Due to the strategic importance of the files stored, the maximum retention period is defined at 35 years. The retention period can be configured by the users when uploading files and the system immediately gives a predicted cost calculation for the selected period. In the background, over time, documents are being ‘downgraded’ to cheaper storage types and eventually get deleted at the end of their retention period.
It was a main requirement for the solution to be highly scalable adapting to the growing needs of our users. This and the planned future extensions also meant that the project needed even more throughout documentation, specification and test cases than usual.
Handling pdf, zip, ppt, xlsx, xlsm, txt, doc, CAE, engineering data files as well as data objects with unspecified file types. Detailed metadata is added to every file during upload and this provides the basis of the built-in advanced search function.
Even though the size limit for a single batch upload in the web app is maximized at 5GB, we needed to provide a mass file transfer and migration option that can also import legacy files from previous systems. This can be performed through a different interface and for that the one off transfer size is 200TB.
