It should be possible to save/restore breakpoints using a BP_STRUCT. 
According to Octave documentation,


bp_struct = dbstatus ();  # save current breakpoints
dbclear all               # clear breakpoints for this example
dbstop (bp_struct);       # restore breakpoints


However, here is the output of an Octave session which shows that an extra
breakpoint is added at the end of the file for sind.m.


octave:11> dbstop ls
ans = 63
octave:12> dbstop sind
ans = 38
octave:13> dbstatus
breakpoint in ls at line 63 
breakpoint in sind at line 38 
octave:14> bp = dbstatus
bp =

  2x1 struct array containing the fields:

    name
    file
    line
    cond

octave:15> dbclear all
octave:16> dbstatus
octave:17> dbstop (bp)
ans = 2
octave:18> dbstatus
breakpoint in ls at line 63 
breakpoints in sind at lines 38 65
