Therefore, both can achieve the same compression ratio (and similar speed) but using either of them requires users to download the appropriate tool. So, Gentoo user, would you like to know about lzip? Let’s try to get a few fair points here.įirst of all, it should be noted that the two competing projects are two different implementations of the same compression algorithm - LZMA 2 ( correct on : Antonio Diaz Diaz pointed out that LZMA2 is purely an additional container on top of LZMA so: lzip is container on top of LZMA, while xz is container on top of LZMA2 which is a container on top of LZMA), and they use incompatible file formats. As he says, «surely every user of ddrescue would like to know about lzip ». Instead, he decided to take advantage of his administrator position in the mentioned GNU projects and discontinue providing non-.lz tarballs. It seems that he has finally decided that advocacy will not help his pet project in gaining popularity. And it was used mostly by the projects Diaz was member of. However, they were never able to provide any convincing arguments to the community, and while xz gained popularity lzip stayed in the shadow. Over the past five years, Antonio Diaz Diaz, lzip’s author, and a few project supporters were trying to convince the community that the lzip format is superior to xz. And the two projects co-existed silently until lately… However, it never got any real attention and when xz-utils was released as a direct successor to lzma-utils it became practically redundant. Long story short, lzip was created before xz as a response to the limitations of .lzma format used by lzma-utils. You can read some of the background story in New Options in the World of File Compression Linux Gazette article. It’s been around for a very long time, and it never got any real interest.»
«Is this some new fancy archiver?» you may ask. Some of you may already have noticed that sys-apps/ed and sys-fs/ddrescue packages started pulling in lzip archiver. Note: LZMA is the compression algorithm used by 7zip and xz.(update on : please note that this post is outdated and no longer adequately expresses my attitude towards the two competing formats) Some nice benchmarks on these algorithms can be found here. 7zip and xz can be used when space is a concern and compression/decompression speed is not. I would recommend using gzip when less memory is available, and compression/decompression speed is a concern. Xz and 7zip are known to have a better compression algorithm than gzip, but use more memory and time to compress/decompress.
#Lzip vs xz windows
Tools to compress/decompress xz and gzip files are also available on Windows systems, but are more commonly seen and used on UNIX systems.
#Lzip vs xz zip
In terms of availability, zip is widely available across UNIX (Linux/BSD/MacOS) and Windows systems. It is used to bundle files together so that they can be compressed by a compressor that is only able to compress a single file. In short, a single file that consists of one or more files.
#Lzip vs xz archive
tar is short for Tape Archive, and is used to create archive files. I first want to clarify that, of the list you provided, tar is the only one that is not a compression algorithm.
