# VStor

Fixed-capacity hardware appliances buy immutability in vendor-sized increments. What that costs over a refresh cycle, and what changes when the storage layer is software-defined.

Learn how to connect Proxmox VE to Catalogic DPX 4.16, create an agentless backup job to vStor, and test a full virtual machine restore.

If you're comparing Veeam alternatives, here's where Catalogic DPX lines up with Veeam and where it differs, from agent-based and agentless backup to GuardMode ransomware detection and tape support.

Proxmox Backup Server is a strong fit for Proxmox-only environments. See when multi-hypervisor estates, long retention, immutability, and central reporting call for Catalogic DPX 4.16 instead.

Most enterprises run multiple hypervisors. See how Catalogic DPX protects VMware, Hyper-V, and Proxmox from a single unified backup platform — with ransomware protection built in.

Two questions decide an immutable storage design: which recovery points need to be where, and how the team will prove a restore works. Plus three worked scenarios.

Immutable storage keeps data from being changed or deleted for a set period. How it differs from WORM, how deletion locks actually work, and what it does and does not protect against.

DPX 4.15 delivers NDMP management in the web UI, VMware tag-based backup scoping, KMIP key management in vStor, and client-side cloud archive encryption. Here's what changed and why it matters.

Bare metal recovery (BMR) rebuilds a complete system, including the operating system, applications, settings, and data, onto a machine with nothing installed on it. How it works, when to use it, and how Catalogic DPX handles it.

DPX 4.13 brings in new backup verification and built-in malware scanning, so you can detect problems early and fix them before a restore is ever needed.
