Did /backup also accessible by your sd ? like a traditionnal 0755 permission ?

In case of mountpoint ( example for /backup/server1 ) if you put 0777 before 
the mounting
it will change after the disk mount. Double check you have the good right.

If it's the mount point you can also try to force the uid ( username ) with 
option in fstab (see man for that) to give
the ownership to your bacula user.

In my case I've the /media/saves owned by root and mounted traditionnally by 
entry in fstab.
I always create a subdirectory inside this one to FS_BACULA which is owned by 
bacula-sd:disk and backup are stored inside.

This allow me to protect /media/saves to be filled by error by bacula in case 
of mount error .
The sd couldn't find it's base path and will fail without writing anything.
