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.

Note:

If you are protecting an entire server, your repository server must have a same or newer operating system than the source (not including service pack level). For example, you cannot protect a Windows 2008 source to a Windows 2003 repository server. This is because the repository server must be able to process the source's registry for system state processing.

Windows Server 2008 Datacenter, Enterprise, Standard, Essential Business Server, Web Server, Foundation Server, Small Business Server, or Storage Server Edition
Windows Server 2003 or 2003 R2 Datacenter, Enterprise, Standard, Web Edition, Small Business Server, or Storage Server Edition. Each of the Windows 2003 operating systems require Service Pack 1 or later.
Architecture—32-bit and 64-bit architectures are supported
File system—Double-Take Backup 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.

Architecture	Minimum System Memory	Recommended System Memory
32-bit	128 MB	At least 1024 MB
64-bit	512 MB	At least 2048 MB

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 Backup 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.
Disk space for system state image—This is the amount of disk space on the repository server to hold the image of the source system state. You should have at least 5 GB of space on the repository server for the system state. The more applications you are running on the source, the larger the system state image will be. Therefore, you may need additional space if you source has many applications. If your repository server is protecting multiple sources, you will need space for each source's system state.
Server name—Double-Take Backup 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—Version 3.5 Service Pack 1 is required on the repository server.
