Hello All.. I am preparing a home office setup for a friend. Its going to be 10 Desktops-All Windows 7 Pro (32bit). Basic 24-port switch. Internet will be through a router. I proposed data backup as the data is most critical for any business. So, here's my plan: 1. image backup of all PCs as they come with windows 7 pre installed on it (Factory defaults) 2. Then I will setup all software needed, all configurations/setup, antivirus installed. One more image at this point for all computers. 3. All users will save data to a network location. 4. For this, do i need a dedicated file server? Is there any alternative? 5. I want this storage to be RAID for data redundancy. (Total requirement up to 4TB) 6. How can i implement this in cost effective way as this is for a home office scenario. we are on tight budget.
