Not every long-term retention requirement involves petabytes of data. Organizations of every size have documents, records, images, research data, intellectual property, completed projects, historical information, and other digital assets that must remain protected after routine access declines.
Keeping all of that information indefinitely on SSD or continuously spinning HDD can mean ongoing power and cooling costs, hardware refreshes, and repeated migrations for data that may be rarely accessed.
The Savartus ELS100 provides a compact, dedicated online optical preservation tier for important information that needs to remain retained and retrievable without a rack-scale library.
Preserve what matters
Selected information can be written to optical media and managed as a long-term preservation copy. Optical media does not require power simply to retain the recorded information, unlike continuously operating disk storage.
The ELS100 is an online optical library, not the integrated-cache appliance offered by ELS150 and ELS300. Where active workloads need cache-backed access, pair ELS100 with a separate SSD/HDD performance tier or existing storage environment. Keep frequently accessed information on storage designed for active use; preserve long-lived information on storage selected for preservation.
Write-once behavior, media type, and supported workflow should be confirmed for the specific media and system configuration. Optical preservation helps create a distinct preservation copy, but it does not remove the need for retention governance, access controls, fixity checks, tested retrieval, or media and reader migration planning.
Designed for long-lived information
An ELS100 retention tier can support business and financial records, completed project files, intellectual property, research data, engineering documents, images and media, historical records, reference datasets, and other material with a continuing retention requirement.
As routine access declines, preserved information need not occupy scarce high-performance capacity for its entire retention life. It remains managed and retrievable through the surrounding storage and information-management workflow when staff have an authorized reason to access it.
Retention without enterprise-scale complexity
The ELS100 brings optical preservation to departments, small organizations, branch locations, laboratories, and professional offices whose collections are important but do not require a large automated library.
Its role is intentionally focused: provide a compact online optical library for a dedicated preservation tier. That gives ELS100 a distinct place alongside ELS150 and ELS300, which combine organizational storage, an integrated cache server, and automatic optical second-copy creation in one appliance.
Real requirements come from the record and the organization
There is no single U.S. retention period that applies to every document, dataset, or organization. The retention authority may be an approved records schedule, contract, grant or repository commitment, regulation, legal hold, or institutional policy. A storage tier should execute and support those decisions, not invent them.
For U.S. Federal agencies, 36 CFR Part 1236 requires electronic-record controls for reliability, authenticity, integrity, usability, content, context, and structure. Agencies must plan to keep records retrievable and usable for their NARA-approved retention periods and plan migration when records outlive the system. These rules apply to Federal agencies managing Federal records; they should not be generalized to every private organization or state/local entity.
For specified SEC-regulated broker-dealers and exchange members, 17 CFR 240.17a-4 defines preservation periods for particular records and permits electronic recordkeeping through either a non-rewriteable, non-erasable format or a compliant time-stamped audit-trail system, subject to access, production, redundancy, and other conditions. An optical library by itself does not establish compliance with the full rule.
For HIPAA-covered entities and business associates subject to the Security Rule, 45 CFR 164.316 requires retention of specified security policies, procedures, and documented actions or assessments for six years from creation or when last in effect, whichever is later. This is not a general six-year medical-record or PHI retention mandate.
ISO 14721, the Open Archival Information System (OAIS) Reference Model, offers a conceptual framework for thinking about archival information packages, preservation description, access, and long-term planning. It is a reference model, not a regulation or an ELS100 product certification.
A practical preservation workflow
Begin by identifying which record series or project is being preserved, its owner, authoritative source, approved retention schedule, restrictions, and disposition authority. Preserve descriptive and administrative metadata that allows staff to find the object and understand its context.
Define how content is ingested, how integrity is checked at receipt and retrieval, who may access or export it, how legal holds suspend ordinary disposition, and how restore tests and media migration are documented. Preserve relationships among source files, derived copies, and related records.
For federal records, Part 1236 specifically treats storage media as only one part of electronic records management: recordkeeping controls, associated metadata, retrieval, access, disposition, and migration planning remain necessary. For other environments, apply the organization's governing schedule, award, regulation, and policy.
Preserve information beyond the system that created it
Applications, storage platforms, vendors, and media generations change. An important record may outlast all of them. A compact preservation tier can reduce reliance on keeping every long-retained file on continuously powered performance storage, while a defined stewardship process keeps the information discoverable and usable.
Technology changes. Information persists.
