Backup Exec 2012 Deduplication VS Windows Server 2012 Deduplication
January 31, 2013 5 Comments
Please note that Backup Exec 2012 is currently UNSUPPORTED on Windows Server 2012
I was curious about how the Backup Exec 2012 deduplication functionality would work under Windows Server 2012, so I setup a couple of servers to test this out.
On my Backup server, I created 2 drives and configured Backup Exec disk storage for both of them, 1 with standard disk storage, and the other with Deduplicaiton disk storage.
I then installed the Backup Exec 2012 remote agent for Windows on a Windows Server 2012 server and configured two jobs. One going to Disk storage 0001, and one going to Deduplication disk storage 0001.
The files that I will be backing up total to 13.9 GB, the files are purposely duplicated otherwise this would all be pointless.
The Backup Exec Results
Once both backup jobs had completed I compared the amount of space used in each folder, first by the folder properties in Windows and then with the backup job properties.
Here we can see the duplication ratio of 1.8:1 or 55.6% (I used this site to convert to a percentage)
The Windows 2012 Deduplication Results
On the server that I have been backing up, I created a new drive and configured it for Windows 2012 deduplication. I then copied all the files over to this drive, and let the deduplication run its course.
Coming back the next day, I checked the progress on the drive and found that the dedup stats where in!
As you can see, the SavingsRate is 55% and the OptimizedFilesSavingsRate is 56%. I’d say that the 55.6% of Backup Exec Deduplication sits comfortably in the middle of the savings rates in Windows.
While obviously you would these 2 deduplication options in different circumstances, its good to know that the savings being afforded to you are extremely close. I think this is also a good example of how good the deduplication technology in Backup Exec 2012 really is.
