In addition to the repository server requirements , the following requirements apply to the
TimeData continuous data protection functionality of Storage Mirroring Replicate.
●
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—NTFS is the only supported file system. Do no use FATx file
systems on the repository server.

Architecture Minimum System Memory Recommended System Memory
32-bit 1 GB 2 GB
64-bit 2 GB 4 GB
●
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—This is the amount of disk space,
approximately two and a half times the amount of data being protected for each
source, needed on the repository server to hold the TimeData continuous data
protection historical data. You may need to adjust the amount of disk space
needed based on the applications and data on your source, the number of days of
historical data you choose to store, and the change rate of your data. There is a
combined limit of 2 TB of TimeData historical data for all sources that you are
protecting to the repository server.

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.
