Writer DVD changer. Is there such a thing in nature?

Question

Backup

Actually interested in the question. To back up gigabytes of data on a DVD, you need an aggregate to feed it with discs, set a queue for recording directories / isosh and let it write itself. Not a duplicator that writes one thing to all discs, namely to record different things, either in turn or simultaneously.
Has anyone seen this in nature?

Answer 1

to back up gigabytes of data, they use a streamer - it
makes no sense to back up on DVD, it was not and will not be more reliable and cheaper in terms of the ruble / megabyte ratio
