Sometimes we use /home/backup mounted on a special block device dedicated to backup. Often simply /home partition.
But, if the mount point is not mounted, and there is no /home partition, /home/backup will be a folder on the root / partition.

We should detect that, example:

root@temp:/home# df -h /home/backup/
Filesystem      Size  Used Avail Use% Mounted on
/dev/vda1       109G  4.8G   99G   5% /

We can see that /home/backup is in fact /.

If we detect that, we should not do any LOCAL_TASKS and echo an error message that will appear in the cron output.

Sur Linux on peut faire stat -c '%m' /home/backup et voir si ça retourne /.
Sur OpenBSD stat -f '%Sd' /home/backup.

On fait ça dans evomaintenance : https://gitea.evolix.org/evolix/evomaintenance/src/branch/master/evomaintenance.sh#L177
