Abstract

A method and system for securely backing up and restoring a Secure Redundant Computing Node (SRCN) in a secure network without using removable media is disclosed. Further, the method and system stores a copy of a backup file of the SRCN in another SRCN paired to the SRCN within the secure network.

A Method and System for Secure Backup of a Secure Computing Node without using a Removable Media

In the prior art, a remote system of a non-secure network is used for storing a backup file of a Secure Redundant Computing Node (SRCN) in a secure network. The backup process using the remote system for storing the backup file is illustrated in fig. 1.

Figure 1

The remote system can be responsible for creating backup files for all secure redundant computing nodes in the secure network. The backup file thereby generated is subsequently stored in an external removable media. In the first step
of the current backup process, the remote system triggers a SRCN primary system, depicted as System A, in fig. 1, to create the backup file by sending a command to the SRCN primary system. Thereafter, upon receiving the command, the backup file containing all modifications to data since a previous installation, is created at the SRCN primary system. This step may also involve applying a digital signature to the backup file and, packaging the backup file. Subsequently, the backup file generated is sent for storage in a hard drive of the remote system upon receipt of a command from the remote system. The remote system thereafter transfers the backup file to the external removable media, and sends a command back to the SRCN primary system indicating that the backup process has been successfully completed.

The current restore process for restoring the SRCN primary node depicted as System A in another SRCN node, depicted as System B, using the remote system is depicted below in fig. 2.

Figure 2

In the process for restoring System A in System B, a base code is loaded into a hard drive of System B using read-only media. Subsequent to loading the base code, the external removable media containing the backup file is removed from the remote system. Thereafter, the external removable media is inserted into System B after

which a user selects the backup file to be used in the external removable media for

restoration. The backup file selected is copied into the hard drive of System B. Thereafter the backup file is extracted, and the digital signature of the backup file is validated. If the validation is successful, the backup file is used to restore System A in System B.

As can be seen, the current backup process and the current restore process requires the use of the remote system and the external removable media situated outside the secure environment which can lead to security issues.

Disclosed is a method and system for securely backing up and restoring a SRCN by storing a copy of a backup file of the SRCN in another SRCN paired to the SRCN

within the secure network.
