A replication server requires a larger database than a single-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, you should expect the hard disk requirements for the replication server to be at least three times the hard disk space used by the original Symantec Endpoint Protection Manager for the initial replication.
