With the world shifting to an increased hybrid working environment in recent times, several businesses have been changing the way they work. This has also meant that more and more workplaces are looking at service virtualization and adapting to Red Hat Enterprise Virtualization as part of this shift. But such virtual working environments can pose a threat to data security or result in cyber-attacks. So, it requires a lot more planning to ensure that all virtual machines and the data they work on are safe and adequately protected.

So, it is important for companies opting for Red Hat Virtualization to follow some data management practices that can make this migration smooth and ensure that all the data is kept safe. Here are some best practices that you must follow:

Invest In Hypervisor-Level Backups

Unlike the traditional methods of taking data backup that involved installing a backup client or agent software, enterprise-class platforms like Red Hat Virtualization offer a series of APIs that perform what is known as hypervisor-level backups. In certain cases, it is also referred to as an agentless backup. This allows backup applications to take backup and perform recovery processes through the hypervisor. This limits the performance impact on the VM allowing better control over the recovery processes.

Take Backup At A Secondary Location As Well

One of the best practices of data security management is storing the data at an alternate location so that it can be recovered or accessed in case the primary backup system failure. Most organizations are known to take the 3-2-1 approach where 3 copies of your data are stored in 2 different types of storage media out of which at least 1 is at a remote location. Increasingly, the Cloud is being utilized to serve as the remote location. Following this data management practice provides the maximum possibility of data recovery.

Incremental Backups

Backing up data on a timely basis is important but can also consume a lot of resources. To avoid this, Changed Block Tracking (CBT) is used by most organizations that only saves data blocks that have been changed since the last backup. This decreases the backup time to a large extent and significantly increases the efficiency of the resources on the hypervisor, the backup server, as well as the entire network infrastructure. Since the Red Hat Virtualization does not have its own CBT API, it will use the one provided by your backup software.

Never Use Snapshots As Your Primary Backup

One of the features of Red Hat Virtualization is that it allows you to take a virtual snapshot of a virtual machine. This snapshot can be used to return your virtual machine to its previous state. But make sure you never use this snapshot as your primary backup. They are not the copy of the virtual machine. In fact, it is just a delta of the information that might have changed in your virtual machine from the time the snapshot was taken. This is what allows your virtual machine to roll back to its previous state. These snapshots are often stored in the same database as the VMs are and over time, they tend to become extremely large in size. So, storing both your snapshots and VMs can pose a challenge in the data storage process.

Create A Safe And Efficient Backup Storage Environment

Data security and protection are core components of the Red Hat Virtualization process. So, it is important to create an efficient data backup system for faster data storage, especially considering the amount of data that a backup system stores and transfers. Deduplication is now a common feature in almost all backup products today that ensures that only unique data is stored and saved so that the servers and systems store less data. Simultaneously, it is also important to ensure that the data is safely and securely encrypted while transferring it across the network and saving it to prevent data breaches.

Make Sure You Test Your Backups

Data backup is done to ensure that all the important information can be recovered in the event of a Disaster. So, testing your data backup system is a crucial step in data security management. This ensures that your backup data is not corrupted. You don’t want to be in a situation where you need to recover the backed-up data only to realize that it has been corrupted.
In a world where more and more organizations are moving towards virtual operations, data security and backup have become primary operations that every company must undertake. And Red Hat Virtualization is a full-proof way of ensuring that your data is not only saved properly but can be recovered when the need arises.
In addition to this, periodic Disaster recovery drills are highly recommended. This ensures the health of the backup data and sets realistic expectations on the RTO (Recovery Time Objective) in an event of a Disaster. Disaster recovery drills and periodic backup restores also helps you check that your backup copies are ransomware free.
