Hmm my experience with DVD storage is mostly negative. They were all put in cases in closed shelves but after ~10 years there were either unreadable or with errors. I know there are DVD-Rs that are specifically rated for archival but most are not.
Here are the most common mistakes people used to make when writing DVDs:
By following these precautions I still have 20-year old backup DVDs that I can read without a problem. In fact most of my CD blanks have survived and are readable โ and the ones that didn't owe it mostly to scratches (CDs were a lot more delicate than DVDs and nowhere near Blu Ray durability).
Check them regularly and mirror them. They are basically only beaten by tape drives in terms of longevity. Do not under any circumstance use 1 copy of a DVD for backups. Consider this to be a RAID system. They stand the test of time but not the test of being in a moving box or under a hammer.
