- ghusbands 6y agoIt's only a file encoding if you do it per file, but that removes a lot of the advantages of sharing and minimising the recovery data. PAR is usually across multiple files/blocks, but then you've got to manage this extra data when any part of any of those files/blocks changes. The more complete/parallel your recovery data is, the more you need to update on even a small change to one file. There'd be all sorts of ways to make it more efficient, but it would take some analysis to work out the best trade-offs.
