LAN-Free backup in the Enterprise removes the Application server from the
The master backup server sends a list of files or records across the LAN
to the backup client.
The backup client translates the list into block addresses and sends the
block addresses to the media server. The media server is resident in
either a mount host or could be a server split out from an application
cluster for the duration of the backup window.
The media server then initiates a copy of the disk blocks to tape.
The media server, however, needs to have access to a consistent usable copy
of data. So for this function to work this way it will actually be supported in
conjunction with things like sub-system based snapshots, sub-system based
split mirrors or staged type data.
