1. Discuss a Backup and Restore product for either the Workstation or the Server.

answer

1. Introduction

The product is being developed as part of the Google Summer of Code with the mentoring organisation being The Linux Foundation, specifically within the scope of the Ceph File System. It is essential that as a part of this project, features are developed in a generic manner in order to have the possibility of application outside of the Ceph environment.

This is where a 3rd party application is required, in the past Linux users have been left without such an application, the recent emergence of enterprise environments using Linux and unstructured data now requires a suitable backup and restore product. This product should be scalable across all possible use cases, from SOHO (Small Office/Home Office) users with a single PC, to an enterprise with many servers and large amounts of data. The aim for the product is to also be suitable for a wide audience with an easy installation process and minimal configuration.

Before introducing the product that has been developed, it is important to understand part of the basis behind its creation. Critically for all PC and server users is the task of continual backup and restore for data protection and disaster recovery. Many users rely on OS specific tools, which in the event of an OS failure may prove useless in recovering data or require a tedious data recovery process.

1.1. Purpose of the Backup and Restore Product

This wide range of restore needs requires a backup and restore product that is flexible and has the ability to restore anything from a single file to an entire system.

Finally, the user may simply wish to recover a document that was deleted by mistake. This could require sophisticated search and retrieve options to recover the lost document and ensure that the current version of the document is not overwritten.

Another scenario is when a user encounters a problem with some new software that causes it to become unstable. In this case, the only way to restore the system to its previous state may be to restore it to a point in time before the new software was installed. This requires what is known as a system restore utility and the availability of a snapshot of the system at that point in time.

The user may wish to restore an entire system after a disaster, such as a system crash or hardware failure. The user could find it very time consuming and costly to reinstall an operating system and reconfigure a system to its previous state. This is especially true in large organizations with many systems, where the loss of one or several systems could be disastrous.

Although the purpose of a backup and restore product may seem somewhat obvious, there are actually many reasons why a user requires the facilities that such a product delivers. It is not simply a case of making a copy of files so that they can be retrieved at a later time. In fact, the process and the reasons behind it are much more complex.

1.2. Importance of Backup and Restore in Workstation/Server Environments

Nowadays, data is the most valuable asset for an organization. Data loss can cause the organization to lose millions of dollars. The more dependent a company is on its data, the more crucial it is to have a reliable backup system for workstation/server environments. The workstation/server environment is the most vulnerable place for data to be corrupted. The workstation is the place where end users work on the documents which are stored on the server. With constant connectivity to the server, whatever data is saved will be immediately updated to the server. This is good for real-time access but bad if a virus corrupts the document. A virus attack on the server will not only affect the document that is currently being worked on but the entire document inside the server. Usually, the server is the place where end users will store all the safer copies of the documents, so when data on the server is corrupted or lost, the impact is equivalent to losing workstation and server data. Server data loss can occur due to hardware failure, software corruption, virus attacks, etc. With today’s fast-paced growth of technology, software becomes obsolete in a short amount of time, thus creating data in new software that becomes useless because the new software has also been corrupted due to system restore. With all of these possibilities of data loss in workstation/server environments, the importance of having a reliable backup and restore product is immense. When the data loss has occurred, the best way to restore the data is to time travel it to the point where the data was last known to be good. By doing this, it will prevent possible further data loss due to trying to repair the corrupted data. This can only be done if the backup has a good cataloging system and can backup/restore data in a granular mode. The cataloging is important when the administrator or end user is trying to restore the data if a new system has been set up and the backup is located on a media. He or she must be able to identify the data and location so the backup can be mounted and the data can be restored using the data found in the catalog. Usually, if the data is mission-critical, the administrator that is restoring the data will need to make sure that the server data must be reformatted and a clean OS installation is done. Duplication of the previous OS setup can be done using a system restore by restoring the data to a dummy location, and it will ensure that no mistake is made when using the data at the original location. The backed-up data can then be moved to the original place, overwriting some new data that has been created. A good backup and restore product will have all these features and can ensure that it can restore the data to its original state.
