  • Honestly, given that they should be purely compressing data, I would suppose that none of the formats you mentioned has ECC recovery nor builtin checksums (but I might be very mistaken on this). I think I only saw this within WinRAR, but also try other GUI tools like 7zip and check its features for anything that looks like what you need, if the formats support ECC then surely 7zip will offer you this option.

    I just wanted to point out, no matter what someone else might say, if you were to split your data onto multiple compressed files, the chances of a bit rotting deleting your entire library are much lower, i.e. try to make it so that only small chunks of your data is lost in case something catastrophic happens.

    However, if one of your filesystem-relevant bits rot, you may be in for a much longer recovery session.
