You need to think wider than just the disks then.I need to back up some important data that I want to keep forever
You need to think wider than just the disks then.
I'd be looking at:
1) Putting a checksum file on the disk with the data
2) Backing it up to more than one disk and use different brands for each.
3) Regularly checking that the contents of the checksum still match what can be read from the disk
4) Possibly even replacing the disks with fresh copies every 3-5 years.
