Due to the complexity, implementation of a classic backup system is today seldom executed. Systems of such type are smoothly connected with archiving and replication systems, SAN, fast snapshot mechanisms or, finally, with HSM/ILM type systems. Also, far-reaching changes may be observed in hardware, starting with classic systems made up of a server, software, and tape space. Very often, implementations also comprise complete SANs, disk arrays with replication mechanisms, server clusters, and tape silos with various characteristics drivers, and specialised data storage devices (e.g. filers).
