Problem

Argument errors for solana-validator v1.17.0 & v1.17.1 specifying '--snapshot-archive-format '

Running v1.17.1 produces error for any mentioned archive format lz4 or zstd - error: 'none' isn't a valid value for '--snapshot-archive-format <ARCHIVE_TYPE>' [possible values: lz4, zstd]

Running v1.17.0 gives error: The argument '--snapshot-archive-format <ARCHIVE_TYPE>' was provided more than once, but cannot be used multiple times

Summary of Changes

return back line for "tar" | "none" => Some(ArchiveFormat::Tar),

Fixes #
the command line argument for lz4/zstd needs to be accepted as well

Running v1.17.1 produces error for any mentioned archive format lz4 or zstd - error: 'none' isn't a valid value for '--snapshot-archive-format <ARCHIVE_TYPE>' [possible values: lz4, zstd]

The options none / tar / bz2 / gzip were removed intentionally per #33484; the only options we will support in the future are lz4 and zstd. The change to disallow these types was first introduced in v1.17.1, so that is why you don't see the same error in v1.17.0. I have personally verified that passing zstd or lz4 works with v1.17.1, as does not specifying --snapshot-archive-format at all

Running v1.17.0 gives error: The argument '--snapshot-archive-format <ARCHIVE_TYPE>' was provided more than once, but cannot be used multiple times

That error is unrelated to version and is telling you directly what the problem is - you specified that argument more than once.
