This paper covers a research on data backup, data recovery and disaster planning. It gives a detailed coverage of what data backup is, the importance of backing up data, types of data backups, and the various types of backup devices. Additionally, it explains disaster recovery and disaster planning in detail. Data backup is the process of creating coverage for electronic data in the computer system. Electronic data is prone to adversities that can lead to data loss. Hence, it is important that data is backed up all the time to avoid information loss. Data could be backed up into disk or tape devices. Additionally, backup hard drives and cloud backup could also be used to prevent one from losing data completely in case of any adversity. There are different types of data backups. They include incremental data backup, full data backup, differential data backup, and mirror backup. On the other hand, data recovery is the process of trying to retrieve and repair lost data. There are a number of techniques that are used to recover data. Some of these techniques include hardware replacement, file restoration, disk imaging, and data carving. Disaster planning involves backing up data in backup devices, like tapes and disks. People should take great care of any bit of their information to avoid losing it. The only way to the safety of data is through reliable backups.

Data Backup and Recovery
With continuous daily changes in the world brought about by technological developments, organizations, companies, and individuals gladly embrace technology. Unlike the past when associations and individuals stored data in files and used other primitive methods, data is now being stored electronically. However, the electronic method of storing data has its disadvantages. Computers, laptops, and mobile phones are prone to adversities. It endangers the ability of such electronic data to provide information when needed. Some of the disasters that electronic data storage faces include viruses, accidental deletion or corruption, theft, physical calamities, and device crushing. All these disasters lead to loss of information. Trying torecover lost data is hectic. Moreover, information may be not recovered at all. Thus, it is paramount that people do data backup to avoid losing useful data, by facilitating its easy retrieval (Howard, 2006)
There are a number of backup strategies in existence. One of the strategies is to employ the simplest backups. One of the easiest ways is the use of a USB drive. The drive is plugged into one’s computer, and the backup starts immediately after that. With this device, the hardware is conversant with what it is performing. Hence, no installation of software takes place (Crandall, 2013).
The other backup strategy is that one should be ever ready for any disaster. In such a way, the backup system is in its place when a disaster strikes. One more backup strategy is to store items for the long haul. It involves archiving of data. Additionally, having a backup copy is necessary. It guarantees almost full protection and recovery (Crandall, 2013).
Types of Data Backup
In backing up data, it is imperative that one makes right decisions regarding the types of data backups to use. There are four major types of data backups. One of them is the full backup type. The full data backup entails the storage of all data chosen from the folders, which are to be backed up. It is the best type of data backup since it is the fastest in data return, compared with other types of data backup. However, because of its slow nature in backing up data, it is not used by many people. Additionally, its storage space is large. It requires a lot of disks and tapes (Fleishman, 2009).
Data recovery is the process of trying to retrieve and refurbish lost data. However, the invention of software for recovery is never a guarantee that the recovery of any lost data is possible. Sometimes, information can be lost forever. Hence, it calls for the implementation of serious measures to protect information from complete loss. There are several techniques of data recovery. However, the process of recovering lost data is dependent on certain considerations. They include the situation that led to data loss, the data revival software used inn generating the backup, and the backup target device. All these considerations influence the choice of the data recovery method. One could use a single technique or try different (Bang, Lee, Lee, & Lee, 2013; Eddy, 2013).
One of the methods of data recovery is hardware replacement. It is a procedure where a part of the computer might have been destroyed, hence leading to data loss. Thus, the mere replacement of a destroyed part is enough to recover lost data. For example, a fan has stopped working, thus exposing the hard drive to excess heat and break down as a result. The hardware replacement technique is cheap, simple, and fast in data recovery. The other procedure for obtaining lost data is disk imaging. It is a technique that is applicable when a hard drive has suffered from physical damage. It involves elevating information from the damaged hard drive to a stable one. It circumvents the operating system (OS) directly into the hard drive. This fact endangers the OS as it is not a reliable process (Fleishman, 2009).
Disaster planning revolves around data backups. Data backup is the only reliable way of planning for any disaster. Disasters could be as follows: physical damage to the hard drive, accidental deletion, virus attack, and calamities, such as floods, earthquakes, and tornadoes that cause havoc and may result in damage to electronic devices. The only sure way of staying protected is by backing up data. However, there are several backup devices. The backup tools include tapes and disks. These devices are used to store data. Such devices should never be stored together and with the hard drive (Crandall, 2013).
Data backup is vital to any business. Loss of data can be costly to both an individual and the organization. Even though data recovery processes have been put in place, the recovery and repair of lost data is never a guarantee. Therefore, people need to embrace the initiative of backing up data to avoid complete loss of data in case of any unfortunate circumstance. Additionally, one needs to guard information against corruption. Given various data backup options to choose from, one should take up the option that suits them well.
