Archive Backups with [[tar]]

    X= keeps the next level of permissions
    v= verbose
    -- delete= deletes any files inside the file this will be copying to
    --exclude= excludes `file/this/*, andfile/that/*`
    /home= location of files you want to back up
    /mounted= the backup drive location

sudo rsync -aAXv --delete /home /mounted/backup/wallserver/
sudo rsync -aAXv --delete /root /mounted/backup/wallserver/
sudo rsync -aAXv --delete /var /mounted/backup/wallserver/
sudo rsync -aAXv --delete /usr/local/bin /mounted/backup/wallserver/
sudo rsync -aAXv --delete /usr/local/sbin /mounted/backup/wallserver/
sudo rsync -aAXv --delete /srv /mounted/backup/wallserver/
sudo rsync -aAXv --delete /opt /mounted/backup/wallserver/
sudo rsync -aAXv --delete /mounted/main /mounted/backup/wallserver/

>Then, we use _**rsync-path**_ to make _rsync_ works with the sudo.
