You wake up one morning and you cannot access your cloud storage account. What is there in your cloud storage account? Photos, documents, tax returns, important memos, family pictures – and now you just realized that you lost them all.

Either someone hacked your account or you accidentally deleted something and missed the recovery period. Maybe you decided to trust one service and ended up with an inactive one.

It may sound scary, but such problems occur every day, and almost every person makes similar mistakes. The great thing is that most data loss is avoidable. Once you learn about common errors that people make while using cloud storage services, you will be able to protect your precious files.

Storing All the Files in One Cloud Service

Most people believe that once they choose one cloud storage service and sign up, all their files are secure. The reality is harsher. Every cloud service experiences outages and even cyberattacks. Every provider may also make changes that you were not aware of before.

This does not mean that you have to register with several cloud services at once. Just make sure to back up your files in another location, such as:

- An external drive (updated once a month)

- Another cloud storage account

- A combination of both

Choosing Easy Passwords and Not Using 2FA

Let's face it – most people choose passwords that are too easy to break. Usually, they choose passwords that are easy to remember, but they are also easy for hackers to guess. Using such passwords for your cloud storage may be a huge risk since anyone can access your files if you do not use additional security measures.

Here are some recommendations to ensure your data security:

- Use a password manager that generates strong and unique passwords for every website.

- Never use the same password for different websites and applications.

- Enable two-factor authentication immediately after signing up for your cloud storage account.

2FA is one of the best protection methods available for cloud storage since even if someone steals your password, they still cannot access your account without your smartphone, security key, or authenticator app. 2FA works on all major cloud storage platforms, but not everyone uses it.

Sharing Files Without Being Aware of the Permissions

Once you want to share a document with a friend, you click on "Create Share Link" It may seem like it is okay to share files this way, but it creates many vulnerabilities. For example, the link may be used by anyone who knows it. Anyone with the link will be able to share it further, or search engines may index it.

Even more, if you give "Everyone Can Edit" permissions to your shared folders, anyone with the link will be able to delete or change files. There have been many cases of people deleting or changing file contents simply because it was easy to do.

Here is what you should do instead:

- Always select the "Viewer Only" option if you just need to share a document or picture.

- Set an expiration date for your share links so they expire after a certain period.

- Whenever possible, use email-based sharing because it limits access to specific people.

- Regularly review who has access to your shared folders and remove people who no longer need it.

Syncing Incorrect Folders to Your Device

It may seem like a useful function, but it can also create serious risks. If you sync a folder containing sensitive information to your laptop, it means that any hacker who gains access to the device may also gain access to your cloud storage. The more devices you sync with cloud storage, the greater the risk.

Be careful when syncing files to your devices and sync only what is necessary. Files containing sensitive information, such as tax documents, agreements, and bank statements, should be uploaded and downloaded manually whenever needed.

Ignoring Storage Space Limits and Being Caught Off Guard

Free cloud storage accounts have a limited amount of storage. Dropbox provides 2 GB of storage space, Google Drive provides 15 GB, and OneDrive provides 5 GB. It seems like enough until you exceed the limit.

Some services will not let you upload new files once you reach the limit. Others may stop syncing files altogether. As a result, you may end up with different versions of the same file across your devices.

What is even worse is that if you exceed the storage limit and do not react, some services may automatically delete newly uploaded files. You may lose recently uploaded photos and other important documents.

It is recommended to check your storage usage once a month. If you are approaching the limit, delete unnecessary files or upgrade to a plan with more storage capacity.

Using Your Personal Cloud Storage for Keeping Important Files

Maybe it sounds weird, but people often use their personal cloud storage accounts to keep documents that require additional security measures. For example, people store tax forms, medical records, Social Security numbers, passwords, and other sensitive information.

They believe that a password is enough to protect these files, but personal accounts are not as secure as enterprise-focused solutions.

Think carefully about whether cloud storage is the best place for such important documents. It may be safer to use a password-protected external hard drive and keep it in a safe or safety deposit box.

Documents that need to be accessed regularly can be stored using dedicated encrypted storage solutions such as Proton Drive or password management tools.

In any case, never keep lists of passwords or financial account numbers in a regular cloud storage folder. It is like storing your house keys under the doormat.

Forgetting About the Provider's Data Recovery Policy

Here is something that surprises many people: the recovery window. If you accidentally delete a file, how long will your provider keep it in the trash? Google Drive keeps deleted files for 30 days, while Dropbox stores them for up to 180 days for paid users. Other services may keep deleted files for a much shorter period.

The situation becomes even more complicated if a hacker gains access to your account and deletes everything. Some companies may restore your account to its previous state, but the process varies significantly between providers.

Always read the data recovery policy before you start using a cloud storage service. Find out what happens if you—or someone else—delete everything tomorrow and how much time you have to recover your files.

Not Updating Your Applications and Software Regularly

Cloud storage providers release updates regularly. These updates usually contain important security patches that fix known vulnerabilities. If you are not updating your software, you are using outdated versions with known security flaws. Attackers actively exploit these weaknesses because they know many people never update.

Make sure automatic updates are enabled for all your applications. Do not leave it to chance. Your cloud storage app, operating system, browser, and other software should always be updated because security threats constantly evolve.

Moving Forward with Confidence

There is no need to become a security expert to protect your files. You simply need to develop good habits and make sure your actions are intentional. Choose strong passwords, enable 2FA, configure your sharing settings, keep multiple backups, and always know your cloud storage provider's data recovery policy.

Your files are valuable. They include years of memories, important documents, creative work, and information that took time to collect. Protect them.

Start with something small today. It can be enabling 2FA or creating an additional backup location. Continue with another security measure next week. After a month, you will have taken enough precautions to stop worrying about losing everything.
