QuadstorVTL is a nice piece of software for virtualized Tape Backups.
I’m using it for around 2 years and mainly for testing purposes on Debian Wheezy with DPM 2012 long term tape backup on Hyper-V.
From a Hyper-V perspective I would stick on Suse Linux, Ubuntu or maybe CentOS/RedHat as I described two months ago rather than Debian.
I started using QuadstorVTL on Debian because I needed an OOB solution for QuadstorVTL with minimal installation expense.
After a while and 2 Hyper-V generations later, Debian became more and more old fashioned and outdated compared with Ubuntu or Suse.
The missing KVP daemon and the lack of dynamic RAM support within Hyper-V environments isn’t suitable anymore.
Suse Linux would be the preferred distro on Hyper-V but my skills are a bit behind Ubuntu and so I decided to switch to the latest Ubuntu LTS 14.04 and try to get this running.
It’s not a “little expense” solution anymore but I like Ubuntu and the benefits are worth the effort.
Unfortunately the list of supported systems doesn’t include Ubuntu and after an installation of the VTL deb package, the Apache server won’t give you the well-known webinterface.
With help of the support team I got it running. Continue reading →
I struggled with a Live Backup issue on Ubuntu 2014 LTS a while ago as ralish from Stockholm DevOps describes here.
The problem was a broken installer meta package and ends up in a missing kvp deamon if you tried to install it on Ubuntu.
This daemon is used to interact between Host and VM to get a consistent backup state during snapshot creation on the Hyper-V Host.
So at the end, Backups without kvp can be risky due to a service interruption of the VM workload(s).
A screenshot from the DPM 2012 R2 Backup console shows the offline state.
In the meantime, the bug got fixed, Live Backups without service interruption can be taken, the sun is shining again and so it’s time to wrap some things up and give you a short overview about Hyper-V and common Linux Distributions.
