I agree - I still use DVD media for backup, but I also have all the discs’ contents backed up to a WD 1TB external HDD.
Even with Made in Singapore Verbatim discs, I’m not sure I’d trust DL as a (long-term) backup solution. That’s a personal preference though, as I’ve not kept a DL disc for long enough to tell if they’d last a huge amount of time.
Plus it’s generally recommended, if you’re using any kind of optical media as a storage/backup solution, to use at least two sets of discs, made by different manufacturers. With DL media, that could turn out to be quite expensive.
