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.

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

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.

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.
