Cold Storage product reversibility policy

Objective

This document outlines the reversibility policy for the product Cold Storage covering OVHcloud's Cold Archive offer.

This policy aims at implementing the global reversibility principles and requirements of SWIPO IaaS Code of Conduct for Cloud Providers.

Features map

The product features are divided into three categories:

The core features for which we guarantee the ability to migrate.
The OVHcloud implementation, which migration will require adaptations to a new environment.
Specific functionalities whose migration cannot be guaranteed, as they are tied to the OVHcloud environment or involve specific developments.

Core features

Feature	Description	Available formats	Migration model	Available documentation
Standard S3¹ API Compatibility	Access and management via S3-compatible API (RESTful, AWS CLI tools, SDK, etc.).	S3 (REST, JSON, objects)	Incoming: Direct upload into an Object Storage bucket via S3 API, CLI, or SDK. Outgoing: Direct retrieval/export via S3 API, CLI, or SDK to any other S3-compatible provider.	Cold Archive offer presentation Cold Archive offer documentation
Massive Import/Export of objects	Batch data migration using S3 commands (`aws s3 cp/sync`, etc.).	S3 (objects, folders)	Incoming: Copy data from another S3 solution to OVHcloud Object Storage bucket. Outgoing: Massive export via same tools to another S3 or compatible platform.	Cold Archive offer documentation
Server-Side Encryption	Native AES-256 bucket-level encryption, compatible with S3 SSE.	S3 (SSE-S3, SSE-C)	Incoming: Upload of encrypted or unencrypted data, transparently handled. Outgoing: Export without adaptation; encryption maintained or reprocessed by the target.	Cold Archive offer documentation
Long-Term data Retention	Data stored on magnetic tapes, with a lifespan over 10 years.	S3 (objects)	Incoming: Import without adaptation. Outgoing: Export of objects via S3 API; retrieval on any compatible storage.	Cold Archive offer documentation

OVHcloud implementation

Feature	Description	Available formats	Migration model	Available documentation
Full Bucket Archiving	Archiving applies to the entire bucket (no object-level archiving).	S3 (bucket)	Incoming: Requires grouping of objects to archive into a dedicated bucket. Outgoing: Export objects from the bucket, then import into the target (adaptation may be required if the target does not support bucket-level archiving).	Cold Archive offer documentation
Delayed Restore ("unfreeze")	Data must be "unfrozen" before download (several hours of latency).	S3 (objects)	Incoming: Not applicable. Outgoing: User must initiate a restore ("unfreeze") request, then download the objects within a 24-hour window; adaptation needed if the target lacks this mechanism.	Cold Archive offer documentation
Data Immutability	Ability to make data immutable for a defined or indefinite period (WORM).	S3 (Object Lock)	Incoming: Source must support S3 data immutability. Outgoing: Export possible, but target must support S3 locking or require manual adjustment of immutability policies.	Cold Archive offer documentation

Specific functionalities

Feature	Description	Available formats	Migration model	Available documentation
Anti-DDoS	The anti-DDoS is a set of equipment and means put in place to absorb distributed denial of service attacks. It includes an analysis of traffic, the "aspiration" towards a specialized network, and mitigation, ensured by VAC technology developed by OVHcloud.	N/A	Incoming: The Anti-DDoS is a component of our infrastructure, enabled by default. No action is required. Outgoing: Order and configure an anti-DDoS with the new provider.	OVHcloud anti-DDoS protection Anti-DDoS Technology
OVHcloud 4-Datacenter Architecture	Distribution across 4 datacenters in France using 8+4 erasure coding.	N/A	Incoming: Not applicable. Outgoing: Not transferable, depends on the target architecture.	Cold Archive offer presentation
Management via OVHcloud Manager/API	Proprietary OVHcloud graphical interface and APIs for archive management.	N/A	Incoming: Not applicable. Outgoing: Scripts/APIs need to be rewritten for the target; manual management may be required.	Cold Archive offer documentation

Architecture listing

OVHcloud's Cold Storage product is based on a geo-distributed architecture across four physically separated data centers (several kilometers apart), using IBM magnetic tape technology. Data is stored using 8+4 erasure coding, ensuring extreme resilience and tolerance to the loss of an entire site.

Partner services

OVHcloud partners are listed under the keyword "Cloud Migration" in the dedicated partner directory.

OVHcloud also offers a dedicated service: OVHcloud Professional Services.

Cost and fees

No termination fees apply. Data migration incurs no additional charge by default. Billing stops when the service is terminated. However, restoring data triggers a pricing change based on the current pricing of the target storage medium.

Retention of data after contract termination

OVHcloud does not retain any data after the service is terminated. Data are irreversibly deleted. A manual export must be performed beforehand to preserve the data. To retrieve their data, customers must first unarchive it, then download it from the restored bucket.
Note: the unarchiving process can take up to 48 hours.
