What is archiving? Solved

Question

Hello,
I would like to know what archiving data means?
So can we archive on the same PC,
and what is the usefulness of archiving?
I read in some courses that archiving in Unix is done using the tar command and I understood the archiving commands well...
But my problem is that I don't understand what archiving is
and what is the difference between archiving and backing up
and another thing, how do they say for example: back up /home to another directory??????
So what is the purpose of archiving????
Well, I hope I receive good explanations.
Thank you in advance.

Hi,
archiving is when you compress a file or multiple folders together, for example ZIP or RAR archives; there are software specialized in this action. As for backing up, it's simply putting files securely, whether compressed or not, in another folder for safekeeping. This means on another hard drive or a USB flash drive.

Hello,

as Kentin said, archiving is about compressing a file.
For the different archive formats and how to create them (via command line): http://doc.ubuntu-fr.org/archivage?redirect=1
To create them graphically, it's as simple as: select the files > right-click > "create an archive"

archiving amounts to compressing a file.

Uh... compression is not mandatory. The "tar" command under GNU/Linux does archive files, folders, or directories, but does not compress them in any way. For that, you need to use a specific program such as gzip, compress, or others.

Hi,  I would like to know what archiving data means?  If you think of files as loose sheets and directories as books, archiving means putting everything together. And that was done before computers existed ;-)) (that's the principle)  In computing, there are software programs to do this (bringing together files and directories).  So basically it's a compression but with a rate of 0 No, it’s not compression, it’s just gathering files without any compression.  In short, there are archives - uncompressed - compressed  -- 106485010510997108

To summarize:
The "tar" format is an archiving format. It allows for having a single file that can contain multiple files, folders, and a complete hierarchy of subfolders and files.
The "gz" format is a compression format. It allows to make a file smaller and to recreate the original file. The same goes for the "gz2" format, which is more efficient.

And a .tar.gz is a folder that has been put into a tar (to have a single file, which is more convenient), then this file has been compressed with gz to take up less space.

By the way, when opening a .tar.gz on Windows with 7zip, there are two steps: one to decompress the gz, and one to open the tar and place each folder and file in its right place.

The "zip" format is an open format that does both in one: archiving and compression.
The "7z" format is also an open format, but more efficient.
The "rar" format is also proprietary. Therefore, it is extremely impolite to make a file in the "rar" format public, as it requires specific software to open it (no one except for the company that designs it knows how it works).

Re,

Please note that all extensions
.tar
.tar.gz
.tgz
.tar.bz2
.tbz2
.gz
.bz2
etc.

are merely conventions to indicate in advance what type of archive it is.

We can simply create them without the extension, but in that case, we will have to use the file command to identify the type of archive.
In this case, of course, it's better to stick to this convention ;-))

L'archivage est le fait de classer dans un ordre bien déterminé que l'on aura choisi : soit numérique, soit alphabétique. L'ordre peut être croissant ou non.
