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 .

Microsoft Teams is finally fixing this ear-splitting annoyance




Microsoft Teams is finally fixing this ear-splitting annoyance

One of the most irritating (and slightly painful) parts of joining a Microsoft Teams call could soon be fixed by a new update.

The video conferencing service is a popular choice for many companies, meaning calls with large numbers of participants joining at the same time, and from the same location (such as a meeting room) are a common occurrence. 

However, often when multiple people join a meeting in the same room, a feedback loop is created, which causes echo, which in most cases quickly escalates to howling – with Microsoft likening the noise to when a musician holds the mic too close to a loudspeaker.

Teams’ howling

Fortunately, a new fix is coming for Microsoft Teams users. In its entry in the official Microsoft 365 roadmap (opens in new tab), the new “Ultrasound Howling Detection” describes how it aims to prevent this noise for users on Windows and Mac across the world.

Microsoft says that the update should mean if multiple users on laptops join from the same location, it will share with the user that another Teams Device is detected in their vicinity and is already joined with audio to the current meeting. 

If a user has already joined with their audio on, Microsoft Teams will automatically mute the mic and speakers of any new the person who then joins the call, hopefully putting an end to the howling and screeching feedback.

Thankfully, the update is already listed as being in development, with an expected general availability date of March 2023, so users shouldn’t have to wait too long to enjoy.

The news follows a number of recent updates largely aimed around improving the audio quality on Microsoft Teams calls using AI and machine learning.

The new updates are the result of using a machine learning model trained on 30,000 hours of speech samples, and include echo cancellation, better adjusting audio in poor acoustic environments, and allowing users to speak and hear at the same time without interruptions.

Shazam! Fury of the Gods trailer breakdown: 6 thing you might have missed




Shazam! Fury of the Gods trailer breakdown: 6 thing you might have missed

The final trailer for Shazam! Fury of the Gods has debuted online – and it looks even more charming, funnier, frenetic, and darker than its predecessor.

Shazam’s sequel flick arrives in theaters worldwide on March 17, so it’s about time we were given another look at the forthcoming DC Extended Universe movie (read our DC movies in order guide to find out where it’ll fit in that timeline). Luckily, Warner Bros. has duly obliged. Check it out below:

Okay, there’s some messy CGI and a slightly corny vibe about Shazam 2. But hey, the first problem can be ironed out before the superhero film takes flight, while the latter is part of what makes this movie series spellbinding (see what we did there?).

But we digress – you’re here because you want to find out what you missed from Shazam! Fury of the Gods‘ new trailer. Below, we’ve pointed out six things you might have overlooked. So, what are you waiting for? Shout “Shazam!” and let’s dive in.

1. Who are the Daughters of Atlas?

For a film centered around Shazam, we don’t actually see the titular superhero appear in the official trailer for the first 20 seconds.

Instead, we get another glimpse at Fury of the Gods‘ villains, aka the Daughters of Atlas. The powerful trio comprises the power-hungry Hespera (Helen Millen), dragon-riding Kalypso (Lucy Liu), and Athena (Rachel Zegler), the latter of whom seems particularly torn about how the sisters are going about their business.

So, why are they gunning for Shazam and his superpowered foster siblings? Essentially, when Billy Batson was gifted his abilities by Djimon Hounsou’s wizard in the film film (available now on HBO Max), one of those powers was the Stamina of Atlas. The Daughters of Atlas aren’t too happy about their father’s ability being passed down to a child, so they want to take back what is theirs – and they’ll do it so by any means necessary.

2. Mythological monsters

Shazam’s first DCEU outing featured some horror-imbued creatures in the form of the Seven Deadly Sins. How, then, do you go about topping (or, at the very least) matching what came before? Throw in a bunch of myth-based monsters, of course.

Kalypso’s imposing dragon is the most notable inclusion. It feature prominently throughout the trailer, and we even get an amusing Game of Thrones reference from Shazam – “Hey, Khaleesi!” – in the movie. Hey, Warner Bros. loves to mention its suite of IPs in as many of its films as possible.

But Kalypso’s wyvern isn’t the only fairy-tale-based beast we see. Minotaurs, griffons, and demonic unicorns are just three of the other monsters who’ll turn up in Fury of the Gods. Basically, don’t expect this to be an easy fight for Shazam and company to save the world.

3. You can’t get the staff these days

Saving earth from a new titanic threat will be even harder when Shazam’s adoptive family are stripped of their powers, too. And it seems that the staff, which was wielded by Hounsou’s wizard in the first movie, is the key to giving and taking those abilities away.

In 2019’s Shazam!, the titular hero gave powers to his foster siblings to help him combat the Seven Deadly Sins and Doctor Sivana. They’ve still got those power in Fury of the Gods, too, but they won’t have them for long, based by what the trailer suggests.

The footage shows Freddy Freeman and Mary Bromfield being drained of their abilities by the Daughters of Atlas at various points. The trio are using the wizard’s staff to rob the teens of their powers, so it’s clearly of major importance to the movie’s main players. 

Later, we see Shazam wielding it – not before he asks the wizard to take his powers back, mind you, when he becomes convinced he can’t defeat the Daughters of Atlas. Anyway, Shazam’s brandishing of the staff suggests he needs it to boost his own abilities if he’s going to defeat the movie’s antagonists and give his siblings their powers back. Expect the staff to play a vital role in Fury of the Gods‘ plot, then.

4. Prison break

In order to get the wizard’s staff, it seems the Daughters of Atlas go after Hounsou’s magic wielder to obtain it.

We see Hounsou’s character imprisoned at various points, including a shot of Hespera chastising him for giving the power of the gods to Billy, Freddy, and company. “You ripped it from our father’s core,” she tells him, which implies Hounsou’s wizard might not be as mighty and heroic as we were led to believe.

Anyway, Hounsou’s wizard interacts with Shazam later in the trailer, so he clearly escapes captivity. Whether he does so alone, or he enlists Shazam’s help – does that magic-infused dust, which he sends through his prison cell window, have something to do with it? – is unclear. Regardless, we’ll see Hounsou’s character break out at some stage.

5. Is that you, Doctor Strange?

Where have we seen this kind of aesthetic before? (Image credit: Warner Bros.)

Remember when we said Zegler’s Athena doesn’t seem as keen to destroy earth as her sisters? That’s because, at the 1: 14 mark, we see her use her powers with a uncertain look on her face. You wouldn’t look like that if you were convinced you were doing the right thing, would you? 

Based on the fact she’s pushed away by Kalypso (using the staff no less), seconds later, it seems she’ll be swapping sides at some stage.

Interestingly, it seems the wizard’s staff can do more than give or take a person’s powers away. One perceived ability certainly has an air of the Doctor Strange/Marvel-based mystic arts about them. Just look at the Escher-style nature of how the scenery bends and folds in on itself when Athena is pushed back, and when Shazam evades numerous buildings at the 1: 44 mark. We’d be very surprised if DC and Warner Bros. didn’t take a leaf out of the MCU’s book with such an aesthetic.

6. Light the way

Shazam and his fellow superheroes get a costume upgrade in Fury of the Gods. The group’s threads are more streamlined and less plastic-looking this time around, which is pleasing to see.

Fans had been worried, though, that these suits wouldn’t feature one of the first movie’s most underrated (if somewhat tacky) aspects: the glowing lightning bolt on Shazam’s chest. Shazam’s costume in the 2019 movie was manufactured in a way that allowed the bolt to physically light up, avoiding the problem of having to add awkward lighting effects during the post-production phase.

Thankfully, Shazam! Fury of the Gods‘ official trailer confirms that Shazam’s lightning bolt will glow. However, given the sleeker look of the costumes this time around, it appears that the illumination effect has been added in post. Regardless of how it’s been implemented, we’re just glad it’s a feature that’s been retained.
