Immutable Storage for Backups Without Appliance Lock-In

Mon, 17 Aug 2026 00:00:00 +0000

Most organisations do not choose appliance lock-in. They arrive at it one purchase at a time, and notice when the third expansion quote lands. If you are holding a refresh quote and wondering whether that capacity increment is really the only option, this is the arithmetic underneath the feeling, and what changes when the storage layer stops being the hardware.

Worth separating two things that get bundled together. An appliance as a form factor is a good idea: pre-sized, software matched to the platform, quick to stand up. vStor ships as a virtual appliance for exactly that reason, and DPX is deliberately multi-function in the purpose-built backup appliance sense.

How to Back Up Proxmox VE with Catalogic DPX 4.16

Mon, 10 Aug 2026 00:00:00 +0000

Setting up a reliable Proxmox backup should include more than getting one successful job. You need to know which virtual machines are protected, where their recovery points are stored, and whether you can restore a working VM when it matters.

This guide walks through that process with Catalogic DPX 4.16. You will add a Proxmox VE cluster to DPX, install the required host plugin, create an agentless backup job to vStor, and test a full virtual machine restore. The instructions reflect the current DPX 4.16 Proxmox documentation as of August 10, 2026.

Looking for a Veeam alternative? What to compare before you decide

Mon, 03 Aug 2026 00:00:00 +0000

If you’re wondering whether there are alternatives to Veeam and how they compare, this guide walks through one of them, Catalogic DPX, and where it lines up with Veeam and where it differs.

If you’d like to see a practical example, take a look at our case studies in resources.

At a glance: Veeam vs. Catalogic DPX

Agent-based and agentless

DPX has been protecting data for over 25 years, and its architecture reflects how infrastructure has evolved over that time. Rather than committing to one backup method, DPX supports both agent-based and agentless backup, so the method can be chosen per workload rather than dictated by the platform.

Beyond Proxmox Backup Server: When Do You Need More?

Mon, 27 Jul 2026 00:00:00 +0000

Companies moving to Proxmox VE usually reach backup planning early in the migration. Proxmox is straightforward to run, and its licensing gives teams more freedom in how they build their infrastructure.

For many environments, Proxmox Backup Server is the right answer. It comes from the same company and plugs straight into Proxmox VE. PBS provides incremental backups, deduplication, encryption, replication, file-level restore from VM and container backups, live restore that starts a VM while its data is copied, and tape support. A Proxmox-only environment with retention measured in weeks or months may have no need for a second product.

Backing up multi-hypervisor environments: challenges, mistakes, and how to get it right

Thu, 09 Jul 2026 00:00:00 +0000

Most IT environments today run more than one hypervisor. A company might have VMware vSphere as its primary platform, Hyper-V running on older Windows Server infrastructure, and one or more additional platforms picked up through growth, acquisitions, shifting infrastructure requirements, or Total Cost of Ownership initiatives. Nutanix AHV, Proxmox VE, OpenStack, and Canonical MicroStack are all common additions to an estate that started somewhere else. The latter is increasingly common, with many organizations actively evaluating or migrating away from VMware as licensing costs and pricing models have changed. That mix of platforms is not unusual. In fact, it is close to the norm for any organization that has evolved organically over the years or gone through mergers and budget cycles.

Planning Immutable Storage: What to Keep Local, What to Replicate, and How to Prove It Works

Mon, 15 Jun 2026 00:00:00 +0000

A protected snapshot nobody can find during an incident is not a recovery capability. If you are designing immutable storage rather than reading about it, two decisions do most of the damage when they go wrong: what belongs where, and whether anyone has proven the restore runs. Both are answerable on paper, before a purchase order exists.

What should stay local, be replicated, or be archived?

Start from recovery intent, because each copy is doing a different job.

What Is Immutable Storage? WORM, Deletion Locks, and What They Actually Protect

Tue, 05 May 2026 00:00:00 +0000

If you are specifying backup storage and the requirement says “immutable”, this is what that word actually buys and where it stops. Immutable storage will not let data be changed or deleted for a defined period, no matter who asks. Its value for backup is narrow and specific: it takes the administrator, and anyone holding stolen administrator credentials, off the list of people who can destroy a recovery point.

Immutability and WORM are not the same thing

The two terms get used interchangeably and they are related, but they come from different places.

DPX 4.15: Modern NDMP Backup Management, VMware Tags, and Enterprise Encryption

Thu, 09 Apr 2026 00:00:00 +0000

DPX 4.15 is shipping with four areas of meaningful change: full NDMP management in the web interface, VMware backup scoping by vCenter tags, KMIP-compliant key management in vStor, and cloud archive encryption. None of these are speculative features. They deliver on capabilities that our customers have been asking for, and each one has a clear operational payoff.

This post walks through what each feature does, why it matters operationally, and where it fits in the broader context of how organizations manage NAS, VMware, and encryption today.

Bare Metal Recovery (BMR): What It Is and How It Works

Tue, 07 Oct 2025 00:00:00 +0000

Bare metal recovery (BMR) is the process of restoring a complete computer system onto a machine that has no operating system installed. One BMR restore brings back the operating system, applications, configuration, and data together from a single system-level backup image, so nobody has to install Windows or Linux first and then layer the data back on afterwards.

What is bare metal recovery (BMR)?

The name describes the state of the target. Bare metal is hardware with nothing on it, no operating system, no drivers, no middleware. A wiped server counts. So does a freshly created virtual machine, which is why BMR is just as relevant to virtualized estates as it is to physical ones.

New DPX 4.13 Backup Verification Introduction

Wed, 18 Jun 2025 00:00:00 +0000

If your job involves keeping data safe – whether you’re part of an IT operations team, managing infrastructure, or responsible for security- backups are your safety net. They’re what you count on when systems fail, files go missing, or ransomware strikes. The catch is – you have to do backup verification – just because a backup says it completed successfully doesn’t mean it’s actually usable. Many backup systems don’t check if the data they save can be restored. They don’t tell you if the files are corrupt, incomplete, or worse – already infected with malware. So when it’s time to recover, you’re left guessing.

Catalogic vStor A Modern Software-Defined Backup Storage Platform

Tue, 06 May 2025 00:00:00 +0000

Here at Catalogic we can’t stress enough that having solid backups isn’t just important -it’s essential. But what happens when the backups themselves become targets? We’ve built a modern storage solution to address exactly that concern. That means that DPX customers are in a particularly fortunate position. Rather than having to shop around for a compatible backup storage solution, they get vStor included right in the DPX suite. This means they automatically benefit from enterprise-grade features like data deduplication, compression, and most importantly, robust immutability controls that can lock backups against unauthorized changes.

The Power of Granular Recovery Technology: Data Protection and Recovery

Wed, 18 Sep 2024 00:00:00 +0000

Pulling a single file out of a large backup used to mean restoring far more than the file. Traditional recovery works at the level of whole datasets or whole systems, so retrieving one deleted document could involve staging an entire volume somewhere and digging through it.

Granular recovery technology narrows that down. It restores the specific item you lost, whether that is one email, one document, or one database record, and leaves everything else alone.

WORM vs. Immutability: Essential Insights into Data Protection Differences

Sat, 07 Sep 2024 00:00:00 +0000

WORM (Write Once, Read Many) and immutability get used as synonyms, and they are not. Both stop data being changed after it is written, but one is a property of storage and the other is an outcome you design for, and the difference decides what you can actually buy. Here is what separates them, and how Catalogic vStor uses both.

What Is WORM?

WORM is storage that accepts a write once and refuses every later attempt to change or remove it, for as long as its retention term runs. Finance, healthcare and legal all have rules requiring records to survive unedited for a defined period, which is where it earns its keep.

Purpose-Built Backup Appliance: What a PBBA Is and When One Makes Sense

Wed, 04 Sep 2024 00:00:00 +0000

A purpose-built backup appliance (PBBA) is backup software and storage hardware sold as one pre-configured box. You rack it, point workloads at it, and skip the integration work. If you are weighing one against assembling the same capability yourself, the trade is straightforward: you buy speed of deployment and pay for it in flexibility later.

This is mostly a question for teams without spare engineering time, which is why PBBAs sell well into small and mid-sized IT departments.

Boosting Data Security with Cost-Effective Backup Solutions: A Comprehensive Guide

Mon, 02 Sep 2024 00:00:00 +0000

Let’s face it: data security is more important than ever, and the pressure to keep everything safe and sound is only growing. But let’s also be real—budget constraints are a reality for most businesses, and not everyone has the luxury of throwing money at the latest and greatest hardware. That’s why finding a backup solution that’s both cost-effective and robust is key.

Why Cost-Effective Backup Immutability Matters?

One of the big buzzwords in data protection these days is immutability. It’s a game-changer because it ensures that it can’t be altered or deleted once your data is backed up. Imagine you’ve got a vault, and once you close the door, nothing and no one can mess with what’s inside. This is huge when it comes to dealing with ransomware. Attackers often target backups, thinking they’ve got you cornered. But with immutable backups, you’ve got the upper hand—you can restore your data without worry.

Streamlining IT Operations with Comprehensive Backup Solutions: The ‘Batteries-Included’ Approach

Fri, 30 Aug 2024 00:00:00 +0000

When you’re in charge of keeping your company’s data safe, the last thing you want is a confusing maze of backup software, add-on modules, and convoluted licensing agreements. Unfortunately, that’s the reality many IT teams face. Initially, most backup solutions seem like an affordable and comprehensive backup solution, only to discover that essential features like cloud integration or ransomware protection are hidden behind costly upgrades. This piecemeal approach often leads to inefficiency, unexpected costs, and a lot of operational headaches.

Unlocking the Power of Immutability: A Guide to Flexible and Secure Data Backup

Wed, 19 Jun 2024 00:00:00 +0000

In today’s digital-first environment, securing organizational data isn’t just important—it’s crucial for survival. Whether facing natural disasters, system failures, or cyber threats, ensuring that your data remains safe and recoverable is essential. That’s where immutability in solutions like Catalogic DPX vStor becomes invaluable, protecting customer data for over 25 years.

Partner Perspectives on vStor

But don’t just take my word for it. Industry experts and partners who’ve been in the trenches acknowledge vStor’s reliability and simplicity. Chris Matthew Orbit, for example, praises vStor for its robust features and straightforward approach, making it a trusted ally in data protection.
