Recovering after a failure
If your source experiences a failure, such as a power, network, or disk failure, your target machine will
stand in for the source while you resolve the source machine issues. During the source machine downtime,
data is updated on the target machine. When your source machine is ready to come back online, the
data is no longer current and must be updated with the new data on the target machine.
Before you begin to restore to the original source, resolve the issue(s) that caused the failure.
The recovery steps are different depending on the type of failure that occurred. If the source server has to
be rebuilt, follow the instructions in ”Rebuilding the source” on page 14. If the server is just offline due to
non-disk related issues (such as network problems issues or power failure) and you do not need to rebuild
your server, follow the instructions in ”Recovering to the original source” on page 17.
Rebuilding the source
1. Install Windows on the source, if necessary, configuring it as a Windows 200x member server with a
unique name and IP address. If you need to rebuild your source using the same server name, see
”Appendix 2: Alternate recovery method” on page 24.
2. Apply any Windows 200x service packs or patches.
3. Temporarily, disconnect the target server from the network. At this time, users will no longer be able to
access Exchange.
