Backup functionality is now moved to a specialized server and modularized
architecture. The three components of a traditional LAN-based backup
environment include:
A master backup server that maintains schedules and data catalogues
for the entire enterprise and controls the copy of data to backup media.
Media servers that copy data to backup media at the direction of a
master backup server.
Backup clients—computers with data to back up.
