Doing the work of a dedicated IT team, Windows Home Server can automatically back up 10 computers, and restore them entirely if any should fail. You can quickly retrieve individual files or folders from previous backups, in case you accidently deleted or lost them.
Article: Using Windows Home Server to Back Up Windows Small Business Client Computers
This Microsoft article offers great information regarding how to use Windows Home Server in your Small Office/Home Office.
Windows Home Server sits behind your firewall and has strong password controls to help secure your network. Plus, with network health monitoring, it will tell you the exact condition of any computer on your network in real-time.
Centralize your data
Using Windows Home Server, you can easily manage all your data in one place, freely accessible by all the computers on your network and securely shared with others you trust outside your business.
In the office, simply click on Share Folders to access all your materials. Or, if you’re on the road, browse to your free custom URL (for example, https://contoso.homeserver.com) to quickly search and find your files.
Grow your storage as your business grows
Windows Home Server makes it easy to add more storage space. Simply add an internal or external hard drive and Windows Home Server will take care of the rest—to your business it will appear as a single repository for all your important files.
When you connect multiple hard drives, a duplicate copy of your important files will be saved for added protection. If one hard drive fails, you can simply restore the data mirrored on another hard drive—it's RAID made simple.
Access your work from virtually anywhere
Windows Home Server includes Internet Information Services (IIS), which allows secure access to your files via the web. This makes it easy to get your important information from outside of your office, through your securely protected personal website.
With a Remote Desktop Connection you can access your server from anywhere, as well as any computer connected to it. This means you can remotely control your computers from anywhere you are, allowing you the freedom to define where you work from.*
For more sophisticated small businesses that plan on growing, Windows Small Business Server 2008 adds additional business functionality and scales well beyond 10 users.
*You may need to add services from your broadband provider to use the Windows Home Server remote access features. For example, you will need certain "ports" to be open to use these features. Some broadband providers block certain ports for customers on some service plans. Also, some broadband providers' terms of service may limit or prohibit setting up and running of "servers" on their networks by some customers on some service plans. Make sure that your use of Windows Home Server features follows your broadband providers' terms of service. Please contact your broadband provider if you have questions about their terms of service.
**To connect to one of your home computers via Remote Access, your home computer needs to be properly configured and running one of the following operating systems: Windows Vista Ultimate, Windows Vista Business, Windows Vista Enterprise, Windows XP Professional with Service Pack 2 (SP2), Windows XP Media Center Edition 2005, or Windows XP Tablet Edition with SP2.
