I don't think these files as such are corrupted. They are decompressible (to
identical contents). I wouldn't trust the backup(s) as a whole - they may be
missing files for instance - but that's a different matter.

I admit that I am missing the point why you are going to the trouble, but to
answer your question: it doesn't matter. BackupPC will add the checksums at
the appropriate time (next backup, I'd say) if they are missing (and enabled).
That said, I'd expect the version with checksums to be larger, because the
compressed content should be identical. Add to that the checksums in one case
and nothing in the other.

Holger
