How Exchange server uses transaction logs

If you have ever wondered why Exchange uses Transaction Logs read on.
The Transaction Logs are an important part of Exchange Server, and are used to store data before it is written to the Database. The Transaction Logs allows uses to send / receive emails, without needing to touch the database thanks to the write-ahead method of logging.
When a message is sent, the transaction is first recorded in the transaction logs. Until the transaction is committed to the Exchange database (EDB), the only existence of this data is in the system memory and the transaction logs. In the event of a crash, you lose the contents of the memory and all you are left with is the record in the transaction log. These transaction logs are crucial to the recovery of a failed Exchange server, whether it was a minor crash that required a reboot, or a more catastrophic failure requiring the deployment of your disaster recovery plans. The same goes for other transactions such as received messages, deleted items and messages moved to different folders. For this reason, it is recommended to house the transaction files on a redundant storage system, like a RAID 1 array, so that in the event of a hardware failure, no data is lost. Losing a set of transaction logs will not prevent you from restoring from your backups, but you will lose all the messages and changes since the last full backup.

Windows Server 2012 RTM coming in August

Yesterday at Microsoft’s Worldwide Partner Conference, the company announced officially that Windows 8 is on-track to reach the Release to Manufacturing (RTM) stage in the first week of August, with general availability to come later in October – essentially confirming many thoughts of the industry on when Windows 8 would be released.

There was no word at the event on when Windows Server 2012 would be released, but a post today on the Windows Server Blog reveals that the operating system will also RTM in the first week of August alongside Windows 8. General availability will be in September (earlier than Windows 8) through “multiple channels”.

The Release Preview of Windows Server 2012 has been downloaded over 500,000 times, according to the blog. Come September, it will definitely be interesting to see what differences there are between the shipping version of Server 2012 and the RP.

Windows Server 2012 SKUs

The official Windows Server 2012 page shows all four versions along with a brief description of each feature. The pricing ranges from $425 for Essentials up to $4.809 for the Datacenter SKU. One of the versions, Foundation, has no price listed, with Microsoft saying it is just for OEM businesses.


Windows Home Server is no more

Microsoft’s efforts to offer a version of Windows Server specifically for home server use have now changed. As revealed today in a new PDF FAQ document for the just announced Windows Server 2012 Essentials, the company announced it won’t continue to offer new versions of its Windows Home Server product.

In the PDF document, Microsoft states:

Windows Home Server has seen its greatest success in small office/home office (SOHO) environments and among the technology enthusiast community. For this reason, Microsoft is combining the features that were previously only found in Windows Home Server, such as support for DLNA-compliant devices and media streaming, into Windows Server 2012 Essentials and focusing our efforts into making Windows Server 2012 Essentials the ideal first server operating system for both small business and home use—offering an intuitive administration experience, elastic and resilient storage features with Storage Spaces, and robust data protection for the server and client computers.

The first version of Windows Home Server was launched in 2007. It was accompanied by server hardware made specifically for the operating system, including HP’s MediaSmart Home Server. However, the home PC server market never really caught on with the general public. The last major version of Windows Home Server was released in March 2011. runs on Windows Server 2012

With the recent announcement of the Windows Server 2012 Release Candidate (RC), we at considered how we might benefit from some of the operating system’s new features. is a cloud service that runs on thousands of computers spanning many datacenters across the globe. Performance is a key component in running a successful cloud service such as Bing. Bing serves thousands of user queries every second, and users demand both relevancy and speed in those results.
Our deployment of Windows Server 2012 leveraged four key new features, in particular:

  • Built-in Microsoft .NET Framework 4.5, included with Windows Server 2012, including the background garbage collection and associated improved latencies
  • Improved performance at startup, enabled by the multicore JIT functionality of .NET 4.5
  • Ability to collect call stacks for 64-bit .NET JITted applications
  • Evaluation of Hyper-V 3 (the version of Hyper-V in Window Server 2012)

Windows Server 8 – Deduplication

One of the long overdue features of Windows Server 8, is Data Deduplication. Deduplication can be enabled for NTFS volumes, and is part of the File Server role.
Deduplication works by examining the files on the disk, looking for duplicate files, once one is found the duplicate file will be referenced to the first file found. This means that two identical 1GB files, would only take up 1GB (The First File) + 4KB (The second file that points to the first file). This will intern allow us to store much more data onto a single disk.

Installing Deduplication –

The first step is to add the data deduplication role service; this is done in the new Server Manager and is a single step.


Once the role is installed, the next steps are to start the Data Deduplication Service (ddpsvc) and set it to Automatic startup. This is done in the normal services management snap-in. Then, each eligible volume needs to be configured for deduplication. Keep in mind that C:\ drives are not supported for NTFS deduplication, Configuring a volume for deduplication is done by right-clicking on the volume in Server Manager and selecting “Configure Deduplication”.


There are two primary options for deduplication, folder and file type exclusions. Those are configured in Server Manager when deduplication is configured. Microsoft don’t recommend deduplication certain file type such as; SQL Databases, VHD Files, Exchange Database. As this could result in a performance decrease. (Testing in a small lab, the performance decrease was unnoticeable.)


Top 5 SQL Server 2012 Features

Quite simply, SQL Server 2012 is going to revolutionize the way we think about availability and recovery. Today, when we think about these concepts, we consider an individual database (log shipping, replication, mirroring) or an entire SQL Server instance (failover clustering). In SQL Server 2012, in addition to Failover Clustering enhancements, we’ll be able to treat a group of databases as an entity – a much more common requirement with today’s complex, multi-database applications. This entity is called an Availability Group.
