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

Subject: Re: [Dspace-tech] large video files in dspace
Hi Tint,
We are thinking of storing big video files (1G or 2G) in dspace and have a
few questions.
1) Since submission can be done using batch importer at backend, I think
submission is not likely an issue. But anybody ever experience any issue
uploading large files?
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? (user population is not big... only about
100)
Is the intention for 'users' to view the files? 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. Considering that, is it
advisable to split them?
I'd appreciate if anyone can share the experience of such big files with
dspace.
In DSpace, bitstreams are just files on disk. 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.
Thanks,
