Replication enables data to be duplicated between databases one separate sites so that both databases contain the same information. If one database fails, you can manage the entire site by using the information on the database from another site.
A partner is a management server on another site with a different database and management servers. A site may have as many partners as needed. Each partner, or remote site, connects to the main site or local site, which is the site that you are logged on to. All sites that are set up as partners are considered to be on the same site farm.
Each site you replicate data with is either a replication partner or a site partner. Both replication partners and site partners use multiple servers, but the database they use and the way they communicate is different:
All sites typically have the same type of database. However, you can set up replication between one site that has an embedded database and a second site that has a Microsoft SQL Server database. If you use an embedded database, you can only connect one Symantec Endpoint Protection Manager. If you use the Microsoft SQL Server, you can connect multiple management servers or share one database. Only the first management server needs to be set up as a replication partner.
The changes that you make on any partner are duplicated to all other partners. For example, you may want to set up one site at your main office (site 1) and a second site (site 2). Site 2 is a partner to site 1. The databases on site 1 and site 2 are reconciled by using the replication schedule. If a change is made on site 1, it automatically appears on site 2 after replication occurs. If a change is made on site 2, it automatically appears on site 1 after replication occurs. You can also install a third site (site 3) that can replicate data from either site 1 or site 2.
Figure: How replication works between the main site and two remote sites illustrates how replication of data occurs from the main site to two other sites.
