Nothing special required. This statement might be misleading in this particular case Marco described. Bacula will be able to run incremental backup but if the mountpoint is changing every time backup is running, the content of the mountpoint directory would be fully copied over and over again, thus, taking more space compared to the incremental backup of the same directory. As I said in some post, it might be avoided by using bind-mount option of the mount(8). Regards! -- Josip Deanovic
