Benefits of Automation and Orchestration in Backup and Recovery Processes

Five Advancements in Automation Tools and Orchestration Platforms

When the Broadcom company announced its acquisition of VMware on the 26th of May 2022, the virtualization industry was brazing for another great evolution. And this time, we might witness a greater blast in the evolution of virtualization infrastructures. So, at the back of this announcement and the introduction of many virtualization-enhancing features, are we getting into the fourth-age evolution of virtualization infrastructures?

The inception of data virtualization infrastructures focused on relieving the huge task accompanying big data issues of physical machines by granting end-users the opportunity to access and modify data stored across various systems through a single view. Using the ESX hypervisor machine, VMware gained huge momentum in the data management sector. However, while this infrastructure was widely accepted, it contains a series of challenges that made users desire significant improvement.

At the back of this development, the second age of virtualization infrastructures comes into play. This time, a cloud-based data virtualization infrastructure was announced, taking virtualization to a new level where users can access data on popular platforms like Azure, Amazon web, and more. Again, this transition gave users timely access to the database with minimum stress. Then, big companies and the public sector with a data center utilized OpenStack for data positioning. Thus, increasing their accessibility to end users.

The Third virtualization infrastructure age introduced the use of containers in database management on Kubernetes. This transformation aims to allow developers to present their database in independent containerized microservices. Thus, they can promote their services to test, stage, and promotion environments and become readily available to users.

Utilizing ETCD, Kubernetes stores the containerized services, which are only accessible with the help of an API. This development was a big upgrade on the seemingly cumbersome traditional VMs and Hypervisors as it provides users with the needed database at the minimum interval. While data virtualization keeps enjoying a series of upgrades, we might as well say that we are already witnessing the fourth age of evolution. This development makes users curious about what the fourth evolution has in stock and about what the future holds for data virtualization.

So, before moving on to the future of virtualization infrastructures, let’s look at what the buzzing fourth-age evolution is all about and why this development is all for the customer’s good.

The fourth age virtualization infrastructures

Like every other evolution mentioned earlier, the fourth age virtualization comes with another view on virtualization. It is also called the age of evolution and convergence on cloud-native platforms. It aimed at running virtual machines alongside Kubernetes through the help of KubeVirt. The KubeVert project allows KVM-enabled machines to be managed as pods on Kubernetes.

Despite the fame of Kubernetes in recent years, it’s surprising that many projects are still run on virtual machines. With the prolonged coexistence between these two virtualization tools, the new evolution is about having both works as a single system without a requirement for the actual application.

This innovation combines the features of both Virtual machines and Kubernetes to provide a good user experience. In addition to this benefit, KubeVirt grants Virtual machines the opportunity to utilize Kubernetes abilities, as seen with projects like Tetkton, Knative, and the like. These projects work as both Virtual machines and container-based applications.

Features of the fourth age evolution Virtualization Infrastructures

Combining virtual machines and containers into a single system, the fourth-age virtualization tools possess several amazing features that provide a great user experience. Here are the features:

• Virtualization Monitoring
• Pipelines Incorporations
• Utilization of GitOps
• Serverless Architecture
• Service Mesh

Virtualization Monitoring

This is an automated and manual technique that ensures appropriate analysis and monitoring of virtual machines and other virtualization infrastructures. The virtualization monitoring technique has three main processes that enhance its efficacy. This process includes monitoring, troubleshooting, and reporting. This feature guides against untoward occurrences, performance-related issues, unexplainable or architectural changes, and risks.

Also, it allows you to plan capacity better and manage resources adequately. Another benefit associated with virtualization monitoring is the absence of server overload, which makes data processing faster and better. Lastly, virtualization monitoring improves the general performance of virtualization infrastructures by quickly detecting impending issues. With total control of virtualization monitoring processes, a feature seen in previous ages, virtualization monitoring is a key feature in the new infrastructures with more efficiency.

Pipelines Incorporations

Pipelines are aggregates of tasks assembled in a defined order of execution through the help of pipeline definitions. With this feature, a continuous flow integration and delivery of your applications’ CI/CD workflow become organized.

OpenShift Pipeline, based on Kubernetes resources, is an example of how this feature works. In addition, it utilizes Teckton for optimum accuracy. With CI/CD pipeline automation, you can easily escape human errors and maintain a consistent process for releasing software.

Utilization of GitOps

GitOps aims at automated processing, ensuring secure collaboration among teams across repositories. This feature utilizes Git for applications and infrastructure management. GitOps allows for maximum productivity through its ability to offer continuous deployment and delivery. Also, it allows you to create a standardized workflow using a single set of tools.

Furthermore, GitOps provides more reliability through the revert and fork feature. There’s also the provision of additional visibility and fewer attacks on your server. GitOps provides easier compliance and auditing due to the ability of Git to track and log changes. Git also affords users an augmented developer experience while managing Kubernetes updates, even as a newbie to the Kubernetes services.

Serverless Architecture

Serverless computing is an as-used backend service provision method that ensures users face less stress while computing databases. In addition, it allows users to work on a budgeted amount as the user only pays for what they consume. Also, the scalability of this feature makes it possible to process many requests in less time. You can easily update, fix or add a new feature to an application with minimal effort. Moreover, the serverless architecture significantly reduces liabilities as there’s no backend infrastructure to account for.

Lastly, with serverless architecture, efficiency is hundred percent because there’s no idle capacity, as it is usually evoked only on request.

Service Mesh

A feature that uses a sidecar to control service-to-service communication over a network. Service mesh allows different parts of an application to work hand in hand. This feature is commonly seen in microservices, cloud-based applications, and containers. With the service mesh feature, you can effectively separate and manage service-to-service communication in your application. Also, detecting communication errors becomes easier because each exists on an individual infrastructure layer.

Furthermore, the service mesh offers security features such as authorization, encryption, and authentication. As a result, application development, testing, and deployment also become faster. Lastly, having a sidecar beside a cluster of containers is good for managing network services. With this and other amazing features of the fourth-age evolution virtualization, you can incorporate your VMs and containers into a cloud-native platform.

How can you incorporate cloud-native platforms into your business?

While you might be wondering how to get started with a cloud-native platform, the simplest thing to do is research the essence of using Kubernetes and containers and how you can incorporate them into your business. Furthermore, you can also look into organizations running a similar business as you and how they use the cloud-native platform. Then, after understanding how this platform works and how you can transition into the platforms, proceed to download the Red Hat OpenShift.

Install the application, and after the installation, you can download the OpenShift Migration Toolkit for Virtualization. This Toolkit is a guide for efficiently transitioning into the OpenShift Virtualization from the current virtual machines. With this development, you can incorporate your virtual machines into the current Kubernetes. Also, virtual machines will be able to offer OpenShift capabilities such as cluster management, cloud storage, cloud-native platform services, and other amazing features.

Just as the transition from the big old data to the growing virtualization era, virtual machines are fast becoming a thing of the past and should be replaced by more efficient cloud-native platforms. Moreover, with the growing demand for data sharing in the digital world, sticking with an old-time virtualization system might impact your business negatively. Therefore, you need to embrace this latest trend for maximum output.

What does the future hold for virtualization infrastructures?

Looking at how far virtualization infrastructures have changed over the years, it’s safe to say that more exciting features await the evolution of virtualization infrastructures. The digital world keeps expanding with jaw-dropping developments in all sectors. Moreover, cryptocurrency has come to challenge the legal notes for making digital transactions, with robots gradually replacing human efforts, among other innovations.

So, the wave in the evolution of virtualization infrastructures is expected to become stronger over the years. Soon enough, we might expect the innovation of the fifth-age virtualization infrastructures.

Storware Backup and Recovery offers a comprehensive solution for protecting your OpenStack environment.

Here’s a step-by-step guide to get you started with backups and recovery:

Prerequisites:

• OpenStack environment using KVM hypervisor and VMs with QCOW2 or RAW files.
• Storware Backup and Recovery software.

Deployment:

1. Install Storware Backup and Recovery Node: The Storware node can be installed on a separate machine. Ensure it has access to OpenStack APIs and hypervisor SSH.
2. OpenStack API Integration: Configure Storware to communicate with OpenStack APIs like Nova and Glance for metadata collection and VM restore processes.

Backup Configuration:

1. OpenStack UI Plugin (Optional): Install the Storware OpenStack UI plugin to manage backups directly from the OpenStack dashboard. This simplifies backup creation, scheduling, and restores.

2. Backup Schedules: Define backup schedules for your VMs. Storware supports both full and incremental backups.

3. Backup Options:

• Libvirt strategy
• Disk attachment strategy
• Ceph RBD storage backend

All three strategies support full and incremental backups.

Libvirt strategy works with KVM hypervisors and VMs using QCOW2 or RAW files. It directly accesses the hypervisor over SSH to take crash-consistent snapshots. Optionally, application consistency can be achieved through pre/post snapshot command execution. Data is then exported over SSH.

Disk attachment strategy is used for OpenStack environments that use Cinder with changed block tracking. It uses a proxy VM to attach disks to the OpenStack instances. Snapshots are captured using the Cinder API. Incremental backups are supported. Data is read from the attached disks on the proxy VM.

Ceph RBD storage backend

Storware Backup & Recovery also supports deployments with Ceph RBD as a storage backend. Storware Backup & Recovery communicates directly with Ceph monitors using RBD export/RBD-NBD when used with the Libvirt strategy or – when used with the Disk-attachment method – only during incremental backups (snapshot difference).

Libvirt strategy

Disk attachment strategy

Retention Policies: Set retention policies to manage how long backups are stored.

Backup Process:

1. Storware interacts with OpenStack APIs to gather VM metadata.
2. Crash-consistent snapshots are taken directly on the hypervisor using tools like virsh or RBD snapshots.
3. (Optional) Pre-snapshot scripts run for application consistency.
4. VM data is exported using the chosen method (SSH or RBD).
5. Metadata is exported from OpenStack APIs.
6. Incremental backups leverage the previous snapshot for faster backups.

Recovery Process:

1. Select the desired VM backup from the Storware interface.
2. Choose the recovery point (specific backup version).
3. Storware recreates VM files and volumes based on the backup data.
4. The VM is defined on the hypervisor.
5. Disks are attached (either directly or using Cinder).
6. (Optional) Post-restore scripts can be run for application-specific recovery steps.

Additional Notes:

• Storware supports both full VM restores and individual file/folder recovery.

Will robots take over data management? In recent years, backup and disaster recovery system vendors have introduced several significant innovations. But the best is yet to come. 

Modern data protection solutions, encompassing backup, disaster recovery, replication, and deduplication, are constantly evolving. Manufacturers have moved from a stage of manual configuration to automation. However, this is not the end of the road. There is increasing talk about the era of autonomous backup and even autonomous data management. Is this a near future reality, or just a fantasy?

Opinions on this matter are divided. Skeptics cite the example of autonomous cars. Although prototypes have appeared on the streets of San Francisco, the road to their widespread adoption seems to be a long way off. On the other hand, proponents point to robotic vacuum cleaners that are displacing traditional vacuum cleaners from homes. If humans can be eliminated from processes that require high precision, why not do the same in areas closely related to IT?

Automation and autonomy are very similar concepts, sometimes incorrectly used interchangeably. Nevertheless, there are some subtle differences between them. Automation means that the tasks performed are based on pre-defined parameters that must be updated as the situation changes. This is how elevators, office software, washing machines, robotic assembly lines, and most backup and DR systems work.

On the other hand, autonomous processes differ from automated ones in that they are constantly learning and adapting to the environment. In such cases, human intervention is not needed or is minimal. A great example is the aforementioned robotic vacuum cleaners or driverless cars.

The authors of the concept of autonomous data management assume that processes should take place invisibly, although under human control. Autonomy somehow combines automation with artificial intelligence (AI) and machine learning (ML), so that the data protection system intuitively adapts to the situation.

AI and ML technologies enable the automation of data management processes and minimize human intervention and supervision. Proponents of such a solution argue that it increases operational efficiency, extends uptime, improves security, and the level of services offered.

Clouds Force Change

If companies only stored data in on-premises environments, it would be possible to do without autonomous tools, but in the last two years, things have become much more complicated. Enterprises have moved some of their assets to the public cloud, which has contributed to the growing importance of hybrid and multi-cloud environments. It was supposed to be easier and cheaper, but the ongoing adoption of cloud services is causing sleepless nights for many IT managers.

The main problem lies in the excessive dispersion of data, which is located both in the local data center and in external service providers such as Amazon, Google, Microsoft, or smaller local providers. Managing, and especially protecting, digital assets scattered across various locations is a challenge. The situation is worsened by the relatively narrow range of vendors’ tools optimized for managing corporate data for hybrid and multi-cloud environments.

Part of the products provide support for multiple clouds through centralized control, although they consume many expensive resources. There are also efficient solutions, but only within a single cloud environment. Their main drawback is scalability in the clouds of different providers. In any case, in both of the aforementioned cases, operating costs are higher than desired.

Another problem is the excessive haste in implementing cloud technologies, leading to an increase in the number of point solutions. Cloud environment architects, application developers, and analysts implement independent data management solutions, which deepens the chaos and limits the possibilities of central management.

The data protection strategy in the cloud environment also leaves much to be desired. Security specialists emphasize that in today’s world, the most effective way to stop attackers is through preventive measures. Unfortunately, most modern technologies take a passive approach to resources stored in the cloud. In practice, this means that they create backups and restore backups after an attack, which results in unplanned downtime.

In summary, autonomous backup supports operations in multiple clouds, eliminates functional silos, automates all processes with minimal human intervention, and increases cyber resilience through active methods of detecting and preventing ransomware attacks.

To Limit the Role of the Weakest Link

It has long been known that people are the weakest link in the data protection system. This is particularly evident in environments that require fast and data-driven decision-making. It is also undeniable that people are prone to errors and slower than AI-based solutions, especially when it comes to mundane, repetitive tasks.

So will robots send IT department employees to the pasture in the near future? So far, no one is talking about it loudly. According to the authors of the concept of autonomous data management, the best solution in a complex, hybrid and multi-cloud environment is autonomous work. This means that data will self-optimize and repair itself, as well as move between different environments. Self-optimization uses artificial intelligence and machine learning to adapt to the principles and services related to data protection and management. Self-healing is the ability to predict, identify, and correct service errors or performance issues.

On the other hand, self-service assigns appropriate protection policies and manages and deploys applications and services without human intervention. What does this mean?

In the traditional model, a programmer deploying a new application relies on manual processes, which lengthens it. Autonomous data management eliminates all manual tasks, while protecting the application throughout the process, without the need for additional actions on the part of the application developer or IT staff.

Autonomous Data Management – Is It Worth It?

The concept of autonomous data management looks very promising. Importantly, some backup and DR system vendors are announcing the launch of such solutions in the near future, not in the coming years. On the market, you can already find products that use Machine Learning to early detect anomalies that signal an attempt to attack the backup system. Some companies also use partially AI-based solutions combined with DLP systems, which helps classify and tag information, and thus copy and protect the most important data.

However, only the widespread adoption of systems that provide autonomous data management will allow us to answer the fundamental question – is it worth the effort?

Some data protection specialists warn against excessive optimism. In their opinion, the biggest obstacle to the adaptation of autonomy in backup and DR processes may be the collection of a sufficiently wide range of data to be able to analyze various scenarios. It is difficult to imagine that vendors of solutions would share such information with each other.

It is also difficult to count on the openness of IT department employees, as they may fear that new products will deprive them of their jobs. It can also be safely assumed that the term “autonomy” will be overused by marketers, which on the one hand encourages customer investment, and on the other hand, threatens that low ratings of disappointed users will deter potential customers. It is possible that there will be limitations related to computing power, as well as the costs of such a solution. Nevertheless, it is worth closely following such initiatives, especially as it concerns large companies and institutions storing data in different environments.

Storware develops towards autonomous

While full autonomy might still be a distant goal, Storware’s focus on AI and automation is a significant step in that direction. These features have the potential to significantly improve efficiency, reduce human error, and enhance overall data protection.

In the near future, Storware will implement a number of improvements that will allow for:

• Automation: The Backup Assistant and conversational layer aim to automate routine tasks and provide intelligent responses, reducing human intervention.
• Intelligence: Storebrain’s ability to learn from collective data and provide optimal configurations demonstrates a move towards intelligent decision-making.
• Proactive Protection: The integration of AI into Isolayer for threat prevention showcases a proactive approach to data management, essential for autonomous systems.

However, key to achieving full autonomy would be further development in areas like:

• Self-healing capabilities: The system should be able to identify and resolve issues independently.
• Predictive analytics: Accurate forecasting of system behavior and potential problems.
• Continuous learning: The system should constantly improve its performance based on new data and insights.

Snapshots and backups are both crucial for data protection. However, to maximize their benefits, it’s essential to understand their capabilities.

As data volumes and value continue to grow, data has become an invaluable asset for businesses, governments, consumers, and cyber-criminals alike. Cyber-criminals will stop at nothing to steal information or block legitimate users from accessing it. Fortunately, organizations have various tools and methods to protect their data, including backups and snapshots. While these methods share some similarities, they are often mistakenly seen as interchangeable. This article will delve into the fundamental differences between backups and snapshots and how they can complement each other.

The Indispensability of Backups

Until recently, it was common to say that people were either backing up their data or were planning to do so. However, this saying is no longer accurate. It’s increasingly difficult to find individuals or businesses that don’t perform backups. Backups are typically created on a regular schedule (e.g., nightly or multiple times a day) and can include all files on a server, emails, or databases. By archiving data in backups, users are protected against accidental data loss caused by errors, accidental deletions, or other failures. This is why backups are often referred to as “security copies.”

There are several types of backups. The simplest is a full backup, which creates a complete copy of the data to a destination storage device. Other methods include differential and incremental backups. A differential backup only backs up data that has been added or changed since the last full backup. An incremental backup, on the other hand, uses the previous backup as a reference point rather than the initial full backup.

A full backup is a complete copy of the data. If each backup is 10TB, for example, it will consume an additional 10TB of storage. Creating a backup every hour would consume 100TB of storage in just 10 hours. For this reason, storing multiple versions of backups is not a common practice.

The Role of RPO

A challenge with backups is achieving a suitable Recovery Point Objective (RPO), which defines the maximum amount of data loss that can be tolerated and the maximum acceptable time between a failure and the restoration of a system to normal operation. Businesses have varying requirements—some may be satisfied with a 24-hour RPO, while others strive for an RPO as close to zero as possible. For example, losing even a small amount of data in manufacturing companies can lead to production line downtime, lost product batches, and significant financial losses.

Some businesses determine their RPO based on the cost of storage compared to the cost of data recovery. These calculations help determine the frequency of backups. Another approach is to assess risk levels. In this case, a company evaluates which data can be lost without significantly impacting the quality and continuity of its business.

Backups are not optimal for creating short recovery points. Snapshots are much better suited for this purpose, which is why the two technologies should be used together. Snapshots are the preferred solution when high RPO requirements must be met, such as in 24/7 environments like internet service providers.

Snapshots for Specialized Tasks

A snapshot is a point-in-time capture of stored data. Its main advantage is its creation time, which is typically measured in minutes or even seconds. Snapshots are usually created every 30 or 60 minutes and have minimal impact on production processes. They allow for quick recovery to previous file versions at multiple points in time. For example, if a system is infected with a virus, files, folders, or entire volumes can be restored to a state before the attack.

However, snapshots are often a feature of NAS or SAN storage and are stored on that storage. This means they occupy relatively expensive storage capacity, and if the storage fails, users lose access to recent snapshot copies. While individual snapshots do not consume much space, their combined size can increase, leading to additional processing costs during recovery. Therefore, it’s good practice to limit the number of stored copies. Experts recommend not storing snapshots for longer than the last full backup.

Furthermore, migrating a snapshot from one physical location to another does not allow for environment restoration, which is possible with backups. Since a snapshot is not a complete copy of the data, it should not be considered the sole backup and should be combined with backups. In summary, backups provide the ability to restore data over long RPOs, often quickly and in detail, down to the file level.

Types of Snapshots

While snapshot creation processes vary by vendor, there are several common techniques and integration methods.

• Copy-on-write: This method copies any blocks before they are overwritten with new information.
• Redirect-on-write: Similar to copy-on-write, but it eliminates the need for a double write operation.
• Continuous Data Protection (CDP): CDP snapshots are created in real-time, capturing every change.
• Clone/mirror: This is an identical copy of an entire volume.

Summary

Snapshots and backups have their strengths and weaknesses. Generally, backups are recommended for long-term protection, while snapshots are intended for short-term use and storage. Snapshots are typically useful for restoring the latest version of a server within the same infrastructure.

Both snapshots and file backups can be used together to achieve different levels of data protection, and this is actually the most recommended configuration for backup strategies.

Storware 7.0 – what’s new?

Storware 7.0 high level architecture:

Backup → Recover → Thrive

Data security and recovery are critical when dealing with virtualization tools. In the event of an outage or disaster, businesses must be able to rapidly restore virtual machines (VMs) and critical data. Being a virtualization management tool, oVirt not only shines in virtual environment administration but also provides virtual machine full backup and recovery capability.

This article will explore what oVirt is and how its backup and recovery system works.

What is oVirt?

Red Hat created oVirt, a robust open-source virtualization tool that uses the Kernel-based Virtual Machine (KVM) hypervisor.

With a web-based interface, this platform provides a centralized administration solution allowing consumers to manage compute, storage, and networking resources. oVirt facilitates companies’ design, management, and implementation of virtual machines.

oVirt is suitable for small and large companies since it is flexible and scalable.

oVirt as a Basis for Red Hat Virtualization and Oracle Linux Virtualization Manager

oVirt serves as the upstream open-source project for both Red Hat Virtualization (RHV) and Oracle Linux Virtualization Manager (OLVM). Its key role in these virtualization tools highlights its significance in the broader ecosystem of virtualization solutions. Both RHV and OLVM gets to benefit from the continuous development of oVirt. With the new release, both platforms can seamlessly  integrate these new features rapidly while maintaining stability and performance standards expected by enterprise users.

Red Hat Virtualization (RHV)

Red Hat Virtualisation (RHV) Red Hat Virtualisation, which is based on oVirt, delivers an enterprise-grade virtualization solution with additional Red Hat support services. It uses oVirt’s robust management capabilities and also provides features like enhanced security protocols, advanced monitoring tools, and dedicated support options tailored to enterprise customers. Thus, RHV is a suitable option for organizations seeking a reliable virtualization platform backed by professional support.

Oracle Linux Virtualization Manager (OLVM)

Similarly, OLVM is also based on oVirt technology but is tailored specifically for Oracle environments. It integrates seamlessly with Oracle’s suite of products, offering specialized features that cater to Oracle database workloads and applications. This allows OLVM to provide users with a familiar interface while simultaneously ensuring compatibility with Oracle’s ecosystem.

oVirt Backup and Recovery

Backup and recovery are critical components of any virtualization strategy. In an enterprise setting where data integrity and availability are crucial, robust backup solutions ensure organizations can recover quickly from data disasters and loss incidents. Let’s break down the different methods available in a way that’s easy to understand.

Understanding Backup Modes

When using Storware Backup and Recovery with oVirt 4 or later, you can choose from four different backup modes:

1. Disk Attachment:

   • Think of this as creating a digital copy of your VM. The VM’s metadata and disk files are stored separately.
   • Pros: Simple to understand.
   • Cons: Requires a proxy VM in each cluster, and incremental backups aren’t supported.

2. Disk Image Transfer:

   • This method creates a snapshot of your VM’s disks, including any changes made.
   • Pros: Supports incremental backups, and no proxy VM is needed.
   • Cons: Requires oVirt 4.2 or later.

3. SSH Transfer:

   • Data is transferred directly from the hypervisor using SSH.
   • Pros: Can be efficient, especially for smaller environments.
   • Cons: May require additional network configuration.

4. Change Block Tracking:

   • Only the parts of your disks that have changed are backed up, saving time and storage space.
