Organisational Backup IT professionals argue that simply backing up data does not ensure data protection and security. Hence, mere copying important/ relevant data on electronic digital devices such as CD-R and DVD is not enough. Organisations need to have a multilayered approach to data backups. Once important data has been saved on to a storage device, it is essential to make a hard copy and keep it in a safe location – usually away from the office surroundings. Important data such as employee records, marketing strategies, SWOT analysis and profit and loss graphs need to be backed up on other portable electronic equipment which is common throughout the organisation. In other words, backups in organisations need to follow two dimensions of organisational backups and departmental backups. The presence of two backups ensures that long-term and short- term goals of the overall organisation are protected. Thus, data backups are intricately tied up with the concept of data security. The design of a structured secure organisational backup system is built around three layers of control systems: Data access controls: These controls protect the confidentiality and integrity of sensitive or critical data backups. Administrative access controls: They ensure that only authorised individuals have access to the backup infrastructure. Physical access controls: These include physical security measures of swipe card systems and locks for data backup protection. Continuous Data Protection (CDP) Organisation Backup Most organisations tend to rely on disk-based backup systems to ensure unified organisational backup. It is described as a multi-faceted backup system which protects data ensuring constant backup and upgradation with data tracking and access controls. Features: Continuous backup Tracks data copying it from tape to disk enabling constant and quick data recovery Aims to provide secure data backup minimising data loss Continuous data monitoring for latest data backups. This has been incorporated in CDP to preserve copies of all prior versions of the data. The user has the ability to view and access these prior data versions as required/ needed. This CDP tool also shortens data backup and recovery time from hours or days to seconds or minutes. This, consequently, removes the obstacle of a backup window. CDP is defined as a methodology of disk-based backup and replication systems The business value of CDP lies in its function to control data corruptions and interruptions CDP backup systems can be classified into two categories: file-centric unified organisation backup and block-based departmental backup CDP system removes the requirement for tape drive and media handling at the remote site CDP hardware appliances are expensive costing more than 50, 000 pounds CDP software functions with every server and network and costs less – simple, cost-effective and practical Personal Backup Methods PC users deploy the easy and fast data backup method of online backup. Online backups ensure data safety against man-made and natural disasters of theft, fire, flood or power surge. However, online backups are unreliable and prone to data corruption. Online backups do not ensure data privacy. But, online backups reduce the threat of data loss to a large extent. The reliability and safety of online backups basically depend on the reputation of the network provider. Online backups expose the user making him or her vulnerable to the public eye. Private and vital data is backed up in the public arena. Hence, an individual user has to be highly sure of the network provider. The individual user can only back up data files using a high-speed Internet connection for online backups. Data Backup Software Usually, backup operations are inbuilt within the computer. All backup applications and software are installed on your PC. These could include incremental backups which allow for one complete data backup at one time or packaged tools which can be bought from a vendor. Danz Retrospect Backup Professional is a low-cost data backup software tool costing less than 65 pounds. It allows for data backup including data safety tools and multiple backup files. Veritas and Computer Associates is another packaged data backup application which boasts of complete data protection Managed backup solutions such as DataFort or ImperaData have the ability to back up data across the Internet.
