Storage Mirroring Replicate overview
Storage Mirroring Replicate is a comprehensive disk-to-disk backup and recovery
solution. It allows you to protect a production server, known as a source, by replicating
data from the source or an image of the entire source to another server, known as a
repository server. The repository server can be located locally or over a WAN. The
image of an entire source contains all of the source server's data and the source server's
system state, which is the server's configured operating system and the installed
applications. The data or entire server image can be recovered to a dissimilar physical
or virtual environment.
As changes are made on the source, Storage Mirroring Replicate mirroring and
replication keeps the image of the source stored on the repository server up-to-date.
Storage Mirroring Replicate replicates, in real-time, only the file changes rather than
copying entire files, allowing you to more efficiently use resources.
In the event the source should fail, you can use the image of the source, stored on the
repository server, to quickly and easily create a new source, which can be a physical or
virtual machine.
