Kindly share this post

Are you confident that your valuable data is protected from unexpected disasters or cyber threats? Consider this: 1 in 10 computers fall victim to viruses, and a staggering 113 phones are stolen every minute every day[1].

With data loss being a sudden and potentially irretrievable nightmare, ensuring reliable backups is non-negotiable. March 31st, celebrated as World Backup Day, is a poignant reminder of this essential task. Let’s delve into the common backup mistakes people make and how to steer clear of those.

1. Skipping regular backups:

The most common mistake is forgetting to back up data regularly. Whether personal files or crucial business documents, not establishing a consistent backup routine leaves you vulnerable to data loss.

Unexpected system crashes or malware attacks can happen anytime, making your precious data inaccessible or permanently lost. But you can help avoid such a situation by setting up automatic backups.

2. Putting all faith in a single backup device:

A device can get damaged or stolen, putting your backups at risk, so depending entirely on one storage medium is playing a dangerous game with your data’s safety.

 Instead, diversify your backup storage solutions with a combination of external HDDs, NAS, and cloud storage.

Portable HDDs like those from WD like Western Digital’s My Passport offer up to 5TB for simple, cost-effective backups. For smartphones, 2-in-1 flash drives such as SanDisk Ultra Dual Drive Go USB Type-C and SanDisk iXpand Flash Drive Luxe are convenient options.

These drives, compatible with USB Type-C devices, automatically back up photos, videos, and more. Just plug and play for seamless data transfer across devices.

If you need a device to store huge amounts of data, then the desktop drive called My Book  from WD is just the product for you, with up to 22TB of storage capacity.

3. Forgetting version control:

Overlooking version control during backups is another blunder. Not keeping multiple versions of files increases the chance of saving corrupted or wrong data over previous versions.

Without a proper versioning system, fixing mistakes or retrieving older versions can become a challenge. To prevent forgetting version control, establish a system that tracks changes to your files over time.

This ensures that you can always revert to earlier versions if needed, helping protect against accidental data loss or corruption.

Regularly maintaining this system will help you stay organized and prepared for any unforeseen issues.

Additionally, it’s crucial to verify the version you’re backing up to ensure it’s the correct one.

This simple step can help prevent accidental overwriting of important data with potentially corrupted or incorrect versions.

Double-checking ensures that you’re safeguarding the most up-to-date and accurate information, minimizing the risk of errors during backups.

4. Ignoring off-site backup solutions:

Many people overlook off-site backup solutions, assuming local backups are foolproof. However, relying solely on local backups makes you vulnerable to site-specific disasters like fires or theft.

Using off-site backups means keeping copies of your data in different places so that if something bad happens in one area, your data stays safe.

As an alternative, you could use cloud storage. Cloud backup devices are popular for remote data storage accessible via the internet. Various online cloud services offer features like file synchronization, sharing, and encryption for secure data storage.

5. Underestimating encryption:

Not prioritizing encryption in backups can be a costly mistake. Storing unencrypted backups makes your sensitive data vulnerable to unauthorized access or breaches.

Implementing strong encryption ensures even if your backups fall into the wrong hands, the data remains protected.

However, it is equally important to remember not to opt for out-of-the-box encryption solutions, as they might make it difficult for you to retrieve the backed-up information later.

My Passport HDD and My Book from WD come equipped with built-in 256-bit AES hardware encryption with password protection that helps keep content secure.

Additionally, maintaining proper key management practices is essential to ensure smooth decryption and access to your data when needed.

This World Backup Day, Western Digital urges you to back up your data safely, and at the same time, prepare for the unexpected by having a contingency plan in place for device mishaps like crashes, theft, or damage.

Worrying about losing data isn’t something you have to lose sleep over if you have an active data backup strategy.

A common rule of thumb for keeping important data from disappearing forever is the 3-2-1 Rule. It dictates that you should:

3. Have THREE copies of your data. One is a primary backup and two are copies.

   2. Save copies of your backups on TWO different types of media or devices.

   1. ONE backup copy should be kept offsite in case of disaster.

Determine where and how you’ll store backup files and identify support contacts for swift assistance.

These proactive measures ensure quick data recovery and safeguard your cherished memories for the long haul.

Telcos Resume SIM Card Sales after 2-Week Halt

Telecommunications operators have resumed full SIM swap and related services following a four-week nationwide outage linked to the National Identity Management Commission (NIMC)’s migration to a new verification platform.

Telcos Resume SIM Card Sales after 2-Week Halt

The outage rendered millions of subscribers unable to perform SIM-related tasks such as swaps, replacements, and activations.

Operators in the industry say the disruption began on June 26, 2025 when telcos temporarily halted SIM registrations and swaps due to unforeseen technical challenges during the transition to NIMC’s upgraded identity verification system.

The migration was mandated to enhance the integrity and efficiency of national identity management but caused major service interruptions across all Nigerian networks.

However, July 21, both MTN and Airtel confirmed via their social media handles that SIM swap services have now fully resumed.

MTN announced: “SIM swaps have now resumed. We can confirm that NIMC services are fully operational and appreciate their support in the migration to a new platform for NIN verification services for the telecommunications industry.

In a public update issued via its MTN Nigeria Support handle on X (formerly Twitter), MTN confirmed that SIM swaps have now resumed.

Telecom operators complained that the portal was unreliable or inaccessible, which resulted in the suspension of SIM swaps, number porting, and new SIM registrations, even though NIMC maintained that the platform was operating as intended.

Unexpected technical difficulties arose during the switch to the new platform, according to the Association of Licensed Telecommunications Operators of Nigeria.

Real-time NIN verification for SIM registration, replacement, and network migration was impacted by these issues.

“Unexpected technical difficulties have surfaced, impacting real-time NIN verification for SIM registration, replacement, and porting, following a recent directive from the National Identity Management Commission mandating Mobile Network Operators to transit to a new identity verification platform,” ALTON stated in a previous joint statement signed by Gbenga Adebayo, chairman, and Damian Udeh, publicity secretary.

Nigeria, Others Achieve 84% Adult Mobile Phones Penetration

Published

The World Bank has affirmed that 84 per cent of adults in low-and middle-income economies, including Nigeria, own personal mobile phones.

The bank in its Global Findex 2025 report said mobile phone ownership was widespread and nearly everywhere. It said data from the Global Findex 2025 Digital Connectivity Tracker, revealed that “86 per cent of adults worldwide, and 84 per cent of adults in low- and middle-income economies, own personal mobile phones.”

The report pointed out that mobile phones and the internet had become widespread and essential to daily life in every economy around the world.

A earlier overview had indicated that Nigeria had a high mobile phone penetration rate, with estimates around 85 per cent to 87 per cent in 2024.

This translates to over 200 million mobile connections, making Nigeria a leading market in Africa for mobile phone ownership and usage. While the overall penetration is high, there’s a growing trend towards smartphone adoption, with forecasts predicting over 140 million smartphone users by 2025.

According to DataReporter, a total of 150 million cellular mobile connections were active in Nigeria in early 2025, with this figure equivalent to 64.0 per cent of the total population.

However, note that some of these connections may only include services such as voice and SMS, and some may not include access to the internet.

There were 107 million individuals using the internet in Nigeria at the start of 2025, when online penetration stood at 45.4 percent. Nigeria was home to 38.7 million social media user identities in January 2025, equating to 16.4 percent of the total population.

These headline stats offer a great overview of the “state of digital” in Nigeria at the start of 2025, but in order to make sense of how digital trends and behaviours have been evolving over time, we need to dig deeper into the data.

According to the World Bank, “as of 2024, individual ownership of mobile phones reached 86 per cent of adults worldwide.

“For many people, barely an hour goes by without their using a mobile device to make a call, ext a friend, read the news, access business information, post a meme on social media, pay for something, play a game, engage with a colleague or a customer, or search for information.

“As access to and use of digitally connected technologies increase, people, businesses, and governments place an increasingly high priority on online interactions. “Digitally connected technologies have clear, well-documented benefits.”

It further highlighted that access to mobile phones and the internet was associated with reduced poverty, increased consumption, and more employment for individuals in lowand middle-income economies.

“Women also experience these benefits, as internet access enables access to flexible jobs3 and has been shown to increase female labor force participation. “Mobile phones also facilitate information sharing.

For instance, in agricultural contexts, farmers’ access to real-time prices and buyer demand data can inform their decisions on where to sell, enhancing market efficiency and reducing the distances they would otherwise travel to get the best return for their product and time.

“Internet access also helps create jobs and aids individuals and countries in exporting goods and services,” it added. The World Bank further noted that owning a mobile phone furthermore enabled financial access through mobile money and other mobile financial services.

It added that these financial accounts and services, typically offered by mobile network operators or fintech firms and accessed via networks of local agents, were associated with lower rates of poverty, increased consumption and savings,and greater resilience to economic shocks.
