Windows defaults to locking open files.  And samba only gives you a 
"client's eye" view anyway, so it won't preserve ACLs or other special 
attributes that you might need to to a full system restore.  You should 
either plan to do a new system install followed by dropping your own 
data back from backuppc, or do periodic system image copies with 
something like ghost or clonezilla to give you a starting point, or use 
a more elaborate scheme like the 'open file' link here:
