That likely means you missed or corrupted files in repo/data/...

Did you check the hardware (see our docs about IntegrityErrors).

It's archive metadata (list of all blocks that store information about
backed up filenames, file metadata, lists of file content block
references), not just an index/cache.

No, iirc it should be in check --repair already.

prune is just a time-based delete.
