Hi Stuart Thanks very much for the explanation. Another question (this is an issue with another repository): we have some records in our repository with links to video files on our streaming server. Now, we want to archive those files in dspace. I'm aware that we can upload additional bitstreams to an existing record from front end. But how can I do it from backend? Export item and then import again? Or is there any other way? Best regards Tint

Files that large can get a bit troublesome over http (via the web interface) if your connection isn't great, but if you are planning on ingesting using the importer, then all that is doing is just a filesystem copy. > 2) Can downloading of such big files be a real problem? any > recommended server specs?

If so, would another option be to make an 'access' copy which is smaller for them to access, while also storing the large 'preservation' copies? > 3) These videos are for long term preservation.

Therefore the only issues you should have are whatever limitations your filesystem puts on storage. Small numbers of large files are usually less problematic that large numbers of very small files.
