Abstract

In a computer network system, a user-defined file modification request is communicated to a primary server, which communicates the request to a secondary server. The file modification request is saved in a non-volatile storage media associated with the primary server, and the file modification request is executed and saved in a non-volatile storage media associated with the secondary server.

Claims

1. A real time backup system comprising:

at least one primary server having a non-volatile storage media where a file modification request for a file modification is saved;

at least one secondary server for executing said file modification request, each secondary server having a non-volatile storage media where said file modification is saved; and

a communication means for communicating said file modification request from said at least one primary server to said at least one secondary server.

2. A method for real time backup comprising the steps of:

saving a file modification request for a file modification on at least one non-volatile storage media associated with at least one primary server;

executing said file modification request on at least one secondary server, each secondary server having a non-volatile storage media;

saving said file modification on said non-volatile storage media associated with said at least one secondary server; and

communicating said file modification request from said at least one primary server to said at least one secondary server.
