ELEMENTS OF LOTUS NOTES
There can be multiple synchronized copies, or replicas, of a single Notes application (.nsf file), on multiple servers or workstations. This lets users on various networks in a variety of places share the same information.
When you replicate, Lotus Notes updates the replicas, copying changes from one to the other, to make all replicas identical.
From the Replication page, you can also send outgoing Internet mail, receive POP mail, refresh the design of some applications, synchronize your local Contacts with a copy in your Mail, or check schedules in the Busy Time application.
For more information, see Using Notes applications offline and A guide to using the Replication page.
