Having backups is essential for our day to day. It is the way to protect our data and files and thus avoid losing them in the event of a problem. We already know that some types of threats such as ransomware can put all our files at risk. Thanks to this type of functions we can avoid greater evils. Now, are cloud copies secure? We explain some reasons why you should not trust everything on this type of platform.
Cloud backups are not always reliable
As we have mentioned it is very important to create backup copies . We can protect our files and prevent data loss if we are victims of a ransomware attack. We already know that this type of threat aims to encrypt our files and make it impossible for users to access them.
Fortunately, when creating backup copies, we can make a backup of all those files that have been blocked. However we can make backups on physical devices and also in the cloud. This last option is interesting because it has functions such as automation or being able to access data anywhere. Now, are cloud backups secure? Logically everything that is exposed on the Internet has a higher risk.
Everything on the Internet can be exposed
The first is what we discussed earlier. Any information, data, files that we have on the Internet may be exposed at any time. We cannot control in the same way a backup that we have on a physical disk that we have in the cloud.
It is true that security measures are getting better and better, but there can always be problems that expose this stored data.
Ransomware attacks cloud backups
Ransomware is one of the biggest threats to our files today. We have seen that they can encrypt the files that we have on our systems and later ask for a ransom in return. However, backups can save us from certain problems.
The thing is, there are varieties of ransomware that directly attack cloud backups. They can thus jeopardize our security. Therefore we can say that copies in the cloud can suffer problems due to this type of malware.
There may be vulnerabilities in the platforms
Another problem that may be present is that of vulnerabilities in the platforms that we use. There are many services that offer us the possibility of storing backup copies. Now, as in any tool, software or platform, there can always be security problems.
Therefore, vulnerabilities in the platforms we use to host our backups can also be a problem. We have seen cases where files have been exposed due to service failures. Logically these errors are fixed as soon as they are known, so we must always keep the updates and patches that are available.
The data is not always encrypted
One last problem is that the data we store is not always encrypted. This will depend a lot on the service we are using. Some are more focused on privacy and security and encrypt all the content we store. Others, on the other hand, do not have all the necessary measures for this.
Our advice is that those sensitive files that we want to back up in the cloud, such as personal data for example, upload them encrypted. We have a large number of encryption tools at our disposal. In this way we will ensure that our data will be correctly encrypted and safe from possible problems.
In short, we can say that backups are very useful for storing our files. However, it must be borne in mind that they are not 100% safe and certain precautions must be taken.
