I’d like to store/seed important data (wikipedia, gutenberg, etc.), and read recently that it would be a good idea to store torrent files long-term. My questions are:

1. Is it better to store torrent files or magnet links?
2. Will a given magnet link retrieve the exact same .torrent file every initiation?
3. Is storage of these files/links a good idea (especially if I have the files)?

This question is really about whether magnet links or torrent files are better to store long term, with a sanity check that this is something that should be done.

I’ve read these two StackExchange posts which were very helpful, and am looking to get more technical opinions and info:
