Abstract

A computer unit with excellent backup function is realized. A backup operation system is set, and based on the setting, a data file under editing or the like is saved in a backup section. The backup operation system is distinguished through existence of execution of a backup operation, execution timing of the backup operation, an object to be backed up, a backup destination, and the like. This prevents data loss in the case where a computer unit is hanged, or in the case where trouble of the computer unit, crash of a terminal side data storage section, or the like occurs.

Claims

1. A computer system comprising a server and a computer terminal, the server and the computer terminal being connected for communication with each other,

wherein the computer terminal comprises:

a data processor for processing a data file;

input means for selecting one of a plurality of external backup operations;

a storage period specifying part for specifying a storage period of backup data for at least one predetermined one of the selected external backup operations;

a communication part for communicating with the server; and

a controller for executing the selected external backup operation to cause the communication part to transmit the data file processed by the data processor as the backup data and storage period information indicating the storage period specified by the storage period specifying part to the server; and

wherein the server comprises;

a receiver for receiving the data file as the backup data transmitted from the communication part; and

a storage unit for storing the data file received by the receiver.

2. A computer system according to claim 1, wherein the server further comprises a storage period control part for controlling the storage unit so that the backup data are saved in the storage unit during the storage period indicated by the storage period information received by the receiver.

3. A computer terminal connected to a server for communication, comprising:

a data processor for processing a data file;

input means for selecting one of a plurality of external backup operations;

a storage period specifying part for specifying a storage period of backup data for at least one predetermined one of the selected external backup operations;

a communication part for communicating with the server; and

a controller for executing the selected external backup operation to cause the communication part to transmit the data file processed by the data processor as the backup data and storage period information indicating the storage period specified by the storage period specifying part to the server.
