For me I had a stack dvd blanks left over, I decided to save a little bit of money and used them to back up folders of childhood photos, documents etc and place them inside their own jewel cases.
I do have a 2TB external HDD, But that I throw on LARGE steam game back ups and movies.
Sure, the “cloud” exists and I use that too but what if your intewebz goes down, good luck getting your backups until it’s back up.
What do you use? Optical media, tape drives etc?
I prefer optical media if possible. Should survive a few decades, assuming good quality discs.
But I’d much rather use LTO tape if it wasn’t so expensive to get the drive.
DVD’s will last about 15 years tops. I bought the highest quality 100 year rated AZZO dye DVDs. I used special tools from cdforums to make sure I burned at the speed that resulted in the lowest pi/pio errors rate ( the errors you don’t normally see because they’re corrected in drive). The ideal speed isn’t the slowest or fastest based on the drive and the media. I stored the DVDs in black dvd cases in my temperature controlled basement.
They all started having errors after 10 years.
