Cloud services are one of the hottest trends when it comes to IT and business. But it’s a new form of technology. And this means it comes loaded with risk.

The headlines regarding the boom in cloud computing have been plentiful and the future remains bright. Therefore, it’s an area of IT that your organization has to get on board with. After all, the benefits associated with the cloud are numerous. And they have the capacity to transform your organization into a stronger, more functional and more competitive business. So, it sounds pretty enticing, right?

But migrating your services to the cloud is a big step. There are many risks and factors to take into consideration. And that’s why we’ve put together this guide on how to avoid cloud migration risks.

What are the Risks?

There are a number of risks to consider when migrating to the cloud and these include:

  • Unauthorized Use of Services: One of the major risks of cloud computing is that cloud service providers allow additional services to be installed by default. And this is down to the self-service nature of the cloud. Therefore, employees with access with the cloud have the option to install unauthorized software. And this could soon led to malware being installed. 
  • Increase in Complexity: The complexity of the cloud can have a major impact on your IT resources. IT staff will be required to learn an entire new model of IT, so this will add extra strain to their workload. Perhaps most concerning is the lack of knowledge regarding cloud security. This weakness in security could pose a massive threat to your network. 
  • Data is Always at Risk: No cloud service provider is perfect. And your data will always be at some form of risk on their platform. The backup servers, for example, of a cloud based platform are just as vulnerable to acts of God and hackers. Data loss, therefore, cannot be eliminated and requires additional solutions.

How Do You Avoid these Risks?

Thankfully, all of these risks can be minimized. The key to success is planning in every aspect of the migration. So, make sure that your organization does the following:

  • Configure Slowly and Carefully: Migrating to the cloud is not something that can be rushed. You need to proceed slowly and ensure that everything is set up correctly. And this is most important when it comes to privileges. These need to be managed correctly to minimize the risk of unauthorized access causing major problems for your security.
  • Establish Prior Training: Cloud technology is relatively new and this has resulted in a lack of available skills being available. But this does not have to be a definitive situation for your business. So, the first step of your cloud migration should be to establish a training program. By proceeding in this manner you will ensure a hassle free migration.
  • Work with Multiple Backup Methods: You should never rely on just one form of data storage. And the cloud is no different. To minimize the risk of any data disasters it’s crucial that you work with multiple backup methods. It could be the difference between your data being available and your organization remaining functional.

Hardware can easily become compromised, stolen or damaged. And this can leave you without crucial data. But the 3-2-1 backup method is here to help.

Data disasters are most often caused by hardware failure, human error or cyber-attacks. Regardless of the cause, your organization needs a good backup strategy in place. You need to be able to retrieve your data in the event of an emergency. Without a backup strategy you will struggle to recover and this will have a major impact on your productivity. And that’s why the 3-2-1 backup method has proved to be so popular with businesses.

Data protection has never been more important that today, so we’re going to take a look at how the 3-2-1 backup method can protect your data.

What is the 3-2-1 Backup Method?

The principle behind the 3-2-1 backup method lies in its name:

Let’s take a closer look at each part of the method to help you understand the thinking behind it:

  • Keeping at Least 3 Copies of Your Data: To keep just one backup copy of your data is careless. Say, for example, your data is compromised by ransomware. An option would be to retrieve your backup data from an external hard drive. But what if you discover this device has been damaged in some way? You need an alternative solution. And this could be accessing a USB drive or connecting to a cloud storage solution. The minimum number of copies you should keep is three, but there’s no maximum. You can keep three, five or fifty. 
  • Keeping 2 of these Copies on Local Devices: Onsite backups are essential for keeping your productivity in place. Data disasters are unpredictable and can have an instant impact. Therefore, you need to make sure that you have your backup data close to hand. This approach will allow you to quickly implement any compromised data and establish normal working practices. Again, it’s important to have more than one local backup available to safeguard against any technical issues. 
  • Keeping at Least 1 Copy Offsite: If you want to reap the benefits of a complete backup strategy you need to keep one copy offsite. Advances in cloud computing mean that it’s easier than ever to store data offsite. And this can pay dividends in the case of a local disaster. If, for example, you are hit by a hurricane or a flood, all your local backups could be damaged. It doesn’t matter if you’ve got three or three hundred. But if you keep at least one copy in the cloud you are ensuring comprehensive data protection is in place. 

Final Thoughts 

A good backup strategy is vital in protecting your data in the event of a data disaster. And it pays to be comprehensive in the manner in which you protect your data. The 3-2-1 backup method is the perfect way in which to achieve this.

How Reliable is your Hard Drive?

All hard drives have a limit in terms of space. And this limit can soon be reached. But there are a number of simple ways to free up space.

A hard drive which is full can cause you a number of problems. Speed is the most obvious issue, but the chances of your PC freezing and crashing is also increased. And all of these scenarios are ones that can put a drain on your productivity. Therefore, you need to ensure that you have enough space on your hard drive.

You could expand your storage space, but this can be costly and isn’t always required. Instead, you can restore your PC’s productivity by following our steps to free up space.

Maximizing the Capacity of Your Hard Drive

To start freeing up space on your hard drive you need to make sure you follow these best practices:

  • Disk Cleanup: The simplest way to start maximizing space on your hard drive is with the Disk Cleanup application. This maintenance utility is bundled with Windows and carries out a quick evaluation of your hard drive. Files that are deemed necessary are kept, but there’s also an option to delete unnecessary files. 
  • Uninstall Apps You No Longer Use: A large number of apps will be installed on a PC over the course of its lifetime. But, due to time constraints, these aren’t always uninstalled when they’re no longer required. And this can take up a lot of disk space. So, you need to regularly visit the ‘Uninstall or Change a Program’ section of your Control Panel. Here you can analyze which programs are no longer required and remove them. 
  • Minimize Your System Restore Space: It’s likely that you will have used the System Restore app more than once to fix a system issue. But, over time, all the snapshots of your system can start to take up large amounts of space. Thankfully, you can restrict the amount of space used to store these snapshots. By minimizing the maximum Disk Space Usage you can save space on your hard drive. Just remember that this will also minimize the number of restore points you can access.
