Understanding Deduplication and Single Instance Storage

January 25th, 2012 by

The new Workstation Backup Appliance is a Windows based NAS with a removable drive that includes software to backup windows and Mac workstations.  One of the key features in this product is file level deduplication.  This feature was written for Highly Reliable Systems by Microsoft and is referred to by them as Single Instance Storage. Single-instance storage is a system’s ability to keep one copy of content that multiple users or computers share. It is a means to eliminate data duplication and to increase efficiency. SIS is frequently implemented in file systemse-mail server software, data backup and other storage-related solutions.

In the case of the WBA this means that if you have multiple Windows 7 machines that have the same files (for example in the \windows operating system folder) the WBA backs these files up only once.  So the backup drive(s) can be much smaller than the sum of the machines backed up. This functionality applies to the Microsoft workstation backup storage on the WBA, not for general NAS shares.  This appliance can could be used to backup both workstations and servers assuming you have enough space on the 2TB internal drive.  The way this is achieved is by using Microsoft built-in backup software  for the workstations and 3rd party software for the server backup. if you share a folder for server backup be aware that deduplication won’t apply to that data.

Slow Backup? Try ShadowProtect

January 20th, 2012 by

One of the most common problems we hear is that a full backup takes longer than one night to complete (The slow backup problem).  Here at Highly Reliable Systems, we’ve tested a variety of backup software and have found that imaging based products (as opposed to file based) provide the best backup performance.  A product like StorageCraft’s Shadowprotect will do a block level copy of every occupied sector of your disk, providing the best backup speed and smaller backup windows.  The product now supports virtualization, meaning they have special licensing for protecting multiple Virtual machines running on a single piece of hardware.  This article discusses the virtualization  options:


In addition to using block level imaging, products like Shadowprotect allow the  use of incremental backups that can be periodically rolled up into a single image file (often referred to as synthetic backup).  This overcomes the old concern of having to restore from multiple tapes or files and verifies data integrity in a single file.
