New version of virtual machine which can be used to testing and training.

MHVTL is a open source VTL project developed by Symantec employee - Mark Harvey. (

I added ISCSI functionality by integrating MHVTL with STGT (


Ubuntu Server 11.04 x64 (without kernel patching and recompilation)
VMware Virtual Machine (Fusion, Workstation)

IP: (/etc/sysconfig/network)
login: user1
pass: user1
root - "sudo su -"

300 GB btrfs filesystem on lvm (lvm and btrfs can be easily resized)

mhvtl 0.18-16
stgt 1.0.17 (ISCSI targets)

1x L700
4x LTO4 (compression factor=1)
60x LTO4 tape (5GB)


ISCSI STGT targets are created automatically after mhvtl start.

start/stop commands:
/etc/init.d/start-mhvtl-iscsi start
/etc/init.d/start-mhvtl-iscsi stop

BTRFS filesystem has snapshot functionality so we can create snapshots of mhvtl setting and tape data, for example:
btrfs subvolume snapshot  /opt/mhvtl /opt/snapshot/mhvtl_12_06_2001
btrfs subvolume snapshot  /opt/etc /opt/snapshot/etc_12_06_2001
(/etc/mhvtl linked to /opt/etc/mhvtl)


Backup and restore tested with NetBackup 7.0.1 installed on Windows 2008 x64 R2

Virtual machine can be imported into VMware ESX infrastructure using VMware Converter.

Hello Marek,

could you briefly describe how to use this vmware appliance?

Do I need another system wth win2k8?

Hi Marek,

    Could you please upload a new (live) link to download the vm? I'm a new user to Netbackup and I'm attending Symantec Netbackup seminars, so this will be useful for me.


Both links are not working anymore :(

Hi Marek, 

Could you please re-upload, both links are dead



New link :




Much Thanks Marek... Your magical touch to mhVTL rocks.


I converted the original VM 7 format to VM 8 so that it could be hosted in new versions on VMWare Workstation (8/9) and ESXi 5.1.
