What are sites and how does replication work?

Refer to the following topics for more information:
Sites and replication partners
A site is a

database with one or more

s attached to that database. Replication enables data to be duplicated between databases on separate sites so that both databases contain the same information. If one database fails, you can manage each site by using the information on the database from the second site.
A replication partner is an individual management server within the second site, or remote site. A site may have as many replication partners as needed. Each partner 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 in 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 management servers, but the database they use and the way in which they communicate is different:
  • Replication partners can use either the default database (Microsoft SQL Server Express in 14.3 RU1) or a Microsoft SQL Server database. The management servers do not share the database. All replication partners share a common license key. If you use the Microsoft SQL Server database, you can connect multiple management servers that share one database. Only one of the management servers needs to be set up as a replication partner.
  • Site partners share a single Microsoft SQL Server database.
How does replication work?
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.
After replication occurs, the database on site 1 and the database on site 2 are the same. Only computer identification information for the servers differs.
For more information on how often to replicate, see the following article:

Determining the size of the replication server
A replication partner requires a larger database than a single management server installation. The increased size requirements for the replication server include the following factors:
  • Number of managed clients
  • Client installation package sizes retained in the database
  • Number of log files retained
  • Database maintenance settings
  • Log size and expiration timeframes
  • Definition update sizes
  • Database backup information requirements
In general, the hard disk requirements for the replication server should be at least three times the hard disk space used by the original Symantec Endpoint Protection Manager for the initial replication.
