log shipping (n)~ Copying at regular intervals log backup from a read-write database (the primary database) to one or more remote server instances (secondary servers). Each secondary server has a read-only database called a secondary database that was created by restoring a full backup of the primary database without recovery. The secondary server restores each copied log backup to the secondary database. The secondary servers are warm standbys for the primary server.
