A vCenter user account has, at least the following privileges, which are required for successfully protecting a VM. The following table captures the privileges that you need to assign to the user account that you create:.
On the Summary screen, select the server you want to add, and click Add. If your organization does not want to use secure communication protocol HTTPS , you can create a registry key to disable it. To create this registry key:. Save the file with the name, DisableSecureAuthentication. However, before you begin protection, you need to allocate disk storage that DPM can use for short-term storage.
Once you select a folder for protection, all folders and VMs within this folder are automatically detected and protected. This is called folder-level protection. DPM supports scale-out protection of VMware server clusters. The new scale-out feature removes the limit of a one-to-one relationship between a VMware cluster and a DPM server. To deploy scale-out protection, there must be a minimum of two DPM servers.
When protection groups on D1 or D2 are created, any virtual machine can be added. You specify the protection method while creating the new Protection Group. For all operational recovery scenarios like accidental deletion or corruption scenarios, back up to disk. For long-term retention or offsite backup requirements, back up to tape or cloud. For long term retention on VMware backup data on-premises, you can now enable VMware backups to tape.
The backup frequency can be selected based on the retention range which will vary from years on tape drives. The data on tape drives could be both compressed and encrypted. In the Select Group Members screen, expand the Available members folders and select the folders to protect and click Next.
Once you select a folder, the member is added to the Selected members list. Items already protected by a DPM server cannot be selected again. View the DPM server that protects an item by hovering over the item in the Available members list. On the Select Data Protection Method screen, type a Protection group name , and then select the protection method. For protection method, you can choose: short-term protection to a hard drive, long term backup to tape, or online protection to the cloud.
Once you've selected your protection method, click Next. If you have a standalone tape or tape library connected to the DPM server, you'll be able to select I want long-term protection using tape. If you want to change the schedule when application recovery points are taken, click Modify.
On the Express Full Backup tab, choose a new schedule for the time s and days of the week when Express Full Backups are taken. When you have the short-term goals you like, click Next.
If you want to store data on tape for long-term storage in Specify long-term goals , indicate how long you want to keep tape data years. In Frequency of backup , specify how often backups to tape should run. The frequency is based on the retention range you've specified:. On a stand-alone tape drive, for a single protection group, DPM uses the same tape for daily backups until there is insufficient space on the tape. You can also collocate data from different protection groups on tape.
The Status screen appears and gives you an update on the creation of your protection group, and the state of your initial backup. For an overview on using DPM to recover data, see Recover protected data.
When recovering data, you may, or may not want to restore data or a VM to the same location. You can restore individual files from a protected VM recovery point. This feature is only available for Windows Server VMs. Restoring individual files is similar to restoring the entire VM, except you browse into the VMDK and find the file s you want, before starting the recovery process. To recover an individual file or select files from a Windows Server VM:.
Using the Browse pane, browse or filter to find the VM you want to recover. Once you select a VM or folder, the Recovery points for pane displays the available recovery points. In the Recovery Points for: pane, use the calendar to select the date that contains the desired recovery point s. Depending on how the backup policy has been configured, dates can have more than one recovery point.
Once you've selected the day when the recovery point was taken, make sure you've chosen the correct Recovery time. If the selected date has multiple recovery points, choose your recovery point by selecting it in the Recovery time drop-down menu. Once you chose the recovery point, the list of recoverable items appears in the Path: pane.
The application of these system updates is controlled through the Security Center in the Azure portal. After you apply some updates, VM reboots might be required. For more information, see Apply system updates in Azure Security Center. Like on-premises servers, Azure does not push updates from Windows Update to Windows VMs, because these machines are intended to be managed by their users.
You are, however, encouraged to leave the automatic Windows Update setting enabled. Automatic installation of updates from Windows Update can also cause reboots to occur after the updates are applied. There are other cases in which Azure might actively suspend the use of a VM. You'll receive email notifications before this action is taken, so you'll have a chance to resolve the underlying issues. Examples of issues that affect VM availability include security violations and the expiration of payment methods.
The VM is hosted on a physical server that is running inside an Azure datacenter. The physical server runs an agent called the Host Agent in addition to a few other Azure components. When these Azure software components on the physical server become unresponsive, the monitoring system triggers a reboot of the host server to attempt recovery.
The VM is usually available again within five minutes and continues to live on the same host as previously. Server faults are usually caused by hardware failure, such as the failure of a hard disk or solid-state drive. Azure continuously monitors these occurrences, identifies the underlying bugs, and rolls out updates after the mitigation has been implemented and tested.
Because some host server faults can be specific to that server, a repeated VM reboot situation might be improved by manually redeploying the VM to another host server. This operation can be triggered by using the redeploy option on the details page of the VM, or by stopping and restarting the VM in the Azure portal.
If the host server cannot reboot for any reason, the Azure platform initiates an auto-recovery action to take the faulty host server out of rotation for further investigation. All VMs on that host are automatically relocated to a different, healthy host server. This process is usually complete within 15 minutes.
To learn more about the auto-recovery process, see Auto-recovery of VMs. On rare occasions, the Azure operations team might need to perform maintenance activities to ensure the overall health of the Azure platform. This behavior might affect VM availability, and it usually results in the same auto-recovery action as described earlier. VMs might restart because of issues within the VM itself. The workload or role that's running on the VM might trigger a bug check within the guest operating system.
For help determining the reason for the crash, view the system and application logs for Windows VMs, and the serial logs for Linux VMs. VMs in Azure rely on virtual disks for operating system and data storage that is hosted on the Azure Storage infrastructure.
