the current plugin (founded in about 2014) is only capable of "ZIP" formatted archives.

in the meantime a lot more advanced options have been created.

these are namely: bz, bz2, gzip, 7z/xz, zipx - and others.

i personally feel like ZIP as it is used now does not even allow symlinks - so e.g. when storing library folders this is likely to store groups of large but many-fold identical files.
other than that i am not that sure if ZIP preserves (or is capable of preserving) all unix provided file system attributes correctly.
