Operational Excellence in Archiving and Preservation

Eclair Préservation, is the industry leader in France and beyond when it comes to preservation and archiving services. In its position as the oldest film lab in France, Eclair Préservation currently manages a massive collection of 157.897 digitised items for a total of 17PB of digital media and counting.

Eclair Préservation’s mission is to allow their customers, predominantly in media and entertainment, to securely preserve, expose and monetise digital and analogue assets. Given the sheer volume, Eclair Préservation was obliged to industrialise its Media Asset Management (MAM) operations, thereby eradicating manual work. As a result, Eclair’s customers can now directly access several key Media Asset Management (MAM) functions without further intervention from a servicing department.


  • More transparency: a customer base of 180 high-end producers and counting directly interact with the MAM solution made available to them by Eclair Préservation
  • No-code workflows: 50 workflow templates with each several parameters provide unlimited functionality to operators and archive producers
  • Storage: a wide range of 10 different storage options and configurations allow customers to seek an optimal balance between cost and performance
  • Time saved: 13.750 hours or 2000 days of otherwise manual work per year

The Needs

Eclair Préservation serves diverse clients with a wide range of preservation services and archive operations. The purpose of archive operations is to help customers manage and exploit their inventory.

Prior to using Limecraft, Eclair Préservation used an in-house developed MAM solution. Various issues hampered smooth operations, including excessive manual work and inconsistent data. Thus it was difficult to retrieve and reuse material. To overcome these challenges, Eclair Préservation set out on a mission to deploy a novel MAM approach, using a hybrid storage architecture, i.e. on-premise storage linked to a cloud-based workspace. The reason for this approach is clear: the security liability and the cost of forklifting and managing several petabytes of storage in the cloud is prohibitive. Yet exposing assets on local storage via a cloud-based workspace allows them to engage and collaborate directly with customers, eliminating the need for a complementary servicing department.

Long-term objective

The long-term objective was to create a dedicated workspace for each customer of Eclair Préservation using a customised ‘consultation’ profile. Customers can follow up on the day-to-day operations executed by Eclair Préservation, which commands superior data quality and maximum operational excellence. Therefore collections are only exposed after several iterations of semi-automated data cleaning and verification.

Eclair can expose a preservation workspace to each customers in the shortest possible timeframe. Using Limecraft, and relying on its ability to jumpstart a workspace based on pre-defined production templates and workflow profiles, new subscribers onboard in a matter of hours, rather than days or weeks, and at marginal cost.

To achieve this, several key steps must be completed in the proper order before exposure, including but not restricted to the reconciliation of different sources of metadata, data cleaning, indexing, and eventually digitising the item. These processes are automated to a large extent using the no-code workflows engine of Carrick-Skills, supervised by skilled Eclair Préservation operators. The standard workflow involves ingesting the data, conducting a thorough cleaning process, and finally exposing it to the public via the Eclair workspaces.

The Challenge: how to scale to Millions of Items?

The specific choices taken by Eclair Préservation were driven by two key requirements. First and foremost, a hybrid (on-premise and cloud-based) operating environment was essential to expose media on local storage via a cloud-based workspace to avoid excessive transcode and file transfer operations. Secondly, Eclair had to look for a solution that had the potential to scale to very large numbers of users and managed media. Therefore the ability to rapidly onboard new customers and large cohorts of users at marginal cost was a critical success factor.

Limecraft has been offering hybrid storage operating environments since 2013. Original media, often in high-resolution, are typically hosted on storage managed by the customer, who has the freedom to operate to use cloud-based storage optimised for large volumes, cold storage on-premise, nearline storage, or a combination of these. Web proxies are used in the online workspace for logging, archive production, pre-cutting, and collaboration in general. Upon export to post-production, Limecraft can securely access the media stored on such local storage end executing a partial retrieve. This approach creates significant savings in bandwidth and online storage consumption. It helps the customer minimise the number of complementary transcodes and file transfers. And, because it is a tightly controlled environment, despite great accessibility, it is much more secure compared to any other alternative.

“What I appreciated about both Carrick Skills and Limecraft was their attentive and responsive approach. They truly understand our needs and concerns”, says Laurent Nikolli, technical director at Eclair.


The second point is equally important. Given the very large numbers of assets and users, scalability was a critical success factor. Hence the need for a commercial model whereby the number of users is not factored in. More subtly, new customers have to be onboarded and content operations have to be executed with minimum human intervention. Rapid deployment is possible due to the use of pre-defined “boilerplate” workspaces. These workspaces guarantee compatibility with all sorts of file formats including DCP and IMF, and the underlying no-code workflow system by Carrick-Skills is equipped with more than 50 workflow templates that can be easily replicated. Finally, as suggested above, the possibility to store the bulk of the original media on local cold storage, allows Eclair to scale to several hundreds of petabytes of storage.

💡What is a boilerplate workspace or workspace template? A workspace template is a generic workspace with pre-defined settings that can be easily replicated to save the time of starting a new workspace from scratch. It reduces the time for deployment of a new production from days to hours. Pre-defined settings may include but are not restricted to the following settings: encoding parameters, metadata models, cron jobs, 3rd party interactions, etc. More info

“Limecraft understood our requirements very well and delivered a solution fit for the purpose to Eclair Préservation,” says Stéphane Ewbank, responsible for digital activities at Eclair Preservation.

The Business Case

“While the scope of work was enormous and the solution we were looking for was truly innovative, the project was brought to success by dividing it into smaller and manageable parts. More like agile development. An incremental approach, whereby each delivery created new opportunities and new operational advantages, allowed us to validate and further improve the business case step by step” according to Edouard Prévost, co-founder at Carrick Skills

Using the agile implementation method rightfully adopted by Eclair Préservation, Limecraft and Carrick-Skills connected to the ERP system, retrofitted existing thesauri, critical to efficiently navigating content in large workspaces. The solution offers 10 different storage options, allowing subscribers to balance cost and performance. And Eclair Préservation offers semi-automated data migration and housekeeping processes, supported by AI and whereby minimum human interaction is incurred. So eventually achieving the goals of digitising and exposing inventories, at marginal cost and without the substantial intervention of a service department

Today, Eclair Préservation serves over 180 clients using the system; 40 more are scheduled for onboarding. With more than 50 parametrised workflows, each with five or more parameters, the possibilities are endless.


By choosing Limecraft and Carrick-Skills as the foundation for their Media Asset Management operations, Eclair Préservation was able to deploy a solution which is infinitely scalable in terms of the number of users and the size of the inventory. Additional media, customers, and workflows can be hosted at marginal cost, due to the hybrid on-premise – cloud-based operating environment and the ability to use boilerplate workspace templates to jumpstart new customers.

The industrial approach eradicates manual work, which is a key enabler of said scalability. As a by-product of choice to allow customers to interact directly with the content operations, Eclair was forced to raise the bar in terms of operational excellence.
