The advent of next-generation radio telescopes is anticipated to generate data at a substantially higher rate, thereby introducing novel challenges in the domains of data processing and storage. Here we present a concise overview of the current data management of the J\u00fclich LOFAR Data Archive, encompassing the ingestion, storage system, export to the long-term archive, and request chain. A detailed analysis of data access over the past decade has been conducted, along with an estimation of energy consumption. The study has identified hardware-related constraints and software aspects as the predominant data storage bottlenecks. From the analysis, we derived requirements for the future expansion of long-term data storage capacity.<\/jats:p>","DOI":"10.1017\/s1743921325104808","type":"journal-article","created":{"date-parts":[[2026,10,5]],"date-time":"2026-10-05T13:49:01Z","timestamp":1791208141000},"page":"216-220","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":0,"title":["Learning from the present for the future: the J\u00fclich LOFAR Long-term Archive"],"prefix":"10.1017","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-4770-9945","authenticated-orcid":false,"given":"H.","family":"Stiele","sequence":"first","affiliation":[{"name":"Forschungszentrum J\u00fclich"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"Manzano","sequence":"additional","affiliation":[{"name":"Forschungszentrum J\u00fclich"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Miskolczi","sequence":"additional","affiliation":[{"name":"Forschungszentrum J\u00fclich"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"V.","family":"Vybornov","sequence":"additional","affiliation":[{"name":"Forschungszentrum J\u00fclich"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Fieseler","sequence":"additional","affiliation":[{"name":"Forschungszentrum J\u00fclich"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5003-4714","authenticated-orcid":false,"given":"S.","family":"Pfalzner","sequence":"additional","affiliation":[{"name":"Forschungszentrum J\u00fclich"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2026,10,5]]},"reference":[{"key":"S1743921325104808_ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ascom.2024.100835"},{"key":"S1743921325104808_ref1","doi-asserted-by":"crossref","unstructured":"Begeman, K. , Belikov, A. , Boxhoorn, D. , Dijkstra, F. , Holties, H. , Renting, G. , Vermaas, N. , & Vriend, W. 2012, Scaling astro-wise to lofar long term archive.
