In a CDP deployment, data is constantly being replicated to the specified backup computer. The backup computer can be on the same LAN or in any remote location. CDP performs continuous backup for any number of primary servers using just one central server as the backup repository. CDP can perform one-to-one backup and uses negligible bandwidth.
The source system has the live data in use, and the backup system has a mirror of the source system data. CDP provides flexible disaster recovery options. It can be configured to provide failover to a second server or it can maintain a mirror copy and make it available to perform a restore to the original location or the original server. You can also use CDP to restore single files.
In a remote server deployment, the source system data is constantly mirrored to the server that is located off-site. If the source system breaks, then another Agent, which can be cohosted on the computer running the Server, provides alternate access to the files. (When a CDP/slave Job is accessed on a computer running the Server, you cannot manage passwords. You can manage passwords on any other Agent connected to the Job.)
If the source fails, it is possible to deploy a new Agent anywhere quickly, including on the same LAN where the original Agent is. Name the new Agent the same name as the failed one and users will automatically redirect, or you can use DFS to automatically failover.
