Immutable Storage That Ransomware Cannot Touch
SPIR write-once-read-many (WORM) storage locks your backups the moment they are written — no one can alter, encrypt, or delete them, even with full admin credentials.
Why Immutable Storage Matters
The Last Line of Defense
When ransomware compromises your environment, immutable storage is the one place your data is guaranteed to survive — untouched and recoverable.
Compliance Mandate
GDPR, HIPAA, and financial regulations increasingly require tamper-evident, immutable records with enforced retention policies.
Insider Threat Protection
Immutable storage protects against malicious or compromised administrators who could otherwise delete or alter backups.
The Problem with Conventional Storage
Standard storage cannot guarantee data survives an attack:
- Any admin can modify or delete files on standard NAS and disk storage
- Ransomware encrypts connected storage along with production data
- Retention policies can be bypassed or overridden by privileged users
- No cryptographic proof that backups have not been tampered with
- Replicas and snapshots on mutable storage offer no real immutability
The Spictera Answer
Spictera SPIR delivers true WORM (write-once-read-many) immutability. Once data is written, it is locked for the configured retention period — no user, no process, and no ransomware can modify or delete it. Cryptographic hashes prove integrity. Retention locks enforce compliance automatically, so you never rely on policy alone.
See How It WorksHow SPIR Immutable Storage Works
Hardware-enforced immutability with policy-driven retention.
Write Once
Backups are written to SPIR WORM storage in a single, atomic operation.
Lock Immediately
Data is instantly immutable — no modification or deletion is possible.
Enforce Retention
Retention locks hold data for the configured compliance period, automatically.
Verify Integrity
Cryptographic hashes prove backups have not been tampered with.
Key Features
Enterprise-grade capabilities purpose-built for your environment.
True WORM Immutability
Once written, data cannot be modified or deleted by anyone until the retention period expires — enforced at the storage layer, not by policy.
Ransomware-Proof
Ransomware that gains admin credentials still cannot encrypt or delete your immutable backups.
Compliance Retention Locks
Configurable retention periods enforce GDPR, HIPAA, and financial regulations automatically — no manual override.
Instant Snapshot Recovery
Recover directly from immutable snapshots in minutes, with no restore-from-dump delay.
Point-in-Time Rollback
Restore to any immutable snapshot to undo corruption, deletion, or ransomware.
Unified with SPFS
SPIR works seamlessly with SPFS unified storage for policy-driven tiering and replication.

Frequently Asked Questions
What is immutable storage?
Immutable storage is storage where data, once written, cannot be modified or deleted until a defined retention period expires. It is typically implemented as WORM (write-once-read-many) storage. Immutability guarantees that backups survive ransomware, insider threats, and tampering.
How is immutable storage different from regular backup storage?
Regular storage allows any authorized user to modify or delete files — which means ransomware or a compromised admin can destroy your backups. Immutable storage enforces write-once protection at the storage layer, so no one can alter or delete data regardless of their credentials.
Does immutable storage help with GDPR and compliance?
Yes. GDPR, HIPAA, SOX, and financial regulations require demonstrable, tamper-evident records with enforced retention. SPIR immutable storage with retention locks satisfies these requirements automatically and provides audit trails proving data integrity.
Can ransomware delete immutable backups?
No. Ransomware cannot modify, encrypt, or delete data on SPIR immutable WORM storage — even if it obtains administrator credentials. The immutability is enforced at the storage layer, not by access policy.
What is WORM storage?
WORM (Write-Once-Read-Many) storage allows data to be written exactly once and read many times, but never modified or deleted during the retention period. It is the technical foundation of immutable storage and is required by many compliance regulations.
How fast can I recover from immutable storage?
Recovery from SPIR immutable snapshots is near-instant — typically minutes — because you restore from a snapshot rather than reconstructing data from a slow logical dump. This minimizes downtime after ransomware or data loss.
