Re: Floppy disks at 2021?!
Maybe backup your files on the cloud - S3, Google Cloud, Linode. But also there I don't know what will happen in 50 or 500 years. אורי u...@speedy.net On Sun, Dec 26, 2021 at 11:03 AM wrote: > On Saturday, 25 December 2021 3:22:22 IST Steve Litt wrote: > > said on Sat, 25 Dec 2021 03:13:54 +0200 > > > > >Until this thread I didn't even know there was such a thing as 8" > > >diskettes.

I can't pin the degradation on a brand or a cd type: I had cd's from 1999 that worked but cdrs from 2009 had failed. My sample size is also quite small. In my last restore session I had no more than 120 cdrs, and maybe 40 DVDs tops, previous restore was in the 200 cdrs range. My cdrs had been both hybrid and regular ones (but vast majority was just data), I normally went with CD and not CD-RWs. > for details. > > I also wrote about my objections to cloud backup.
