Exclusion versus Inclusion

  • [アーティクル]

Windows Home Server was desiged to automate the backups of home computers running Windows XP and Windows Vista.  The goal behind the design was to ideally ask zero questions, and  be incredibly space efficient in how much hard disk space is needed for all of these backups.

When people install the Windows Home Server Connector software on a home computer, that computer will be configured to backup its hard drive(s) to the home server every night.  You can fine tune the backup settings for a given PC by using the Windows Home Server Console application.  The fine tuning is based on an "Exclusion" model - so that you can exclude entire hard drives or select specific folders to exclude.  You can also fine tune when the backups of your home PCs are done each day via the Settings in the home server console.

The reason for using an "Exclusion" model is two-fold. 

  1. Windows Home Server is designed so you can completely restore a PC, including the operating system, applications, and data from a backup stored on your home server. 
  2. The technology the team developed for storing the backups of your home computers on your home server is incredibily space efficient.  Some people have even dared to call it "smart" on the forums.  In that the home server only stores each unique cluster (think of it as a Lego block, if you aren't familiar with 'clusters') it finds on a PC only once on the home server.  And then the home server keeps track of which PC had which "Lego" blocks on a given date & time.  If you dig under the covers, it is rather amazing how much your home PCs have in common.

Backup solutions that ask users to select what they want to backup (i.e. "The Inclusion Method) offer too many choices and often times people find they forgot to include an important folder when they try to restore something. Ouch !

Once you understand how Windows Home Server Automated Backup works, you will realize that "exclusion" is the way to go.

    Hi, I was unable to reply in the relevant blog post but from what I see WOL is a very popular request. I have developed an add in for WOL. You can find more details here: http://forums.microsoft.com/WindowsHomeServer/ShowPost.aspx?PostID=1545562&SiteID=50

    Even though I'm not at the product team, and don't know anything about it, I'll guess that there will never be a mac client, but again, it's just a guess

    I'd like to second what HowardScott said about a Mac client.  With the current trend of Apple gaining ground in the overall consumer PC market, providing Mac users with the option of still using Home Server just like they do with their Windows-based computers would help to ensure that all potential customers could benefit from the features Home Server has to offer. Mac support would definately be a major selling point for me, as my wife and I both own Windows and Mac systems.

    The exclusion model is fine - it just needs to be easier to exclude multiple folders in one fell swoop (i.e. checkboxes) - the current method takes far too long if you want to exclude more than a couple of directories.

    Hi.  Exclusion is a good feature, and it's good to be able to pick and choose what to backup (I, for example, would not want to backup the OS). But, what I could really do with, is a client for the Mac, as I, like many others I suspect, run a home with several PCs and Macs. Are we likely to ever see a mac client? Thanks
