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.

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.

The 3-2-1 Rule and Cloud Backup: A Love-Hate Relationship

Mon, 17 Feb 2025 00:00:00 +0000

In today’s digital landscape, safeguarding data is paramount. The 3-2-1 backup strategy has long been a cornerstone of data protection, advocating for three copies of your data, stored on two different media types, with one copy kept offsite. This approach aims to ensure data availability and resilience against various failure scenarios. However, with the advent of cloud storage solutions, organizations are re-evaluating this traditional model, leading to a complex relationship between the 3-2-1 rule and cloud backups.

Navigating Microsoft 365 Updates in 2025: How to Prepare for Major Changes

Wed, 08 Jan 2025 00:00:00 +0000

The Microsoft 365 updates in 2025 signal one of the platform’s most transformative periods yet, with a wave of deprecations and retirements set to redefine how businesses manage their environments. From the phasing out of legacy PowerShell modules to changes in Teams and OneNote, nearly every facet of Microsoft 365 is undergoing significant evolution. These updates will impact sysadmins and IT professionals alike, requiring proactive preparation to ensure smooth transitions and prevent disruptions to workflows.

Monthly vs. Weekly Full Backups: Finding the Right Balance for Your Data

Fri, 08 Nov 2024 00:00:00 +0000

When it comes to data backup, one of the most debated topics is the frequency of full backups. For many users, the choice between weekly and monthly full backups comes down to balancing storage constraints, data restoration speed, and the level of data protection required. While incremental backups help reduce the load on storage, a full backup is essential to ensure a solid recovery point, independent of daily incremental changes.

In this post, we’ll explore the benefits of both weekly and monthly full backups, along with practical tips to help you choose the best backup frequency for your unique data needs.

Building a Reliable Backup Repository: Comparing Storage Types for 5-50TB of Data

Thu, 31 Oct 2024 00:00:00 +0000

When setting up a secondary site for backups, selecting the right storage solution is crucial for both performance and reliability. With around 5-50TB of virtual machine (VM) data and a retention requirement of 30 days plus 12 monthly backups, the choice of backup repository storage type directly impacts efficiency, security, and scalability. Options like XFS, reFS, object storage, and DPX vStor offer different benefits, each suited to specific backup needs.

This article compares popular storage configurations for backup repositories, covering essential considerations like immutability, storage optimization, and scalability to help determine which solution best aligns with your requirements.

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.

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

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.

Microsoft 365 – Why OneDrive Backup is Needed

Fri, 27 Jan 2023 00:00:00 +0000

It is clear that the cloud is replacing physical storage formats due to its collaboration and access features, its cost-effectiveness, and data security and resiliency. As organizations continue to store more and more, cloud storage will continue to increase in popularity. One of the most popular forms of cloud storage used by organizations today is Microsoft OneDrive.

OneDrive is a productivity tool that allows users to synchronize files across different endpoints and share those files with other users in the enterprise. It is one of the several applications that make up the Microsoft 365 suite. The other applications include Exchange, Teams, and SharePoint. OneDrive is designed for users to store and share files, along with other collaboration capabilities that make not only daily jobs easier but also the management of shared files across different team members. The great thing about OneDrive being a cloud storage destination is that it enables employees to access their business files, as well as files shared by other people or teams, from different connected devices. In today’s world of remote working, access flexibility is incredibly useful.

Microsoft 365 – Why SharePoint Backup is Needed

Thu, 19 Jan 2023 00:00:00 +0000

SharePoint has become the go-to solution for organizations to manage extensive volumes of shared data in the cloud. Its robust platform streamlines document sharing among teams, making it an indispensable tool, especially as remote collaboration becomes the standard. However, the essential business data stored in SharePoint exposes a critical vulnerability: the risk of data loss without a reliable SharePoint backup strategy. Microsoft 365‘s native features are not designed to provide comprehensive protection, leaving organizations at risk. Implementing a dedicated SharePoint backup ensures your critical data remains safe and recoverable, safeguarding business continuity

Protect Your Microsoft 365 Data with DPX vPlus

Tue, 20 Sep 2022 00:00:00 +0000

We live in a world where data is the new oil. Not only is data valuable for you to maintain and run your business, but if you do not have a plan for data backup and recovery, we can end up paying a high price for it. According to a study by Touche Ross, 90% of businesses without a disaster recovery plan, will fail after a disaster. Meanwhile, more and more critical organizational data is being created, stored, and shared outside of the data center. Oftentimes, this is close to or over 50% of organizational data. This data lives on laptops, tablets, mobile devices and in cloud services, like Microsoft 365. And yet this data can very easily be lost and lost for good without proper Microsoft 365 backup.
