In addition, there are standard graphic interfaces for these tools, as well as archive managers, which combine several compression programs – that must be installed as well – into a single visual user interface. Short commands can quickly compress data files, such as HTML documents, to save storage space and bandwidth when sending via networks or the internet. There are a number of free compression tools for Linux distributions that all have one thing in common: they can be operated via command line or terminal. But what are the different compression programs and formats? And why are they still so important today for systems like Linux tar? tar-data files are often compressed with the help of different tools, like gzip, bzip2, or lzop. With the help of tar, files and directories can to this day still be packed into a single data file and then recovered with the user rights still remaining intact – as long as the source and target both support the Unix or Linux data file directories.įor the archiving process to free up additional storage space. To make this archiving method as efficient as possible, the packing program tar (short for t ape archiver) was developed for Unix systems in 1979. For reasons of data security, archiving was an important factor in server environments at an early stage: Originally server data was stored on tape drives – a backup method which is still used for large data volumes. Behind the phrase “data archiving” is the basic idea of backing up files or entire directories and storing them in a secure location, often in a compressed form.
