That division of data into blocks with redundancy to cope with some 
proportion of missing/damaged blocks is called an “erasure code”. E.g. 
fountain codes <https://errorcorrectionzoo.org/c/fountain> provide this 
sort of function.

That’s orthogonal to packing up files into an archive and applying 
compression, though. It can be useful to have one without the other.

I was looking through the standard Debian repo for some utility that 
provides such redundant segmentation, and I couldn’t find one.
