VMware vSphere is a powerful platform that integrates platform virtualization services and software, along with cloud computing capabilities. It is a leader in the enterprise virtualization industry, and for good reason. Many IT-driven enterprises and businesses are dependent on VMware for hosting their critical workloads. VMware vSphere offers many incredible services, and it is important for business leaders and companies to protect their virtual data.
Being struck by malware is now a growing possibility, regardless of your organization‘s size. This is primarily because malicious activities increase with the reliance on virtualization. Therefore, cyber security is an essential consideration for businesses, especially those that cannot afford their data to be compromised. One of the best ways to avoid data loss as a result of malware is backups.
The Importance of Backups
Backing up is a preventative measure you take so that you are ready for when disaster strikes in your VMware vSphere environment. Before you get into VMware backup best practices, it is important to know about the different types of backups.
Backups are the main tool for preventing data loss in the face of component failure. If fault tolerance fails, disaster recovery will be your last option. Disaster recovery is a process that allows you to rebuild an organization’s data after a disaster has taken place. Recovery often pertains to backups, and there are three main types of backups: full backup, incremental and differential backups.
Major Features and Considerations
The best features for VMware backup are ones that focus more on VM-level, incremental and agentless backups. Always keep in mind that there are no binary options that you need to add into your hypervisor. You also need to be aware of the limitations of snapshot management. Make sure never to treat snapshots as a backup. Snapshots should not replace your existing backup policies, and you should only use them as add-ons.
Snapshots are not Backups
If you think snapshots will fulfill all of your data for protection purposes, consider this. Snapshots, replicas, and backups are three different entities, each serving a different purpose. If you rely on snapshots, then you may want to take a second look at your whole data recovery strategy.
This is not to say that snapshots do not have a place in data protection. Data protection differs depending on the nature of the business, so it is possible that snapshots are all that you need. For most companies, though, this is insufficient.
Most of the time, corporations will use all three data protection tools. Snapshots are point-in-time copies, which means they represent the state of the data at the point when the snapshot was taken. In some systems, changes are tracked in real time and snapshots are taken each time you make a change in VMware vSphere.
SQL Log Truncation
In transactional applications such as Microsoft SQL Server, the transaction logs accumulate during the operation of the server. This accumulation leads to a decrease in disk space, and you may end up having no space in the transaction logs. All VM backups have SQL server log file backup. After the backup takes place, you should clean up the log files.
You can also configure your database not to accumulate transaction logs. However, this is usually not the case most of the time. The workflow includes starting the backup, backing up the VM, removing the Log files that are already backed up, and finishing the backup.
Moreover, you can also get your transaction logs backed up on every backup. The server also automatically rids all unused files from the server.

Changed Block Training
One of the interesting things about VMware data protection is that it uses VMware‘s change block tracking. This allows you to have much faster backup times. Not only that, many people fail to realize that it also makes use of change block tracking. This helps facilitate speedier recovery times.
If you are in a situation where you have patched a Windows virtual machine server within your environment, and upon reboot, it starts blue-screening, then the classic approach to solving this is image-level backup. This involves making a complete recovery of the virtual machine.
If the virtual machine is not too big in terms of storage space, then restoring may not take too long. However, if this instance affects about ten percent of the virtual machines, or a sizable part of the environment, then backing up VMware will take an extended time to complete.
Using CBT or changed block training for the recovery process allows the VDP appliance to communicate with the vSphere and work out exactly what blocks have changed since the last successful backup and only recover those specific blocks.
Have Good Site Recovery
Malware attacks, human errors, or other cyber threats can compromise VMware data. Most of the companies that suffer from a data breach are unable to recover due to a lack of preparedness.
Having a strategy in place that works on recovery can be essential if there is data loss. It can save you from downtime costs and also retain your customers. This is why you should have a robust and reliable recovery plan in place so that you can backup VMware virtual machine data.
Final Thoughts
There are many answers to the question, how to backup VMware virtual machine? and each consists of a different strategy, tool, method, and practice. Your best odds when trying to backup virtual machine data is to adhere to VMware backup best practices. Implementing collective strategies will increase your chances of recovery. These strategies may include application-aware backups, image-level backups, snapshots, encrypted backups, and more. Â
