TimeData requirements
In addition to the repository server requirements, the following requirements apply to the
TimeData continuous data protection feature.
l Operating system—If your repository server is running a Windows 2003 operating
system, you must have Service Pack 2 installed on the server.
l File system—NTFSis the only supported file system. Do no use FATx file
systems on the repository server.
l System memory—The minimum system memory requirements for the repository
server are higher with TimeData continuous data protection.
l i386 operating systems—The minimum system memory is 1 GB. The
recommended system memory is at least 2GB.
l x64 operating systems—The minimum system memory is 2 GB. The
recommended system memory is at least 4GB.
l 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.
l 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.
l Microsoft Installer—Microsoft Installer version 4.5 or later is required.
l Microsoft Internet Information Services—Microsoft IISversion 5.0 or later is
required on the repository server. This must be installed prior to installing
TimeData.
l 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.
l Microsoft SQL Server—TimeData will automatically install Microsoft SQLServer
Express or Standard, depending on your Storage Mirroring Replicate media (CD or
web download).
l 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.
