Fullduplisert

Fullduplisert is a Norwegian-language term used to describe something that has been duplicated in its entirety, resulting in two identical copies. The word combines ful(l) 'full' with duplisert 'duplicated'. It is used in various disciplines to indicate complete replication rather than partial or incremental duplication.

In biology and genetics, fullduplisert can refer to a full duplication event, in which a contiguous DNA region is copied and inserted, producing two identical copies of the segment. Such duplications can affect gene dosage and phenotypic effects, and are distinguished from partial duplications or complex rearrangements. Detection typically relies on sequencing, read depth analysis, and copy-number profiling.

In information technology and data management, fullduplisert describes a complete data duplication or backup of all files and systems to a target location. This ensures the entire dataset can be restored, but requires more storage space and bandwidth than incremental or differential backups.

In other contexts, the term may be used informally to indicate that a document, dataset, or artefact has been copied verbatim in full. The concept is closely related to duplication, replication, and redundancy, depending on the domain.
