Bare Metal Restore

Create restore media

1. In the Management Console of the Backup & Disaster Recovery appliance, go to the Settings tab.

2. In the Tools group on the left, click Downloads.

3. In the Bare Metal Restore group, download the restore disk image (DR Restore Disk).

   

4. Create a bootable media (for example, a USB flash drive) from the downloaded image.

Restore from the disaster recovery image

1. Insert the previously created recovery media into the target computer, or mount the Bootable Media ISO on the virtual machine to which you want to restore.

2. Start the computer and boot from the restore media.

3. Select Infrascale Baremetal Recovery. 

   

4. The Infrascale logo will appear. Wait for the boot process to be completed.

   

5. Once the Bare Metal Restore application is started, select the target disks to which the restore should be performed and click Next.

   

6. Select Infrascale Appliance as the Source Location to restore from the local Primary or Infrascale Cloud to restore from the cloud, and then click Next.

   

7. If Infrascale Appliance was selected, the list of available appliances opens.

   If the target computer has a hardware or a hardware-assisted software RAID, before continuing, please check if the DR restore disk supports the RAID controller, and thus can perform restore as per the RAID configuration.

   1. In the list of available appliances, select the appliance you want to restore from and click Next.

      

      If the system does not show any appliances on the list, click Rescan Network to automatically detect appliances available on the network.

      If the system is still unable to detect any appliances automatically, enter the Host address of the appliance and click Add.

      The Login window opens.

   2. In the Login window, enter the password used to log in to the appliance Management Console, and then click OK.

       

   3. The list of protected clients associated with the appliance opens. In the list of clients, click the client you want to restore, and then click Next

      
      
      

8. If Infrascale Cloud was selected as the Source Location on step 6, step-by-step instructions for connection configuration are shown:

   

   Follow the instructions as shown below and click Next

   1. Log in to the Infrascale Dashboard by clicking the link and providing the credentials

      
      
      

   2. Navigate to the Disaster Recovery > Hybrid Cloud Status
      
      

      

   3. Under Primaries section, select the client machine you wish to restore, download the Cloud Configuration file, select and copy the UUID.
      
      

      

   4. Return to the Bare Metal restore tool, select the Cloud Configuration file downloaded on the previous step, paste the UUID, and click Next
      
      

      

9. Select the required snapshot based on the desired restore date and click Next
   
   

   

10. Configure the Disk Mapping as required and click Next
    
    

    

    The VM or physical server used for recovery must have equal or greater disk size compared to the original source system

11. The restore process will begin. You will be able to see the disk restore progress.
    
    

    

12. Once the restore completes, click Reboot and confirm Yes. After reboot, the machine should come up successfully in the restored state
    
    

    

Remove the restore media when restarting the computer.

Check RAID controller support

If the computer you plan to restore to has a hardware or a hardware-assisted software RAID, you may check if the DR restore disk supports the RAID controller, and thus can perform restore as per the RAID configuration.

For this, after booting the target computer from the restore media:

1. Next to the Help icon, click More (), and then select Open Shell.

   

2. View information about the SCSI devices attached to the system.

   For this, run the lsblk command followed by the -So options and the +SIZE parameter.

   lsblk -So +SIZE 

   The system lists all SCSI devices currently attached.

   

   Check if the system detected the RAID controller.

   • If the RAID controller is on the list, this means the DR restore disk supports it.

   • If the RAID controller is not on the list, this means the DR restore disk does not support it by default.

     You have to find and install drivers for the RAID controller manually before proceeding with the restore. If necessary, contact Infrascale Support for assistance.

3. Next to the Help icon, click More (), and then select Close Shell, and continue restoring.

   

Example check:

Suppose we have a computer with LSI MegaRAID SAS 9266-4i controller.

We list all SCSI devices attached to the system.

lsblk -So +SIZE 

In the output, we see that the system detected a block device named sda with the size of 36.4 TB and managed by our RAID controller LSI MR9266-4i.

NAME HCTL TYPE VENDOR MODEL REV TRAN SIZE sda 0:2:0:0 disk LSI MR9266-4i 3.44 36.4T sdb 2:0:0:0 disk ATA INTEL SSDSC2BB24 0130 sata 223.6G sdc 7:0:0:0 disk ATA SATA SSD 02.1 sata 14.9G sdd 1:0:0:0 disk SanDisk Ultra 1.00 usb 57.3G 

Now, we can continue restoring.
