A business should have a backup and disaster recovery plan so as to help secure data and the continuity of the business. Today, we live in a data-dependent world and the significance of backing up critical data and being able to keep working even during a disaster is very essential. Database Backup and Recovery refer to the strategies and procedures involved in protecting the database against loss and reconstructing database after any data loss. In this assignment, it describes database backup, disaster planning, and also highlights the important of integrating backup and disaster planning and the impact if both are not effectively executed.
Database backup
It is essential to back up all active databases regularly so as to guard against any of the data loss and also to protect the investment in the database design. When using a backup, it is possible to restore an entire database or even selected database objects. The backup tends to help in protecting the database from any of the system failures and also protecting against mistakes that the undo command may not be able to fix (Schin, 2014). The database backup refers to the process of backing up operational state and stored data of the database software. Backup of the database normally helps in the creation of duplicate instance or the copy of the database in case the main database crashes, gets lost, or is corrupted. It is a means of protecting and restoring the database. The backup is normally performed through the database replication and done for the database. The database administrators may be able to use the database backup copy in restoring the database to its operational state together with its logs and data.
The database backup is essential so as to ensure that the company complies with the business and the government regulations and also to ensure and maintain access to essential and critical business data in case of a technical outage or disaster. There are two types of backups that are physical and logical backups. The physical backup involves the creation of copies of critical physical database files. Physical backup is the copy of files storing the database information to other location whether offline storage like a tape or on a disk (Schin, 2014). The logical backup is the use of Oracle export utility in extracting specific data and storing the data to a binary export file. Logical backup involves reading the set of the database records and then writing them to the file. The physical backups tend to be faster than the logical because they tend to involve only copying of file without conversion. The logical backup tends to be slow than physical backup since the server should access database information and then convert it to logical format (Snedaker, 2013). In case the input is written on the client side, the server will need to send it to the backup program.
Disaster planning
Businesses whether large or small create and manage large volumes of information or data. Much of this data by the business is important, and some of the data is vital to the survival and continual operation of the business. The loss of the data from hardware failure, human error, malware or hacking can have a significant impact. Therefore, disaster planning is essential for the information. Disaster planning involves planning for business continuity in the event of a disaster that may destroy part or all of the business resources including data records, IT equipment, and the physical space of the organization (Auberry, 2015). The aim of disaster planning is to ensure that the organization resumes normal computing capabilities in as little time as possible. Disaster plan tends to describe how the organization will deal with the potential disaster. As the organization is ensuring disaster planning, it needs to have a disaster recovery plan. The disaster recovery plan tends to consist of precautions taken so as the effects of the disaster are minimized and the organization can maintain or quickly resume the mission-critical functions (Snedaker, 2013). Disaster planning involves the analysis of the business processes and the continuity needs and a focus on disaster prevention.
During disaster planning, it is important to develop the priorities and recovery time objectives for the information technology. The recovery strategies need to be developed so as to restore hardware, data, and applications in time so as to meet the needs of the business recovery. A disaster recovery plan can help the organization to be able to plan effectively for the disaster. The plan tends to document the procedures, actions, and policies to limit the disruption of the business in the wake of a disaster (Yage et al. 2015). As disaster is the event that makes the continuation of normal activities impossible, disaster planning involves actions that intend to minimize the negative effects of the disaster and allowing the organization to resume its functions. Organizations should ensure that they do have a disaster recovery plan because it is difficult to predict when a disaster will occur. With the disaster recovery plan, it provides a state of readiness, which allows timely response when the disaster happens. The significance of the plan is that it helps assess the damage, repair the damage, and also activate the repaired computer center.
Disaster planning is essential for the business in ensuring that the business is still able to continue operating even after a blackout, earthquake, or any other disruption. Disaster planning involves having a road map that will help in responding to some problems (Auberry, 2015). With a disaster plan, the organization tends to have a competitor edge in the case that a disaster occurs. A disaster plan is good for the organization since clients want to be sure that the organization is well prepared and will continue operating in case disaster strikes. When planning for a disaster, it is essential that the disaster recovery plan is well practiced so that they key players are familiar with the actions they will take in case a disaster occurs.
Integrating database backup and disaster planning
Organizations should make sure that they have a good disaster recovery plan and also backup plan so as to ensure that it can cope and also move forward when the worst happens. The database backup and disaster planning help in ensuring that the organization is ready to address any incident of a disaster (Mistry & Seenarine 2013). The integration of the database backup and disaster planning are essential in ensuring proper recovery for the organization. The integration of the two helps in minimizing the costly disruption of the business operations in the case of a disaster.
Although a backup is essential, a company must ensure that it has a disaster recovery plan so as to ensure full protection. It is important to integrate backup and disaster planning. Backing up without recovery is the same as not backing up at all; therefore, for the disaster recovery to be successful, it is significant to have an effective database backup. The integration of the backup and disaster planning tend to enhance the efficiency of the recovery in the case disaster strikes (Mistry & Seenarine 2013). Lack of integration of both of them can result in loss of vital data that will interrupt the organization’s operations. Without the integration of the disaster planning, the employees will not know how to recover the backed up data after the disaster. Integrating the two helps the employees to know what they need to do when a disaster occurs and how they should act so as to ensure the organization quickly resumes its operations.
Conclusion
Business owners tend to invest a tremendous amount of money, time, and resources to make their business successful. However, many of them fail to plan and prepare for disaster situations. Disaster planning and database backup are important because losing data tend to be a disaster by itself and may cause disastrous consequences when not restored at the right time. Disaster planning and database backup are essential for the organization as they provide techniques essential in protecting the business and ensuring that the organization resumes its operations as soon as possible.
