A Backup Plan to Soften the Blow

A Backup Plan to Soften the Blow



Alan Hayward, Sales & Marketing Manager at SEH Technology


Technology has become an integral element of our daily lives. Despite the ever-increasing dependability of storage systems, digital data loss is all too typical. Human errors, software malfunctions (such as viruses), power outages, and hardware failures are all common reasons for the loss of files. A data breach could have catastrophic financial ramifications and 75% of small enterprises do not have a recovery strategy. Fortunately, data stored on a digital medium is virtually always recoverable. 

According to a recent survey, the average cost of downtime across all businesses is between $4,330 and $5,600. This figure is expected to climb as businesses become more reliant on technology. According to the survey, human error is the leading source of downtime, followed by hardware and software faults. 

As the reliance on technology rises, it is critical to discover strategies to limit downtime and the expenses that come with it. The following article defines data recovery and details the most frequent data loss issues and solutions. 


Data Recovery

Data recovery is the process of recovering information from a storage device that cannot be accessible in ordinary ways owing to previous deletion or damage to the digital medium. Various ways are utilised to recover the missing files, but only if the content is present someplace within a digital storage. None of the known restoration techniques can handle situations of permanent erasure, which happens when another file consumes its storage space; in such scenarios, the lost files can only be recovered from an external backup.

In general, there are two types of data recovery techniques: software-based and those that involve repairing or replacing damaged hardware components in a lab setting. In most situations, a software-based solution is used, which entails the employment of specialised utilities capable of interpreting the logical structure of the problematic storage, reading out the needed data, and delivering it to the user in a usable form for further copying. 

Physical repairs are carried out by specialists in the most severe cases, such as when some mechanical or electrical parts of the drive no longer function properly – in this case, all measures are aimed at a one-time extraction of the critical content, with no possibility of continuing to use the affected device.


Data Loss

In general, the total effectiveness of a data recovery operation is strongly dependent on the selection of the appropriate retrieval technique and its timely use. That is why it is critical to understand the nature of each loss incidence and what may be solved in each circumstance. In contrast, incorrect acts might result in the irrevocable deletion of data. Hardware/system failure (31%), human error (29%), and viruses and ransomware (29%) are the most prevalent reasons for data loss.

When removing a file, each file system behaves differently. The primary goal of file deletion is to free up storage space required by the file for the storage of a new file. Storage space is not instantly erased for performance reasons; therefore the real file content remains on the disc until this storage space is utilised for storing a new file.

Unintentionally, file system formatting can occur. The formatting operation establishes empty file system structures on the storage device and then overwrites any existing data. If the new and old file system types are the same, it destroys the current file system structures by overwriting them with new ones; if the types are different, the structures are written in separate places, which may delete the user’s files.

Modern file systems provide a high level of security against internal mistakes but are frequently rendered ineffective against hardware or software failures. Even a tiny amount of incorrect content sent to the wrong location on storage can destroy file system structures, break file system object linkages, and render the file system unreadable. This problem can develop due to blackouts or hardware issues.

When information regarding a partition is lost, this failure can occur due to a failed disk operation or user mistake, resulting in the loss of information regarding the location and size of a partition. If a RAID system fails, restoration is feasible without the missing drive as RAID redundancy allows recovering the content of a failed component.


Backup Plan

Human error continues to be more common than data destruction caused by natural or man-made disasters or criminal activity such as ransomware attacks. On the other hand, organisations should be prepared for any data loss that might impair important business applications or activities, regardless of the cause. A complete backup and recovery solution should be in place to secure all data worth protecting, regardless of where it sits.

This includes physical servers on-premises and virtual or cloud-hosted servers, which may require frequent or continuous backup, storage area networks (SANs) and various forms of shared storage, which can contain storage for blocks, objects, and files. It also includes endpoint devices including desktop and laptop computers, workstations, and tablet and mobile devices. Individual hard discs will need to be restored for these kinds of devices.

Data recovery is a critical IT responsibility. Backups, according to IT specialists, are the last line of protection. A business’s capability to leverage various technologies and services differentiates it. A thorough disaster plan is required to maintain company continuity and minimise disruptions to services. 90% of organisations incorporate data integrity and backups in their disaster recovery strategies.
