The new business demands and challenges pushed IT organizations and Pros to rush into using virtualization/cloud technologies, with this push comes a huge challenge in selecting the proper backup method and spotting the key factors to consider when designing backups for virtual machine.
To help you addressing this challenge and spotting those points, we will release a white paper that identifies key elements to consider when backing up and recovering virtual machines and explains them in details.
So stuff like Agent or agentless backup, unified or virtual specific backups, Data Deduplication (how, when) with virtual machines, large backup sets, granular vs. one backup/restore set, adding to that great and critical tips for applications (AD, SQL and Exchange), Hypervisors (VMware/Hyper-v) and network layer.
This unique white paper has been written by a group of the best minds in applications, virtualization and backup worlds, the authors of this white paper are:
- Thomas Maurer: Thomas is Hyper-v MVP, well known in his contributions in System Center, Hyper-v and cloud community.
- Mikko Nykyri: VMware vExpert and virtualization product mangaer for backup exec.
- me, Mahmoud Magdy
In this white paper; Published at Symantec here http://ow.ly/kOQBJ , we bring you the top points to consider, key factors and top issues to identify when backing up and restoring virtual machines, we will also go through a Google hangout session discussing those elements in details.
so start tuned, and follow us on Twitter, Linkedin and facebook and wish you all happy backup and successful restore.
Since a while I was thinking about helping others posting their TRUE knowledge and skills, I seen a lot of guys roaming around with no clues how to build true knowledge about IT infrastructure in general.
In this blog series, I will list recommended reading for several technologies and components and how you can build knowledge around that, of course; hand-on and time will give you the required experience, but these recommendations will help you to stop the no-clues auto-pilot mode.
I will start with AD, please note the following:
- You might have different opinions about the readings, again these are my recommendations.
- I read the below list so when I complied this list I wanted to cut it short for you instead of reading useless stuff.
- You will still need to build hands-on experience.
so let us start with the Active Directory reading lists:
This list will be updated on regular basis to reflect the most recent interesting reads, I wish you all successful career in AD.
Through a trusted resource at the product group, we got the information that sp1 of Exchange 2013 will support running from removable media such as flash drives, dvd drives and blue ray disks, this will allow greater flexibility and decouples the sw layer from hw layer allowing exxhamge to be delivered as remote application over terminal service session or running it as
portable app over linux machines
What a great news, can’t for service pack 1….
the use of OWA redirect rule is very famous now, this has been outlined in several blog post, the best and the original was Brian’s post here http://briandesmond.com/blog/redirecting-owa-urls-in-exchange-2010/
however, careful must be taken when configuring the above rules specially when you are going to use RSA SecureID authentication, the above configuration will prevent the clients on the OWA from accessing the WebID virtual directory and the browser will stop at the path OWA/WebID/IISWebAgentIF.dll with a blank page.
to solve this issue, you will need to stop the redirect and use another method (maybe Java redirect script) because you will not be able to use RSA SecureID with the redirect.
other notes to be considered when configuring OWA with RSA SecureID:
- Make sure to follow the steps outlined in the WebAgent_IIS.pdf document.
- make sure to configure the RSA application pool with admin account (this is mentioned in the document but can be easily overlooked).
- make sure to have the securid file created (install the Windows Agent and do test authentication), the documentation instructs you to download the RSA SDK and use the agent_nsload.exe and convert the file to the web agent format, this is not correct, just copy the file form the authdata folder to the web agent installation directory.
you receive “Authentication Method Failed” on the RSA authentication monitor and “authentication failed” error message on the RSA security Center
Consider the following scenario, you installed the RSA Windows agent and added the agent, when you test the login you receive “Authentication Method Failed”.
you are using the correct Passcode or SecureID code, so what is the issue:
The issue happens because you are using server that is multihomed, when you create the agent you specify the IP that will be used by that agent, the agent might use incorrect IP although in real-time reporting, you will see the agent IP presented correctly.
to overcome this issue, RSA has KB a37416 that specifies the solution, you can read it over RSA knowledge base if you don’t have access then:
- Configure IP override, from the advanced settings in the RSA security center, make sure to specific IP override that will use the same IP configured in the Agent settings on the security console.
simple, but yet tricky issue.
Configuring your Web Interface to work with RSA SecureID can be troublesome, I spent 2 days trying to figure how to make it work, here are the configuration steps:
Follow the steps mentioned in this CTX article: http://support.citrix.com/article/CTX126843
BUT, as usual there is a trick, completing the above configuration will not work, you will get the following error:
There was a problem with the RSA SecurID ACE/Agent. Check that the ACE/Agent is installed correctly and that the path to the file aceclnt.dll has been added to the PATH environment variable.
To solve this problem, first, follow the following steps:
- make sure to install the RSA Web Agent, the Web Agent must be installed as it will add some keys in the applicationhost.config that are needed by the IIS.
- Configure the Web interface not to send the domain name, from Explicit authentication, properties, Explicit/Two-Factor Authentication and uncheck (Send Domain and username to ACE/Server)
some additional troubleshooting steps are here (Like the PATH and secret key reset)
In a recent post, the private cloud architecture team posted an interesting blog http://blogs.technet.com/b/privatecloud/archive/2013/02/26/destination-private-cloud-are-we-there-yet.aspx which talks about the characteristics of the private cloud.
being one of those who are working on the cloud, in the cloud and by the cloud, I think that we can answer, no we are not there yet.
the blog talks about the main characteristics that needs to be available for you to say; I have a private cloud, but I am speaking about the hall picture.
the hall picture comes with a lot of things, HW integration, network integration, Security integration and a lot more.
yes, most of the “Private Cloud” providers, provide their own solution to have an end-to-end solution, but it is still locked, for example Microsoft does HW fast track, but with limited set of vendors and HW providers.
adding security, Backup/DR and networking to the show, you will have a more complex scene, in my opinion; we don’t have the cloud-ready security/network solution yet, they will come, but we are not there yet.
my 2 cents for you if you are working on your own “cloud” project, take a deep look, and don’t think it is easy to use, consume or build a cloud, because we are not there yet.
Last week I published around 3 episodes to help you move your Exchange 2010 organization to Office 365, all session are in Arabic helping the Arabic community to move to the latest edges for technologies.
the sessions can be found here:
Session 4 and 5 are being recorded, so hand on and let me know your feedback about the Episodes
if you got this error in your Citrix receiver client and you can’t connect to the server, please use the following methods to address this issue:
Apply the following hotfixes:
- http://support.microsoft.com/kb/2254637 (although the hotfix is not RDP related)
if the issue is not fixed, make sure to delete or rename the usrclass.dat in the c:\users\default\appdata\local\microsoft\windows , it looks like a corrupted file can cause this issue for new and exiting users.

Follow up: based on my search and testing, I found that removing users’ permissions from tstheme.exe massively increases the speed of the login
