The article talks about tar.gz for archival, which is scary considering none of tar.gz, tar.xz, tar.zstd are safe formats. Try corrupting a few bytes in the middle and half the archive is lost, even files untouched by the corruption Repair tools only exist for tar.bz2 and tar.lz, but neither gets much use compared to gz/xz. The most safe compression for tar is something that splits the compression into blocks, such as btrfs compression or LTO tape compression
