Host backup is a host-based backup and a traditional data backup technology. In this backup architecture, the tape read-write device is directly connected to the application server that needs to back up data, and provides data backup service for the server. The advantages of host-based backup architecture are simple backup management and fast data transmission. The disadvantage is that it is not conducive to the enjoyment of the backup system, and it is not suitable for the data backup needs of large information systems that need to back up multiple servers.

LAN backup is based on LAN-based backup architecture, and data transmission is based on network. Configure a server as a backup server in the LAN, and the backup server is responsible for managing the backup tasks of the whole system. Tape reading and writing equipment can be connected to a server (called a media server), and multiple application servers that need to back up data will transfer the data to the tape library through the local area network to realize backup. ?

The so-called LAN-free backup refers to the data backup method that releases network resources. LAN-free backup system is a new architecture based on data storage network.
