replication

database, networking Creating and maintaining a duplicate

copy of a database or file system on a different computer,

typically a server. The term usually implies the

intelligent copying of parts of the source database which have

changed since the last replication with the destination.

Replication may be one-way or two-way. Two-way replication is

much more complicated because of the possibility that a

replicated object may have been updated differently in the two

locations in which case some method is needed to reconcile the

different versions.

For example, Lotus Notes can automatically distribute

document databases across telecommunications networks. Notes

supports a wide range of network protocols including X25

and Internet TCP/IP.
