Obnam 1.0 released

That's the only sane answer, furthermore even if old media remained readable and compatible forever, it would *still* be the only sane answer because of the rapidly expanding size of storage-media.

I could keep a dozen 20MB hdds around, or I could store their entire content as a tarball on a single current disc, and have them take up 240MB, or 0.012% of the capacity of one disc.

Then I could add in a half-dozen 500MB hdds from a few years later, a few 10GB discs from a few years later, and 2 or 3 100GB-discs from a few years ago. This adds up to dozens of discs.

Or I could do the sane thing and store all of these as files on a current disc. In sum total they take up about 10% of the storage-capacity of a single disc. And they're instantly accessible if I actually want to use any of the old files.

For security, I have a second copy on a disc in my basement, and a tertiary copy in an online account on a different continent that costs less for a year than the electricity for the old discs would cost.

Why try desperately to keep old storage-media alive when it's not the media but the *data* that has value, and that data is by nessecity trivial in size today ?

Barring exceptional circumstances, *nobody* have digital data from 1993 that aren't trivial in size.
