English to German Bus/Financial IT (Information Technology)

Mit "duplication" habe ich immer ein Problem. Hier geht es um Information Asset Management:
"Managing information as an asset is no simple task. The sheer volume of information is growing at an unprecedented rate and, as a result, organizations are struggling with sharply rising costs to access, control and store data.But an organization’s inability to deal with ***data duplication****—and put in place a consistent data retention policy—can be even more costly."
Ist damit die doppelte Datenmenge gemeint oder das doppelte Erfassen derselben Daten???
Vielen Dank!
