The digital preservation lifecycle encompasses every stage a digital asset moves through, from object import and metadata documentation to secure storage, ongoing monitoring, and long-term accessibility. For institutions with multiple departments or sites, consistency is essential. When each department follows its own informal practices, institutions risk metadata gaps, undetected file corruption, and assets that quietly become inaccessible over time. A standardized, lifecycle-wide approach, benchmarked against recognized standards, protects holdings and supports collaboration across teams. 

For image files, TIFF or JPEG2000 (JP2) are preferred as preservation masters. JPEG is appropriate only as an access copy and should never serve as a preservation master. Institutions should also generate a checksum, with SHA-256 preferred over MD5 for long-term integrity verification, at the point of capture, and store it alongside the file's metadata record. On the metadata side, Dublin Core offers a common baseline, while CCO (Cataloging Cultural Objects) and CDWA (Categories for the Description of Works of Art) provide more object-specific standards worth adopting for collections data. 

Fixity checks, which verify checksums to detect file corruption, are commonly run annually or biannually depending on collection size. Metadata should be reviewed against your institution's schema on a set cadence as well, with an annual review serving as a reasonable starting point rather than relying on point-of-creation checks alone. Undetected file corruption is one of the most common causes of irreversible data loss in digital collections, which makes a fixed schedule for fixity checks a priority for institutions with limited resources.

A 3-2-1 backup approach means maintaining three copies of each asset, stored on two different storage media types, with at least one copy kept off-site or in a geographically separate location. This approach should follow the "preservation master, access derivative" model, keeping master files stored separately from access copies. For many institutions, the loss of a single, unbacked-up master file represents one of the most damaging and irreversible risks in the preservation lifecycle, making this a strong starting point when resources are limited.

The TMS Suite supports every stage of the digital preservation lifecycle, providing the governance frameworks, standardized metadata, and secure access your institution needs to protect its most valuable holdings. Role-based, configurable access permissions allow registrars, curators, and IT administrators to work within appropriately scoped access, while shared metadata schemas and controlled vocabularies help departments and sites stay aligned. This consistency supports both day-to-day collaboration and long-term institutional accountability, sustaining access for generations to come.
