What is Local Backup?

The Importance of Local Backup in Secure Cybersecurity: Protecting Business Data & Minimizing Downtime

Local backup holds a pivotal role as it serves as the primary line of defense to ensure against data losses attributed to a variety of threats such as, malware attacks, unintentional data deletion, system crashes, hard drive failures and the like. It refers to the practice of storing important data and information in a geographical location that is proximate to the original data source- often within the same building or network. Local backups provide quick and painless recoverability which makes them an absolute must-have tool for orchestrating business continuity plans in the modern digital landscape.

When we talk about greatest security threats in today’s interconnected world, we are referencing much more than just viruses. We are referring to a whole variety of malicious software, known collectively as malware. Malware encompasses any piece of software that is engineered specifically to harm or exploit any computing device or network. As businesses are becoming exceedingly dependent on digital data, malware has arguably become one of the foremost threats to businesses of all sizes, across industries. In light of that, data protection mechanisms, such as local backups, are being viewed as a cybersecurity measure that is indispensable, as they can restore compromised or lost data to Its original state.

The process of creating a local backup involves making a copy of the data onto another storage device such as an external hard drive, network attached storage (NAS), or a tape system. The main advantage of local backup lies in its accessibility and recovery speed. Recovering lost data from a local backup is much faster when compared to cloud backups as it doesn't require a fast and reliable internet connection. This speed can prove vital in minimizing downtime after a cybersecurity incident.

While local backup is an important piece of a comprehensive data protection strategy, it is critical to understand its limitations as well. As the backup resides in the same geographical location as the original data source, it is susceptible to the same physical threats such as fire, flooding, burglary, or natural disasters. Therefore, backups that are stored onsite should be secured physically, and a secondary backup at a remote location should also be considered.

The local backup systems can doubly serve as potential access points for hackers; that’s when antivirus protection kicks in. Antivirus systems protect the key access points in a computer against malware threats, thus safeguarding both the original data and the locally stored backups. If a local backup solution does not have adequate security measures in place, quite paradoxically, instead of serving as a life vest, a local backup can potentially become the Achilles' heel of an entire organization's data security. Therefore, while having an antivirus system is indeed beneficial, real protection should include both an antivirus system and a backup system.

To ensure the utmost state of security, local backups must also be supplemented with encryption technologies too. With the help of modern encryption standards, data stored on local backup systems can be rendered useless without the correct decryption key. That means that as long as the key is kept secure, then the encrypted data would remain inaccessible to hackers, providing an added layer of security.

The significance of local backups in the scope of cybersecurity and antivirus cannot be overstated. As the threats to the data continue to evolve, so should our approach in safeguarding it. As with all things pertaining to successful cybersecurity, diversity is key. A judicious blend of cybersecurity gear, which includes but is not limited to, local backups, encryption technology, and antivirus software provides a multi-layered, comprehensive, defense strategy vowed to tackle modern digital threats. Ignoring the above could place an entity in a precarious position, to say the least.
