make sure that you have selected the appropriate pool. Enter the desired virtual disk name and optional description.
  3. Select the desired storage layout and provisioning scheme as per your storage requirements.
  4. On the “Specify the size of the virtual disk” page, enter the desired size for the new virtual disk or pick the “Maximum size” option.
  • If you pick the “Maximum size” option, the system will try to create the largest size possible for the virtual disk.
  • If you select the check box for “Create the largest virtual disk possible, up to the specified size” while specifying the size then the system will try to create the largest size possible for the virtual disk up to the requested size.
  • It is also important to note that the value showing up as the storage pool free space (in our example 43.8GB) shows the actual free allocation the pool has overall. For cases with a fixed provisioning of a non-simple storage layout such as Mirror or Parity, when defining the size of the virtual disk, you have to take into account the overhead of storage needed to create the extra copies of the virtual disks extents for resiliency. As a basic example, with the 43.8GB free space in the pool, creating a 30GB mirrored virtual disk is not possible since it will take at least 60GB of free space in the pool to create a mirrored virtual disk to hold the two copies of the mirrored data.
  1. Confirm the settings and initiate virtual disk creation by selecting “Create” on the “Confirm selections” page.

Step11: Add Disk to Azure Backup Server

  1. Launch  Azure Backup Server and locate Disk Storage and Add – Select the disk, you want to add
  2. Once Added, this disk will be formatted with REFS file system and the storage will be available for Azure Backup Server.

Now you are ready to use Azure Backup Server. On my next blog, I will explain how to backup VMware VM using Azure Backup Server.

Why Managed vCenter Provider cannot be called Cloud Provider?

Before I answer the question of the title of this article, let’s start with what is public cloud and how a public cloud can be defined.

In cloud computing, the word cloud (also phrased as “the cloud”) is used as a metaphor for “the Internet,” so the phrase cloud computing means “a type of Internet-based computing,” where different services and applications are delivered to an organization through the Internet.

Cloud computing is a method of computing that relies on sharing computing resources rather than having own dedicated local resources to handle workloads such as an application. In this type of computing, unused resources are released back to the pool of resources and reutilised when resources are in demand.

There may be differences in service and application offered by cloud service provider but almost all cloud service provider offer some common services, automation, compliance and utilities to tenant. Almost all major service providers have common characteristics and some has enhanced characterises when comes to cloud computing:

Example: Microsoft Azure Platform or Amazon Web Services

Common Features:

Shared Hardware: By definition public cloud is a multi-tenant environment, resources are shared among clients. Multiple clients are hosted on the same hardware, storage and network devices as the other tenants in the cloud.

Cost effective: Public clouds bring together greater levels of resource and so can benefit from the largest economies of scale. The centralised operation and management of the underlying resources is shared across all of the subsequent cloud services whilst components, such as servers, require less bespoke configuration. Some mass market propositions can even be free to the client, relying on advertising for their revenue.

Ownership and proprietary obligations: You may curious to know who owns what between your cloud provider and you. Your cloud provider owns the layer of physical hardware which you don’t have any control or say what they buy or replace. But you have the ownership of your data, intellectual properties, virtual servers and application. As long as you pay the bills and you do lawful business on hosted environment, your service provider has no rights to switch off or being regular outage on the virtual servers and application without you being notified or compensated.

Enhanced Features:

Self-management: with the high volume, utility model, self-managed systems are required for this business model to make sense. Advantage here for the tech savvy tenants that like to setup and manage the details of their own domain, servers and application by themselves. In this type of cloud based solution provides client with control of their own data and intellectual properties. Self-service is also provide a sense of ownership to a tenant who is willing to manage their own uses of the service and application and keep track of bills and data they own.

Security: Since public cloud is a multi-tenant environment, physical and logical securities are in place to protect a tenant being visible by another tenant. Security is not just placing a Cisco ASA or Juniper firewall in the front of internet and having some virtual switches in vCenter. This is the security that complies with corporate policies and regulations of each territories, the tenant resides.

Hardware Performance: In the public cloud, you cannot select the physical hardware such as compute, cache, network or storage devices. Your virtual server is placed on whatever hardware and network, the cloud provider designates for you. But you have the choice to buy various types of compute, network, load balancer, virtual IP address and storage based on your requirement such as specific IOPS and latency requirement by your application. You can chose to place virtual server with high IOPS capability and very low latency storage. Off course there will extra cost involve by doing so but you will be at least guaranteed performance of the virtual machine. Example: Azure Storage Classification

Network: Even though public cloud is a shared model but you have the choice to procure a dedicated high bandwidth secure network within the shared network guaranteed by the provider. The service provider also guarantees you the security of this network your company procured from the service provider.Example: Azure ExpressRoute

Utility Model: Public Clouds typically deliver a pay-as-you-go model, where you pay by the hour for the compute resources you use. This is an economical way to go if you’re spinning up & tearing down development servers on a regular basis.

No Contracts: Along with the utility model, you’re only paying by the hour – if you want to shut down your server after only 2 hours of use, there is no contract requiring your ongoing use of the server.

Reliability: The sheer number of servers and networks involved in creating a public cloud and the redundancy configurations mean that should one physical component fail, the cloud service would still run unaffected on the remaining components. In some cases, where clouds draw resource from multiple data centres, an entire data centre could go offline and individual cloud services would suffer no ill effect. There is, in other words, no single point of failure which would make a public cloud service vulnerable

Flexibility: There are many IaaS, PaaS and SaaS services available on the market which follow the public cloud model and that are ready to be accessed as a service from any internet enabled device. These services can fulfil most computing requirements and can deliver their benefits to private and enterprise clients alike. Businesses can even integrate their public cloud services with private clouds, where they need to perform sensitive business functions, to create hybrid clouds. Example: Azure Service fabric

Ultimate scalability: cloud resources are available on demand from the public clouds’ vast pools of resource so that the applications that run on them can respond seamlessly to fluctuations in activity. You can acquire a vast pool of resources on to your domain via self-service portal without engaging the service provider. Example: Azure Big Data

Delivery through internet: The availability of public cloud services through an internet connection ensures that the services are available wherever the client is located. This provides invaluable opportunities to enterprise such as remote access to IT infrastructure or online document collaboration from multiple locations. Examples: Microsoft Office 365.

Hybrid Deployments: If a dedicated server is required to run a high speed and high IO database application that on-premises resources can be integrated from a private cloud to public cloud, in effect, hybridising the solution between virtual servers and dedicated servers. The service provider also provides you an option to hybridise your environment you own.

To answer the question, here is my explanation why Managed vCenter Provider cannot be called Cloud Provider?

A single virtual center server is a management point of this type of service provider mostly managed by the small technology team. This type of provider is acting as a trustee of your data instead of a cloud provider. There are possible security and compliance flaws of the systems you may not aware of. There might be potential many single point of failure you may not aware. The bills you received from this type of service provider you never been verified that you truly used those services and application because there is no self-service mechanism with this unscrupulous service provider. There is potential downtime and service outage with this service provider which you have never been compensated. This type of unscrupulous service provider do not follow any service level agreement or respect the agreement they signed. You are sacrificing your productivity by relying on them to provide you a hosted service which you never received with reliably. You cannot simply call them cloud provider. A term should be introduced saying “Managed vCenter” and “Trustee of Data”.

I may be the blogger who is saying this. But here is the global researcher “Gartner Inc.” has to say on who can be called cloud service provider as on May 2015.

Understand “X as a Service” or get stuck in “Pizza box as a Service”

The most traditional use of “X” are Software as a Service (XaaS), Infrastructure as a Service (IaaS), Desktop as a Service (DaaS) and Platform as a Service (PaaS). The other use of “X” are Storage as a Service (SaaS), Communications as a Service (CaaS), Backup as a Service (BaaS), Disaster Recovery as a Service (DRaaS), Network as a Service (NaaS) and Monitoring as a Service (MaaS).

As a CIO or CTO of an organization have you had a business case of your organisation how your organization is benefited from “Anything as a Service”? How does it translate your business in terms of consumption of information technology if it was on premises comparing off the premises or so called cloud. The most service provider compete with each other getting a piece of pie from these cloud computing era. However to cut cost these provider going below the bench mark and taking the cloud into “Craig list” where everything offered cheap scarifying quality making it “Pizza box as a Service”.

Here are some guidelines for you to measure your workload, services and application before signing up with a cloud provider.

  1. What type of services or application you would like to migrate to cloud?
  2. Are you migrating tier 1 application to cloud?
  3. What is your peak demand of IO or IOPS for all virtual infrastructure, VDI, services and application?
  4. What is peak period latency requirement for an application and a service of your organisation?
  5. What is your peak bandwidth requirements?
  6. What is the up time requirements?
  7. What is SLA and SLR of your business with the service provider?
  8. Do you have penalty clause with the service provider?
  9. What is your RPO and RTO to business when choosing DRaaS?
  10. What is corporate compliance and data retention policy when choosing BaaS?
  11. Do you have good/great user experience matrix in your organisation?

Once you have answered these question, gather data from existing infrastructure and analyse your requirement than it’s time for you to;

  1. Prepare a business case for Anything as a Service
  2. Identify option1, option2, option 3 for cloud services
  3. Knowing cloud provider
  • Learn more about cloud provider hosting platform
  • Learn more about cloud provider engineering and support capabilities
  • Learn more about cloud provider outbound bandwidth and redundancy of network infrastructure
  • Learn more about redundancy of storage infrastructure of cloud provider
  • Who are the hardware and software partners of cloud provider
  • How user friendly is the management portal of cloud provider

4. Compare and select potential cloud provider

If you haven’t identified above criteria and you are aware that you signed up with a cloud provider who simply patch together a 1Gbe network, 1U rack server and Dell Compellent storage with few SATA disk than you signed for a “Pizza box as a service”. You know that your 2WD car is heading towards off road and you are about to get stuck in mud.

When comes decision making time, count every factor into account and make a decision that provide an outcome you want instead of cheap pizza box as a service which neither fulfil your requirement nor fulfil SLA of your business. Remember it’s about your business not the business of cloud provider.
