In a similar way to .gitignore, is it possible to do that a .tarignore file in a subdirectory makes it excluded from archive when doing
tar cfjvh backup.tar.bz2 .
(I know the --exclude parameter of tar but here it's not what I want).

You can exclude directories with --exclude for tar. To clarify, you can use full path for --exclude.
We can exclude directories by using the help of “path“, “prune“, “o” and “print” switches with find command. The directory “bit” will be excluded from the find search!
Tar GZ files are most commonly used for: Storing multiple files in one archive. Sending and receiving larger files in a compressed format. Compressing single files to store locally.
When reading from an archive, the ' --dereference ' (' -h ') option causes tar to follow an already-existing symbolic link when tar writes or reads a file named in the archive. Ordinarily, tar does not follow such a link, though it may remove the link before writing a new file.
Using the --exclude-ignore=.tarignore option causes Tar to use .tarignore files in a similar way that git uses .gitignore files. Use the same syntax as you would usually use in .gitignore files, so if you want to ignore all sub-directories and files in a particular directory, add a .gitignore file with * to that directory. For example:
$ find dir
dir
dir/a
dir/b
dir/c
dir/dir1
dir/dir1/1a
dir/dir1/1b
dir/dir2
dir/dir2/2a
dir/dir2/2b
$ echo "*" > dir/dir1/.tarignore
$ tar -c --exclude-ignore=.tarignore -vjf archive.tar.bz2 dir
dir/
dir/a
dir/b
dir/c
dir/dir1/
dir/dir2/
dir/dir2/2a
dir/dir2/2b
If you want to ignore all directories that have an empty .tarignore file, take a look at the --exclude-tag-all=.tarignore option.
$ find dir
dir
dir/a
dir/b
dir/c
dir/dir1
dir/dir1/1a
dir/dir1/1b
dir/dir2
dir/dir2/2a
dir/dir2/2b
$ touch dir/dir1/.tarignore
$ tar -c --exclude-tag-all=.tarignore -vjf archive.tar.bz2 dir
tar: dir/dir1/: contains a cache directory tag .tarignore; directory not dumped
dir/
dir/a
dir/b
dir/c
dir/dir2/
dir/dir2/2a
dir/dir2/2b
Also take a look at the --exclude-tag= and --exclude-tag= options, which are variations which have slightly different behaviors.
