Data Protection & High Availibility – upcoming new features – Part 2

Microsoft announced different cool features at the TechEd 2014 in Barcelona and I needed some time to get into all the cool new stuff.
Especially the tracks of Data Protection and High Availability got me.
There are major and minor changes with Hyper-V, Data Protection Manager and Azure which makes life easier and HA/DP better.

Here’s a series of conclusions of the changes and new features from all over different sessions.

2. A new Reporting Framework

Another missed thing, is an accurate and reliable reporting feature.
At the moment DPM doesn’t have good reports especially for environments with more than one DPM server.
The reporting engine is only usable for one single server for example.
I’m sure you really desperate to get something better.

Data Protection & High Availibility – upcoming new features – Part 1

Microsoft announced a number of cool features at the TechEd 2014 in Barcelona and I needed sometime to get into all the hot new stuff.
I found the Data Protection and High Availability tracks especially captivating.
There are major and minor changes to Hyper-V, Data Protection Manager and Azure which make admin life easier and HA/DP better.

Here’s a series of summaries on the changes and new features from all over the different sessions:

1. Virtualized Backups

They’re finally in. Rumors came up this summer and most people guessed the UR3 for DPM 2012
R2 would add a dedup feature to DPM.
As we now know, it was not available in the original UR3 but is now fully supported after the November 2014 update.

The reason why dedup was a painfully missed feature is the huge amount of data required for DPM compared with other vendors’ solutions.
Almost of the people to whom I talked about DPM agreed: “We need dedup!”

A channel9 session with Dik van Brummen points this out nicely.

Linux on Hyper-V – a summary 10.2014

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.

The full error message is:

Starting up a scheduled Replication Job in DPM 2012/R2 … immediately

Sometimes i’m creating scheduled replication tasks because i’m still working on servers and systems or i have performance considerations.
Surprisingly often I’m finished earlier than expected and would like to start the postponed tasks as soon as possible.


But i couldn’t find DPM specific tasks within the task scheduler and starting the job with the usual way via GUI wasn’t helpful. Continue reading
