Kubernetes backup and key players



Kubernetes backup and key players

Containers and container orchestration, most often via Kubernetes, are revolutionizing the way companies develop and run their applications.

Containerised architectures allow organisations to develop, deploy and decommission applications quickly. Containerised applications can be easily moved between cloud and on-premise systems. This is a key advantage for some companies.

But enterprises are increasingly using containerised applications to manage more critical data – and these data need to be backed .

One of the arguments in favour of containers has been that no backups are needed, because the architecture is stateless and applications are often designed to have a very short working life (most operate for less than a day). Any stateful components are spun up from the central, key-value store, known as etcd.

This is a great option for web-based applications and rapid application development. Enterprises will need to protect containers as they are used to replace traditional applications. Protecting the etcd database as well as any data stored on persistent volumes is essential.

” Generally speaking, organisations don’t back up Kubernetes using native tools, if at all,” said Brent Ellis, senior analyst at Forrester. “Many product teams back up the etcd configuration database for their clusters, then they back up the primary storage that the container images are stored in and any persistent volumes references in the yaml files.

“This works well if your application is simple and Kubernetes has applications with minimal or zero state. Application awareness is required to backup an application’s state and capture any instances in which data transformations were skipped in the event of a disaster .”

This is leading to two main approaches to Kubernetes backup: dedicated products and broader-based recovery and backup tools that can support container environments. This is not a comprehensive market overview.

Kasten K10

Kasten positions its K10 software as a purpose-built, Kubernetes data management solution. The application runs on its own Kubernetes namespace and supports both cloud and on-premise architectures. The tool scans components for backups, including persistent storage volumes or databases. You can create your own policies for data protection, back-up and disaster recovery (DR).

In 2020, backup vendor Veeam bought


Portworx is a pioneer in persistent storage for containers. It can also provide backup for Kubernetes environments. It does this through its PX-Backup software, which it claims is “container granular and app aware”. It supports file, object and block storage. It includes storage discovery and provisioning tools as well as backup, DR security, and migration features.

Pure Storage bought Portworx in 2020.


Verelo, an open-source backup, restore, recovery, and migration tool for Kubernetes, is Verelo. It can backup entire clusters or individual parts using namespaces or label selectors. This tool can also restore Kubernetes API programming interface (API), groups according to priority level. Velero was previously Heptio Ark.

Although Velero is open source, it is supported by VMWare, and the vendor has a number of Velero resources in its Tanzu developer centre.

Red Hat OpenShift Container Storage

Red Hat – now part of IBM – introduced significant Kubernetes support to its Data Services line in 2020, replacing previous IBM offerings.

Red Hat’s OpenShift Container storage adds the vendor’s data protection tools for container environments without any additional technology or infrastructure. Snapshots can be taken via the container storage interface. Clone existing data volumes are also possible. OpenShift APIs allow you to restore data and apps in container pods. You can also restore connections between persistent data and namespaces.

The toolset also links to IBM’s Spectrum Protect Plus services and to TrilioVault and Kasten K10.

NetApp Astra Data Store

NetApp’s Astra Data Store provides a file service that can be used to store virtual machines (VMs), and containers, using a standard NFS client. Astra’s purpose is to simplify storage between containers and VMs, and make it more efficient. It allows firms to use the exact same storage pool and backup tools across both architectures.

NetApp upgraded its Astra Control software to support other Kubernetes platforms such as Rancher and community Kubernetes. It makes use of NetApp’s backend technologies to protect data, DR, and migrate.


Rancher provides its own backup and restore operator from v2.5 of its environment upwards. This operator must be installed on the Kubernetes cluster. It backs up Rancher. The Rancher UI supports cluster and etcd backups. These backups can be saved locally, or to an S3 compatible cloud target.


Trilio positions its TrilioVault tool as cloud-native data protection for Kubernetes. Trilio is application-centric and offers a broad range of Kubernetes platforms and cloud support. The core Kubernetes APIs are used, as well as the CSI framework. The management console allows for application discovery, backup and restore, and policy management. It also supports snapshots.

TrilioVault can be certified for a variety of deployments including VMWare Tanzu, Rancher, and HPE.


Cohesity positions its Helios backup tool in the cloud as a container-native service. The vendor supports the three hyperscale platforms and backs up persistent states, persistent volumes, and operational metadata. Multicloud support allows for backups and restores across multiple cloud providers to increase resilience.

Cohesity also offers zero-cost copies so DevOps teams have access to backup data for application development.

Veritas NetBackup

Veritas NetBackup tools offer a variety of backup and recovery options, as well as business continuity options for Kubernetes. Veritas offers ransomware protection via standard backups and immutable backups of AWS S3 as well as Kubernetes data administration with integrated disaster recovery. Veritas claims that its tools enable users to migrate between Kubernetes distributions, allowing for a “backup one, recover from and then to anywhere” approach.


Catalogic’s Cloudcasa is relatively unusual in the market in that it operates as backup-as-a service. It provides cluster-level recovery and free snapshots, retained for 30 days, along with a range of paid-for options including Kubernetes Persistent Volume (PV) backups. Cloudcasa supports Amazon EBS snapshots as well as CSI snapshots.

Kubernetes-native vs general backup: Beware doubling-up

It isn’t always easy to choose the best backup and recovery options. However, some firms might find that they require more than one tool in order to protect their infrastructures.

“DevOps teams are buying many of the Kubernetes-native backup tools directly,” states Ellis at Forrester. A product team can initiate a purchase of TrillioVault and Kasten. The CIO and their teams continue to purchase more comprehensive backup tools. Understanding the importance of Kubernetes native back-up in this part of the organization is slightly behind .”

CIOs must balance the richer functionality of native Kubernetes and the more granular controls provided by native Kubernetes tools, with the enterprise-wide view of apps and data provided in general-purpose, but container-aware backup and recovery tools.

” “In the comprehensive backup tools I think Kubernetes’ native backup is viewed in tables stakes,” Ellis says. Although almost all enterprise-level vendors claim that they can back up Kubernetes , not all do it natively .

Nothing announces official launch date for new Ear (stick) AirPods alternatives




Nothing announces official launch date for new Ear (stick) AirPods alternatives

True to form, Nothing has just announced the full reveal date for its upcoming audio product, Ear (stick). 

So, an announcement about an announcement. You’ve got to hand it to Carl Pei’s marketing department, they never miss a trick.

What we’re saying is that although we still have ‘nothing’ conclusive about the features, pricing or release date for the Ear (stick) except an image of another model holding them (and we’ve seen plenty of those traipsing down the catwalk recently), we do have a date – the day when we’ll be granted official access to this information. 

That day is October 26. Nothing assures us that on this day we’ll be able to find out everything, including pricing and product specifications, during the online Ear (stick) Reveal, at 3PM BST (which is 10AM ET, or 1AM on Wednesday if you’re in Sydney, Australia) on (opens in new tab)

Any further information? A little. Nothing calls the Ear (stick), which is now the product’s official name, “the next generation of Nothing sound technology”, and its “most advanced audio product yet”. 

But that’s not all! Apparently, Ear (stick) are “half in-ear true wireless earbuds that balance supreme comfort with exceptional sound, made not to be felt when in use. They’re feather-light with an ergonomic design that’s moulded to your ears. Delivered in a unique charging case, inspired by classic cosmetic silhouettes, and compactly formed to simply glide into pockets.” 

Opinion: I need more than a lipstick-style case

Nothing Ear (stick) – official leaked renders 1, 2022

It’s no secret that I want Nothing’s earbuds to succeed in world dominated by AirPods; who doesn’t love a plucky, eccentric underdog? 

But in order to become some of the best true wireless earbuds on the market, there is room for improvement over the Nothing Ear 1, the company’s inaugural earbuds. 

Aside from this official ‘news’ from Nothing, leaked images and videos of the Ear (stick) have been springing up all over the internet (thank you, developer Kuba Wojciechowski) and they depict earbuds that look largely unchanged, which is a shame. 

For me, the focus needs to shift from gimmicks such as a cylindrical case with a red section at the end which twists up like a lipstick. Don’t get me wrong, I love a bit of theater, but only if the sound coming from the earbuds themselves is top dog. 

As the natural companions for the Nothing Phone 1, it makes sense for the Ear (stick) to take a place similar to that of Apple’s AirPods 3, where the flagship Ear (1) sit alongside the AirPods Pro 2 as a flagship offering. 

See, that lipstick case shape likely will not support wireless charging. That and the rumored lack of ANC means the Ear (stick) is probably arriving as the more affordable option in Nothing’s ouevre. 

For now, we sit tight until October 26.

YouTube could make 4K videos exclusive to Premium subscribers

You might soon have to buy YouTube Premium to watch 4K YouTube videos, a new user test suggests.

According to a Reddit thread (opens in new tab) highlighted on Twitter by leaker Alvin (opens in new tab), several non-Premium YouTube users have reported seeing 4K resolution (and higher) video options limited to YouTube Premium subscribers on their iOS devices. For these individuals, videos are currently only available to stream in up to 1440p (QHD) resolution.

The apparent experiment only seems to be affecting a handful of YouTube users for now, but it suggests owner Google is toying with the idea of implementing a site-wide paywall for access to high-quality video in the future.

So, after testing up to 12 ads on YouTube for non-Premium users, now some users reported that they also have to get a Premium account just to watch videos in 4K. 1, 2022

It’s no secret that Google has been searching for new ways to monetize its YouTube platform in recent months. In September, the company introduced five unskippable ads for some YouTube users as part of a separate test – an unexpected development that, naturally, didn’t go down well with much of the YouTube community. 

A resolution paywall seems a more palatable approach from Google. While annoying, the change isn’t likely to provoke the same level of ire from non-paying YouTube users as excessive ads, given that many smartphones still max out at QHD resolution anyway. 

Of course, if it encourages those who do care about high-resolution viewing to invest in the platform’s Premium subscription package, it may also be more lucrative for Google. After all, YouTube Premium, which offers ad-free viewing, background playback and the ability to download videos for offline use, currently costs $11.99 / £11.99 / AU$14.99 per month.

Suffice to say, the subscription service hasn’t taken off in quite the way Google would’ve hoped since its launch in 2014. Only around 50 million users are currently signed up to YouTube Premium, while something close to 2 billion people actively use YouTube on a monthly basis. 

Might the addition of 4K video into Premium’s perk package bump up that number? Only time will tell. We’ll be keeping an eye on our own YouTube account to see whether this resolution paywall becomes permanent in the coming months.
