# 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

| **Data Immutability**            | Ability to make data immutable for a defined or indefinite period (WORM). | S3 (Object Lock)  | **Incoming**: Source must support S3 data immutability. <br /> **Outgoing**: Export possible, but target must support S3 locking or require manual adjustment of immutability policies.                                                             | [Cold Archive offer documentation](/en/guides/storage-and-backup/object-storage/overview.md) |

## 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](https://partner.ovhcloud.com/en-gb/directory/).

OVHcloud also offers a dedicated service: [OVHcloud Professional Services](https://www.ovhcloud.com/en-gb/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.
