The Basics of Data Backup and Recovery

Data backup and recovery have become one of the mandatory requirements for every organization and business. In this article, I’ll take you through the basics of data backup and recovery!

Technology has turned into a friendly companion for all of us in many sectors. One of the most crucial advantages of technological advancement is the accessibility of data. However, what if you are not able to access data? Just imagine if one day, when an enterprise doesn’t get access to the data, they need for critical business operations. It seems like a disastrous day for the business, doesn’t it?

Therefore, data backup and recovery become mandatory requirements in the present times where an organization’s data faces threats from different sources. However, enterprises are constantly troubled about finding the ideal backup and recovery solution according to their requirements. 

The following discussion would reflect on the definition of data backup and recovery alongside its significance. Furthermore, the discussion would extend beyond what is data backup and recovery and move towards the methods for backup and recovery.

However, the most important part of the discussion would focus on the top tools for backup and recovery. Readers could use the following guide to find out the ideal backup and disaster recovery solutions for enterprises.

What is Data Backup and Recovery?

The definition of data backup and recovery clearly establishes its exact objective. Backup and recovery refer to the process of backing up data in the event of a loss, alongside establishing systems that enable data recovery. The process of backup and recovery ensures the creation and storage of different copies of data that can safeguard organizations against data loss. It ensures the accessibility of data even in response to the deletion or corruption of data.

Therefore, data backup is ideal for disaster recovery, thereby becoming a significant component in data protection plans of an organization. However, all data backup and recovery methods don’t work for the recovery of all data and settings of a system. For example, database servers, computer clusters, and active directory servers could require additional disaster recovery methods for reconstituting their data and settings fully. 

Significance of Backup and Recovery of Data

The next crucial aspect in this discussion should be the importance of data backup and recovery. It can help in obtaining back critical data after primary data failure. Primary data failures generally happen due to hardware or software failure, a human-caused event, and data corruption. Backup copies help in restoring data from an earlier instance in time for helping the recovery of business from unprecedented events. 

Storage of the data copies on the different mediums is essential for effective data backup and recovery. The separate medium could be an external drive, a USB stick, or even a cloud storage container or a disk storage system. The separate medium could also be in the same location as the primary data or at another remote location. In addition, the consistent backup of primary data ensures minimal loss of data loss between the backups. 

The additional time between the backup copies increases the potential for data loss during recovery from a backup. The importance of backup and recovery is also evident in the retention of multiple copies of data. As a result, organizations can have the assurance and flexibility for the restoration of data from the point of time when the system is not affected by malicious attacks and data corruption. 

The following tasks in data backup and recovery clearly establish its efficiency in safeguarding the data of an organization. 

  • Planning and testing of responses to the different types of failures
  • Configuration of database environment for backup and recovery
  • Establishing a backup schedule
  • Monitoring of the backup and recovery apparatus
  • Troubleshooting backup problems
  • Recovery from data loss in the event of a disaster

Methods for Data Backup

Apart from the significance, readers should also focus on data backup and recovery methods. Here are the notable methods for backup and recovery that you can implement for safeguarding your data against loss. 

  • Disk or Tape Backup

The method of disk backup is one of the conventional backup methods. Disk or tape backup involves sequential backup of data on a physical device. Traditional disk or tape backups are considerably inexpensive, albeit presenting certain drawbacks. The setbacks include the efforts required for the management of physical tapes and slower backup and recovery times. Hard disks are advantageous than tapes because they provide data compression and deduplication. 

  • Hybrid Cloud Backup

The hybrid cloud backup method is one of the reliable methods for data backup and recovery. The method involves backup of data on a local device as well as a highly secure offsite data center. In addition, the machines should also have a backup on a local device, thereby avoiding concerns of downgrading machine performance. 

  • Direct-to-Cloud Backup

The direct-to-cloud backup method implies sending your data directly to the cloud without the need for backing up to a local device. Direct-to-cloud backup allows backing up of data in a remote data center without having a local copy. The internet speed and the specification of your machine determine the time required for backup.

Methods for Data Recovery 

Data recovery methods are also significant requirements for data backup and recovery. You can choose to recover from the local device only if you have backed up data on the device. Certain data backup and recovery tools help in the creation of a virtual machine from the device, thereby allowing users to carry out all business operations from the device.

The recovery from a local device is ideal for cases when you have experienced server failure or a security incident. Another notable method for data recovery involves recovery from the cloud. In this case, you have to use a solution that needs you to download backup data from the cloud. Users have to transfer gigabytes or terabytes of data through an Internet connection resulting in downtime. In case of damage in the local device, certain backup and recovery solutions can provide a virtual machine in the cloud. You can also assume this backup method as disaster recovery as a service (DRaaS). 

The two most common techniques for data recovery are logical and physical techniques for data recovery.

  • Physical Techniques of Data Recovery

Physical techniques of data recovery are ideal for situations involving hardware failure. As the name implies, physical techniques are relevant for physical damage to storage devices such as in cases of SD Card or hard disk failures. Modern storage devices such as hard drives are increasingly fragile and are vulnerable to physical damage.

In the case of physical techniques, users need a hard drive for storing recovered data and data recovery software for recovering the files. The data recovery software replicates the failed hard drive for obtaining data. After restoring data on the clone drive, users can reconstruct the data on the original drive. However, the use of physical methods for data recovery is not recommended due to the possibility of issues with the data even after the recovery process.

  • Logical Techniques of Data Recovery

The logical techniques for data recovery are ideal in cases involving software related errors. For example, if a corrupted hard drive restricts access to data, then users need logical data recovery. Some of the common errors that can create problems in data access are deleted partition, formatted hard disk, and damage to data files.

The logical method for data recovery involves taking the hard disk out of the device and placing it in another system in the read-only mode. Then, the data recovery software can read data from the hard disk and recover it. The logical technique for data recovery is also suitable for recovering data from SD cards, mobile devices, USB drives, as well as corrupt CDs, DVDs, and Blu-Ray Disks.
