Requirements


Source server requirements This is the server that contains the data you will be protecting.

• Operating system—The source 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 Server, Small Business Server, or Storage Server Edition. Each of the Windows 2003 operating systems require Service Pack 1 or later.

Double-Take for Hyper-V host level protection cannot protect Windows Server 2008 R1 cluster.

• 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.
  • 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 source to hold the Double-Take RecoverNow program files.
• Server name—Double-Take RecoverNow includes Unicode file system support, but your server name must be in ASCIIformat.
• Network protocols—Your servers must use TCP/IP with static IPaddressing.
• Microsoft .NET Framework—Microsoft .NET Framework version 3.5 Service Pack 1 is required on the source. 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.
• Junction points—Only domain controller junction points will be replicated. Any user-created junction points will be replicated as two unlinked copies of the data.
• Application-consistent snapshots—If you are protecting a server that has SQL Server installed and you want to take application-consistent snapshots, you must be using SQL Server 2005 or 2008. The application consistency feature does not support SQL Server 2000.

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 ASCIIformat.
• 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 IPaddressing.
• 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.

TimeData (CDP) requirements In addition to the repository server requirements, the following requirements apply to the TimeData continuous data protection feature.

• Operating system—If your repository server is running a Windows 2003 operating system, you must have Service Pack 2 installed on the server.
• File system—NTFSis the only supported file system. Do no use FATx file systems on the repository server.
• System memory—The minimum system memory requirements for the repository server are higher with TimeData continuous data protection.
  • i386 operating systems—The minimum system memory is 512 MB. The recommended system memory is at least 2GB.
  • x64 operating systems—The minimum system memory is 512 MB. The recommended system memory is at least 4GB.
• Disk space for program files—This is the amount of disk space, approximately 1.5 GB, needed on the repository server to hold the TimeData program files.
• Disk space for TimeData historical data—There is a 2 TB limit of protected data per TimeData storage bin. Since the storage bin can store approximately two to two and a half times the amount of data being protected for each source, you can maintain approximately 4 to 5 TB of historical point-in-time data. You may need to adjust your TimeData configuration based on the applications and data on your source, the number of days of historical data you want to store, and the change rate of your data.
• Microsoft Installer—Microsoft Installer version 4.5 or later is required.
• Microsoft Internet Information Services—Microsoft IISversion 5.0 or later is required on the repository server. This must be installed prior to installing TimeData.
• Microsoft ASP.NET—The version of Microsoft ASP.NET included with your Windows operating system is required on the repository server. This must be installed prior to installing TimeData.
• Microsoft SQL Server—TimeData will automatically install Microsoft SQLServer Express or Standard, depending on your Double-Take RecoverNow media (CD or web download).
• Drive configuration—For best results using TimeData continuous data protection, you should separate the operating system, SQL Server, the TimeData drive, Event log, and Event cache on different drives.
