I did a new Backuppc's installation with your suggestions.

But when I tried to start backuppc, I had the same response :

Job for backuppc.service failed because the control process exited with error code. See "systemctl status backuppc.service" and "journalctl -xe" for details.

What could I try next to solve the problem ?
Thanks

Something wrong with permissions...

I used this method : sudo service backuppc stop sudo mkdir /media/edith/Disque640Go/backuppc/ sudo rsync -va /var/lib/backuppc /media/edith/Disque640Go/

  This should have been -vaH to preserve hardlinks.   And it may take
a long time.

sudo mv /var/lib/backuppc /var/lib/backuppc_origine sudo ln -s /media/edith/Disque640Go/backuppc /var/lib/backuppc sudo chown -h backuppc:backuppc /var/lib/backuppc

  This should have been chown -r  to recurse down the tree.
