I need to learn more about these two concepts and the technologies used to support them. Database replication provides a fast and reliable way to spread information to multiple locations in a distributed business environment, letting systems move data closer to mobile users and remote offices. Distributing data is usually done across a network of workstations, servers and even mainframe systems. Organizations distribute applications from central corporate offices to regional and off-site locations. Mirroring is the creation and maintenance of an identical twin.
Any file can take advantage of mirroring.
The process uses two partitions on different drives connected to the same disk drive controller. All data on the primary partition is mirrored automatically onto the secondary partition. Thus, if the primary drive fails, no data is lost. Instead, the partition on the secondary disk drive is used. Mirroring is not only restricted to a partition identical to the primary partition in size and number of tracks, but it also eliminates the problem of acquiring an identical model drive to replace a failed drive when an entire disk drive's data content is being mirrored.
