Lync Server 2013 - Disaster Recovery Plan

Hi All,
I am looking for a document which has the information about the different scenarios regarding High Availability and Disaster Recovery and things to perform during that situation
Eg.
If a front end Server is failed. then the load will be moved to another front end server in the pool
similarly back end Server fails, then the load gets moves back to SQL mirroring server by SQL Witness server

Same Server 2013 Disaster Recovery using Database Portability

Hi,
I need to rebuild a 2012 Server with AD (Domain controller) + Exchange 2013 starting totally from scratch.
I do have a copy of the clearly unmounted Mailbox Database.
For whatever reasons, the new server MUST use the old Computer Name and the old AD domain configured as a new forest on the new server. So, the old DC was DC.mydomain.com and it has to be the same on the new machine.
I did the AD configuration respecting these constrains.
When it comes to Exchange 2013, I did a clean install of the 2013 CU3 (same as it was on the old server) and used the same organization name (as required by Database Portability). Then, I followed the procedure reported at: http://technet.microsoft.com/en-us/library/dd876926%28v=exchg.150%29.aspx
and sadly, when I run the
Get-Mailbox -Database <SourceDatabase>
I get no results, even if the DB contains several mailboxes.
I double checked every step of my procedure also according to different forum/blog posts I found googling but no luck.
Please, give me an advice.
Any help is appreciated.

I believe that you might be able to mount an EDB file under the circumstances you describe.
Get-Mailbox does an Active Directory lookup of users, and returns the mailboxes it finds. Simply restoring the database does not populate all the data in AD with the mail-enabled attributes. You might be able to do that by using Connect-Mailbox
to connect the user account with the disabled mailbox in the database.
So, if you can get the database (with no log files) mounted using Mount-Database -AcceptDataLoss, then you might be able to use Connect-Mailbox to connect the newly-created user accounts with the disabled mailboxes in the database you mounted.
I believe this should work, but I've never had to do it myself, so I can't promise anything.

How do I enforce "Show My Picture" instead of "Hide My Picture" in Lync Server 2013?

I was scouring TechNet and the web for a script that could perform the same task as one that I previously used for Lync 2010.
In Lync 2010, we had already used Lync policy to enforce that only the Active Directory photo could be used. One thing that we couldn't set via policy however was the ability to complete remove the "Hide My Picture" option in Lync 2010 client.
This left users with the ability to freely switch between showing the Corporate photo or no photo. I did eventually find and make use of script that constantly checked for this setting switch, then switched all users back to the desired "Show My Picture"
setting. I don't recall who wrote it, but it's easy to find on technet. As we started to move more and more users to our Lync 2013 enterprise pool, I noted that even though the script was running, the setting seemed to be changeable. A closer look revealed
that the script didn't function correctly against SQL for our 2013 pool.
I took the concept and applied it to Lync Server 2013 after studying the differences in Userdata. In Lync 2013, because UserData is in .zip, you need to convert it to 2010 format XML to use logic intended for Lync 2010. My script will extract 2013 data,
convert it to 2010, query for users who are set to "Hide My Picture" and then export any guilty users to an edited2010 XML. The script then converts this to 2013 Format .zip, and uploads the data for these users only. I chose to use Update-CSUserData
insted of Import-CSUserData as this avoids having to restart my Front End. I then use a scheduled task on my Front End server which runs this script every hour.
Please note: You can use this script, but I guarantee nothing about it's functionality, and I am not responsible for how you positively/negatively use it. You should always test things in a Lab Environment. Furthermore, this script was run on a relatively
smaller Enterprise system in which we are by default set to "Show My Picture" and already assigned as part of our user policy the ForceADPhoto attribute. This means that running the script is less intensive on my FE than say on a FE with 10,000 users
where none of the users were set to "Show My Picture". Please keep this in mind when planning to execute against your FE. You may want to edit my script and insert the -UserFilter or -WhatIf in the Export-CsUserData UpDate-CsUserData.
Anyways, I hope this solves the similar issue for many of you Lync 2013 administrators. Please feel free to share my work with others if it does, and also give this post some good feedback and/or mark my post as the answer to your problem.

Disaster Recovery Plan

We're running xMII 11.5 SP3 in a three-tiered centralized server environment (Development, Staging and Production). We plan on having a project up and running in production by October 1. Before we do so, however, we need to develop a disaster recovery plan in the event of a failure of our production server. Our staging server is in a different city and we plan on using it as our temporary production server.
Does anyone have any recommendations on putting together a disaster recovery plan for this scenario?
Thanks!

Dave,
Good to see you active on the forums, hope all is well...
As for disaster recovery the procedures will follow along similar to your roll out plan, where content is moved from Dev -> Staging -> Prod. The main difference will be that you will have to reconfigure the xMII system. In 11.5 this is all file based XML files in the following directories:
<Drive>:\Lighthammer\Illuminator\conf
<Drive>:\Lighthammer\Illuminator\sysconf
<Drive>:\Lighthammer\Illuminator\properties
<Drive>:\Lighthammer\Security\*
<Drive>:\Lighthammer\Xacute\Configuration
These are the main ones, there may be others depending on your development specifics.
Hope this helps.

Hi,
The disaster recovery strategy should include a backup and restore plan that determines which data should be backed up and the procedures that will be used to recover it.

Lync Server 2013 Installation Error

Hello,
I am using my AD in Windows Azure VMs. I created new VM of A3 (4 cores, 7 GB Memory) Windows Server 2012 R2, Port 1433 MSSQL added, made it a member of Domain and planned to install first Lync Server 2013 on it.
In "Setup or Remove Lync Server Components" of "Install or Update Lync Server System", got an Red Coloured text "An error
occurred while applying SQL script for the feature BackendStore."
I have not enabled monitoring and archiving server in topology builder. I added "Network Service" and assign "Full Control" in Security Permissions of "C:\CsData" and "C:\LyncShare".
I executed the SQL Setup Wizard and upgraded any instance to 2012.
Please guide.
Thanks, Divyaprakash Koli

Lync Server 2013 in a Remote Desktop Environment

Hello Community,
We have a client who is sold on Lync. He wants to install Lync server in a Terminal Server but his environment is RDHS 2008v2 and his end users have thin clients. According to MS official position It is not supported. Has anyone successfully implemented
this ? If yes what are the pitfalls that lay ahead with regards to audio/video redirection, desktop sharing etc. He has traditional phones but really he wants to get rid of them and go Lync full blown.

The Virtualizing Lync Server 2013
(WindowsITPro) article presents a nice overview to this topic.
In additon, do take a look at the following resources which may be helpful:
Planning a Lync Server 2013 Deployment on Virtual Servers

Note that unlike Lync Server 2010, the Lync 2013 VDI browser plug-in is designed to support VDI environments (with paired audio/video) running on supported platforms (from Windows Server 2008 R2 to 2012/R2).
Hope this helps.

How to run a Lync Server 2013 in amazon ec2 Instance ?

Hi Friends,
I would like to install a Lync server 2013 in amazon ec2 instance. Let me know can i install Active Directory server, Lync Server 2013 and Media server in a single amazon instance ?. If it possible how can i do it ?. And is any other features need to install
to get the fully functional Lync server. Please help me am newbie in Lync environment

You can get Lync working in EC2 and I have lab'd his many times. Having said that the process isn't that straight forward (especially if you plan to do voice) a lot of planning and testing, specifically of the network would need to be undertaken.
You can add multiple interfaces to an EC2 instance (see here http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-eni.html)
If you're hard set on using EC2 you can get it to work, but I personally would look at Office 365 E4 or a small on-premise deployment depending on your requirements.

How can I connect the phone network to LYNC Server 2013?

Greetings,
We have a working implementation of Lync Server 2013 (pc to pc), our objective is to connect lync to our phone central, receive and send calls from lync clients (pc, phone, etc), basically enterprise voice services.
I would like to know the following:
Hardware that I need for this beside the server.
Extra configurations that must be done.
If you could recommend me the hardware needed it would be helpful.

You'll need a gateway typically. You can find a list of qualified IP gateways here: http://technet.microsoft.com/en-us/office/dn788945.aspx
I typically lean towards the AudioCodes Mediant line, though many here love Sonus as well. You'll need to pick a method to connect to your PBX before you begin, such as via a T1/E1 trunk, FXO ports, or a SIP trunk depending on what your PBX will
support.
You'll need to configure the PBX to route calls through the T1 towards Lync and vice versa. You'll also need to configure the gateway itself, so I'd go with a consultancy with experience here or purchase remote implementation support from the hardware
manufacturer.
On the Lync side, you'll need to configure dial plans, voice policies, usages, and routes:

HLB for Lync Server 2013 Standard Edition

Hi Guys,
I am planning to add an additional new Lync Central site with paired Lync Server 2013 standard edition in Primary and DR data centers. with 1 or 2 OWAS Servers in each DCs. No Edge
server in this new Lync central site as we already have an Edge pool in another central site for federation. Only IM & P and Conferencing, no External Access, Mobility and EV.
My question is, for LS2013 Standard edition paired pools in the new Lync Central site. should I use HLB or DNS LB should be ok? as technically we do not have any HA here only DR.
Any advantage using HLB over DNS LB in LS2013 Standard edition?
Thanks for your help.
Cheer....

You typically wouldn't need HLB with standard edition at all. What were you planning to accomplish?

IOPS & Lync Server 2013 - Guidance

Is there any formula MS released for IOPS calculation for Lync Server 2013.
Do we need to take IOPS into consideration for Lync Server 2013 while planning, how to calculate the Lync Server 2013 IOPS requirements?

The official disk guidelines are here:
https://technet.microsoft.com/en-us/library/gg615015(v=ocs.15).aspx but they don't mention IOPS specifically. The front ends in 2013 can get beaten a bit due to all the presence subscriptions and related queries.
They also touch on it a bit when it comes to virtualization:

SQL Server Sizing for Lync Server 2013

Hi,
We are planning to install Lync Server 2013 with 800 users, but I can find any information about the SQL Server instance sizing.
Can anyone give me an estimation or prior experience with similar installations? I need to know Disk size, memory an CPU number.
Thanks in advance.

There are a few variables to consider. Are you turning on monitoring, archiving, and is enterprise voice enabled? Is persistent chat enabled? Is it virtualized? Is this Lync enterprise edition or standard with a portion of the
databases hosted on full SQL? Are you required to retain any information or logs for a specific amount of time? Are you keeping SQL backups local with maintenance plans and for how long?
I would suggest not going below 16GB for a SQL Server, but you may not need much more. If it's virtual I'd throw 4 cores at it at least and disk space will vary based upon what you're doing and how long you want to keep things. Thick provision
those drives and make sure the logs and databases are on separate partitions.
