NetBackup™ Deduplication Guide

To convert the Windows 2016 VM image to VHD

1. Enure that you enable Remote Desktop Connection on your source VM before backup.
2. Perform a new full backup of the source VM,
3. Prepare image sharing server and configure image sharing feature with azure account.
4. Import the backup image and perform the conversion.
5. Verify the converted vhd files.

   In Azure web Portal:

   • Create a disk with the converted .vhd file

   • Create a VM with the previous disk.

     Navigate to Disks > Created disk > Create VM. With default Networking & Disks & Management settings, enable boot diagnostics.

   • Login the converted VM through RDP.

To convert the RHEL7.6 VM image to VHD

1. Install latest LIS 4.3.5.

   tar -xzf lis-rpms-4.3.5.x86_64.tar.gz

   cd LISISO

   ./install

   reboot

2. Rebuild initramfs image file.

   cd /boot

   cp initramfs-`uname -r`.img initramfs-`uname -r`.img.bak

   Run the following command to open dracut.conf file:

   vi /etc/dracut.conf

   Uncomment the line #add_drivers+=""

   Add the following drivers to the line, separating each module with the space.

   hv_netvsc hv_storvsc hv_vmbus

   Example,

   # additional kernel modules to the default.
   add_drivers+="hv_netvsc hv_storvsc hv_vmbus"

   Create new initial ramdisk images with new modules.

   dracut -f -v -N

   Run any of the following commands to check if the new modules exist in new initial ramdisk images.

   lsinitrd | grep -i hv

   lsinitrd -f /boot/initramfs-`uname -r`.img | grep -i hv

   modinfo hv_netvsc hv_storvsc hv_vmbus

3. Rename the network interface to eth0 and enabled on boot. After this change, reboot VM to check if eth0 works.

   In the network interface configuration file, configure: ONBOOT=yes.

   The example to change the network interface to eth0:

   mv /etc/sysconfig/network-scripts/ifcfg-ens192 /etc/sysconfig/network-scripts/ifcfg-eth0

   sed -i 's/ens192/eth0/g' /etc/sysconfig/network-scripts/ifcfg-eth0

   In the file /etc/default/grub, change the line GRUB_CMDLINE_LINUX="xxxxxxx" to GRUB_CMDLINE_LINUX="xxxxxxx net.ifnames=0 biosdevname=0"

   grub2-mkconfig -o /boot/grub2/grub.cfg

4. Perform a new full backup of the source VM,
5. Prepare image sharing server and configure image sharing feature with azure account.
6. Import the backup image and perform the conversion.
7. Verify the converted vhd files.

   In Azure web Portal:

   • Create a disk with the converted .vhd file

   • Create a VM with the previous disk.

     Navigate to Disks > Created disk > Create VM. With default Networking & Disks & Management settings, enable boot diagnostics.

   • Login the converted VM through RDP.

To convert the SUSE 12 SP4 VM image to VHD

1. Make sure the required modules are installed.

   • lsinitrd -f /boot/initramfs-`uname -r`.img | grep -i hv

     or

     modinfo hv_vmbus hv_storvsc hv_netvsc

     reboot

   • Rebuild initrd.

     cd /boot/

     cp initrd-$(uname -r) initrd-$(uname -r).backup

     mkinitrd -v -m "hv_vmbus hv_netvsc hv_storvsc" -f /boot/initrd-$(uname -r) $(uname -r)

2. Check the network interface name eth0 and enabled on boot.

   /etc/sysconfig/network/ifcfg-eth0 contains the record:

   STARTMODE='auto'

3. Perform a new full backup of the source VM,
4. Prepare image sharing server and configure image sharing feature with azure account.
5. Import the backup image and perform the conversion.
6. Verify the converted vhd files.

   In Azure web Portal:

   • Create a disk with the converted .vhd file

   • Create a VM with the previous disk.

     Navigate to Disks > Created disk > Create VM. With default Networking & Disks & Management settings, enable boot diagnostics.

   • Login the converted VM through RDP.
