Cloud vs. Local Storage: How to Properly Backup Data?

Are you deciding between cloud and local storage for data backup? We compared both solutions, their advantages and disadvantages, and practical tips on securing your data. Learn which option fits your needs and how to set up a backup system that protects your important files from loss and cyber threats.

Cloud vs. Local Storage: How to Properly Backup Data?

Each of us generates a massive amount of data today - from work files and photos to personal documents. But what if something goes wrong? Where to store data so we don't lose it? We'll look at the advantages and disadvantages of both cloud and local storage and advise you on how to solve backup in a way that's convenient and secure for you.

What are cloud and local storage?

You can easily imagine cloud storage as a virtual space somewhere on remote servers, which you access via the internet. Therefore, the files in the cloud are not physically with you, but you can access them from any device. 

Well-known providers include Google Drive, Dropbox, or iCloud, which take care of the storage and protection of your data. Conversely, local storage consists of physical drives, like USB flash drives, external drives, or NAS servers. You have the data directly with you. The plus is that you can access them even when the internet goes down.

Advantages of cloud storage

One of the main advantages of the cloud is that you have access to data from anywhere and anytime, as long as you're online. Cloud storage also allows you to set up automatic data synchronization – files update themselves without you having to worry about anything. Another plus is flexibility. If you run out of space, you just buy more storage.

On the other hand, being in the cloud means being completely dependent on internet connectivity. Besides, you have to pay regular fees, which are not exactly low. Security can also be an issue. Every now and then, data leaks or losses occur.

Advantages of local storage

If you want to have your data fully under control, local storage is ideal for you. You can work with data offline and don't have to worry about monthly fees – you pay for an external drive once, and it serves you for years. Another advantage is quick access, especially if you work with larger files or multimedia data.

However, it's necessary to take care of the physical protection of the devices. External drives or USB flash drives are prone to damage or loss. Also, keep in mind that managing multiple drives can be challenging if you have a large amount of data.

How to choose the right storage for you?

Regular users often use the cloud because it offers easy sharing of photos and documents within family or friends. However, we recommend occasionally backing up to an external drive – the cloud is excellent for data accessibility, but local backup adds assurance in case of downtime or loss of account access. 

In rare cases, some data may be lost – such an issue occurred with Google in the past. Companies might consider a combination of cloud and local storage. They can keep sensitive data locally while storing regular office tasks or remote work data in the cloud. This also simplifies data sharing among colleagues.

Data security both in the cloud and locally

Whether you use the cloud or local drives, always ensure proper data security. For cloud services, choose a strong password and enable two-factor authentication. Trusted services encrypt data, reducing the risk of leakage during transfer and storage.

For local storage, use encryption, such as with VeraCrypt or BitLocker, especially if storing sensitive data. If you use a security program, remember to update it regularly. To ensure your backup system is always ready, set up regular backup checks. For example, try restoring several files and verify they work correctly. 

We personally recommend backing up according to the 3-2-1 rule – having three copies of the data, two on different storage types, and one offsite. For local storage, it's also important to occasionally transfer data to newer devices, as external drives can fail over time.

Which cloud platforms to choose?

When choosing a cloud platform, it depends on your specific needs. Google Drive is ideal for regular document sharing, while Dropbox is great for team collaboration where version history is important. 

If you use Windows, OneDrive will be a suitable choice as it's well-integrated with Microsoft's office tools. For company backups requiring high security, Amazon S3 or Azure can also be considered as alternatives.

Cloud services often have a basic free version (e.g., Google Drive offers 15 GB). However, if you need more space, the price depends on the provider and capacity – for instance, 100 GB on Google Drive costs around 50 CZK per month. Local storage, like external drives, starts at around 1,500 CZK for 1 TB. A network storage (NAS) might be more expensive, but companies and advanced users often can't do without them.

As you have seen, both cloud and local storages have their pros and cons. If you don't work with data often, local storage will suffice. Conversely, for freelancers, companies, or even students, it's better to opt for the cloud. The best choice, however, is to combine both options, ensuring you truly won't lose your data.

The lack of computational power hinders the development of artificial intelligence. OpenAI faces challenges in developing new products such as an improved ChatGPT with visual recognition and new versions of DALL-E and Sora. The increasing complexity of AI models requires enormous computational capacity, which slows down innovation and the launch of new features on the market.

Streaming platforms are experiencing a massive boom, changing the way gamers and viewers perceive the gaming world. With the rise of cloud gaming, augmented and virtual reality, and ever-expanding monetization opportunities, gaming and streaming are becoming more than just a hobby. Discover what lies ahead for game streaming in the coming years.
