Repository server requirements

This is the server that will be protecting your source server(s).

Operating system—The repository server can be a physical or virtual server running any of the following operating system editions.
- Windows Server 2008 or 2008 R2 Datacenter, Enterprise (x86, x64), Standard (x86, x64), Web Server, Foundation Server, Small Business Server, or Storage Server Edition
- Windows Server 2003 or 2003 R2 Datacenter, Enterprise (x86, x64), Standard (x86, x64), Web Edition, Small Business Server, or Storage Server Edition. Each of the Windows 2003 operating systems require Service Pack 1 or later.
If you are protecting an entire server, the repository server must have the same or newer operating system. For example, you cannot have Windows 2008 on the source and Windows 2003 on the target. The two servers do not have to have the same level of service pack or hotfix, however the R2 release is considered a different operating system. For example, you cannot have Windows 2008 R2 on the source and Windows 2008 on the target. The Windows edition (Standard, Enterprise, and so on) does not have to be the same.
Architecture—32-bit and 64-bit architectures are supported.
File system—Double-Take RecoverNow supports the same file system formats that Microsoft supports: FAT, FAT32, and NTFS.
System memory—There are different memory requirements depending on the system architecture you are using. Be sure you have at least the minimum amount of memory for your environment. You should consider having at least the recommended amount of system memory, especially if your repository server is protecting multiple source servers.

i386 operating systems—The minimum system memory is 1 GB.
x64 operating systems—The minimum system memory is 1 GB. The recommended system memory is at least 2 GB.

Disk space for program files—This is the amount of disk space, approximately 130 MB, needed on the repository server to hold the Double-Take RecoverNow program files.
Disk space for data files—This is the amount of disk space on the repository server to hold all of the source data files. This will be dependent on the number of sources you are protecting, the applications you are running on each source, and the amount of data files on each source.
Server name—Double-Take RecoverNow includes Unicode file system support, but your server name must be in ASCII format.
Mount point limitations—You cannot store your source data or source image on the repository server on a volume that is accessed by a mount point.
Network protocols—Your servers must use TCP/IP with static IP addressing.
Microsoft .NET Framework—Microsoft .NET Framework version 3.5 Service Pack 1 is required on the repository server. This version is not included in the .NET version 4.0 release. Therefore, even if you have .NET version 4.0 installed, you will also need version 3.5.1. You can install this version from the Double-Take RecoverNow CD, via a web connection during the Double-Take RecoverNow installation, or from a copy you have obtained manually from the Microsoft web site.
Cloud support—You can use Double-Take Cloud with Double-Take RecoverNow to protect your source to a repository server in the cloud. See the Double-Take Cloud web site for more details.
