tar.zip error during save

I made a save script, to save some directories in my /home. To do that I loop through the directories in /home, and launch a save for each of them.

These directories contain jar files, and some .txt. Properties and other directories. The first time I launch the script it worked great. I modified it, but yesterday when I try some feature it goes wrong and I can not find why.

I have this error when I use the tar -cjf command to create .tar.zip archive.

tar: home/myFolder : impossible stat: no file or folder of this type

backupdate=$(date +%Y-%m-%d) 
dirbackup=/save/$backupdate 
mkdir $dirbackup 
list_dossier=`ls ../home`

for server in $list_dossier 
do

    tar -cjf $dirbackup/$server.tar.zip home/$server

done

EDIT I’m trying to keep this shape of save : a folder with name the date, and in it, X archves contain my X folders of my /home

#!/bin/bash
backupdate=$(date +%Y-%m-%d)
dirbackup=/save/$backupdate
mkdir $dirbackup

for server in /home/*
do
    echo $server"test"
    tar -cjf $dirbackup$server.tar.zip $server

done

exit

Answer

This line will cause problems:

tar -cjf $dirbackup$server.tar.zip $server

That’s because $server would be something like /home/myserver and so this command would expand to

tar -cjf /save/2019-04-13/home/myserver.tar.zip /home/myserver

Note the extra /home in the path to the tarfile.

Instead we can change directory before hand..

#!/bin/bash
backupdate=$(date +%Y-%m-%d)
dirbackup=/save/$backupdate
mkdir $dirbackup || exit
cd /home || exit

for server in *
do
    echo $server"test"
    tar -cjf $dirbackup$server.tar.zip $server
done
