I listed all the criteria you mentioned and met it with a gzip archive.
furthermore, gzip refers to them as archives.
https://www.gnu.org/software/gzip/manual/gzip.html
Usage: gzip [OPTION]... [FILE]...

Mandatory arguments to long options are mandatory for short options too.

-f, --force force overwrite of output file and compress links
-h, --help give this help
-k, --keep keep (don't delete) input files
-l, --list list compressed file contents
-L, --license display software license
-n, --no-name do not save or restore the original name and timestamp
-N, --name save or restore the original name and timestamp
-q, --quiet suppress all warnings
-r, --recursive operate recursively on directories
--rsyncable make rsync-friendly archive
