Instant Boot VM

Instant Boot VM option allows you to instantly access the backup data as a ready state VM within a few minutes. With this option, you can achieve minimal downtime and ensure business continuity by making VMs instantly available.

You can choose to boot your backed-up VMware machine in any of the following hypervisors:

  • VMware (Available if the BDR Backup Server is installed either on Windows or Linux OS)

  • Hyper-V(Available only if the BDR Backup Server is installed on Windows Server OS)

  • KVM (Available only if the BDR Backup Server is installed on Linux OS (Ubuntu)

Step 1: Choose theVM/Host and the Restore Type

  • Select the VM/Host

  • Select the Instant Boot Recovery option and click Next.

Step 2: Choose a Restore Point 

  • Select a restore point to restore the backup data. Vembu BDR Backup Server retains the restore points as per the retention policy you have selected for the backup job. 

  • Full backup and Incremental backup restore points are viewed in the dropdown box structure.

  • Each incremental restore point is a virtual full backup that makes full data recovery possible in each step. This makes the restoration process easier without having to recover a full backup and all the previous increments. 

  • If the restore point is denoted with symbols (d), (w), (m), (+P) at the end, it indicates the following: 

    • Daily Merge (d) 

    • Weekly Merge (w) 

    • Monthly Merge (m) 

    • Persistent boot changes (+P) 

  • Daily, Weekly, and Monthly merges take place based on the retention policies you have configured. 

  • If you select Restore version time-stamp with (+P), then you have enabled the option to ’Include persistent boot changes during restore’ option that includes the changes you performed in the VM/Host during the instant boot restore process.

Step 3: Choose the Target Hypervisor

  • Choose a Target Hypervisor to instantly boot the backup data as a VM.

  • Select any one of the following hypervisor environments from the drop-down:

    • VMware

    • Hyper-V

    • KVM (Applicable for BDR Backup Servers running on Linux)

  • Depending on the target hypervisor, the restore options vary.

Restore to VMware Hypervisor

  • Select the Target ESXi/vCenter in which the booting must take place.

  • If the Target ESXi/vCenter is not displayed in the drop-down list, then click  Add ESXi/vCenter Server option to add a new ESXi/vCenter Server.

  • In the Target Datastore field, the available datastore of the added ESXi/vCenter host will be listed. Using the drop-down list, select the target datastore to which the VM should be added.

  • Choose where you want to store the changes that you will make in the instantly booted VM using the Persistent Data Storage option. You can either store the data in the Native Hypervisor Storage to which the VM is restored or can be stored to the BDR Local Storage of the BDR Backup Server itself.

  • Provide a Target VM Name. This is the name with which your VM will be created in the datastore you have configured. Enter the unique VM name, that you can identify easily in the selected target host.

  • Enable the Power on VM automatically option to power ON the restored VM and click Next to proceed with the restore process. 


Information

Note: 

  1. Only [a-z][A-Z][0-9][ - _ ]characters are allowed in the VM name to be created.

  2. 6 GB RAM will be assigned by default for VMs booted via VMware ESXi in Instant Boot VM.

Restore to Hyper-V Hypervisor

  • You can choose the software as Hyper-V (If your BDR Backup Server runs on Windows Server OS).

  • On selecting Hyper-V as your booting software, the Startup RAM size by default is 2 GB  which can be modified based on your requirement.

  • Provide a Target VM Name for the machine that is to be restored.

  • Once done click Next to proceed with the restore process.


Information

Note: If you assign a higher physical memory (RAM) than the free memory currently available on your server the Instant Boot VM recovery may fail.  


Restore to KVM Hypervisor

  • You can choose the software as KVM (If your BDR Backup Server runs on Linux OS - Ubuntu).

  • On selecting KVM as your booting software, the Startup RAM size by default is 2 GB which can be modified based on your requirement.

  • Provide a Target VM Name for the machine that is to be restored.

  • Once done click Next to proceed with the restore process.

Information

Note: 

  1. If the KVM has an EFI boot, then the boot process will not occur in Instant Boot VM.

  2. If the backed-up Disk Size is more than 2TB, then the boot process is not possible. (Only for Windows Backup)


    Step 4    : Review & Restore

    • Review all the Instant Boot VM recovery configurations and click Restore to instantly boot the backup data as a VM on the selected hypervisor.


    Information

    Note: 

    1. Once you mount the data as a VM, don't forget to unmount the data; You can unmount the data by clicking on the BDR Backup Server Settings tab and selecting the Vembu Virtual Drive option.

    2. On the Vembu Virtual Drive and NFS Share Settings page, all the image-based backup jobs will be listed; you can click on the Unmount button alongside the specific backup job name.
