# OPTIONS
--n, --number=*number*
+-n, \--number=*number*
: set the number of objects to search for during each
cycle (ie. before printing a line of output)
--c, --cycles=*cycles*
+-c, \--cycles=*cycles*
: set the number of cycles (ie. the number of lines of
output after the first). The first line of output is
always 0 (ie. the baseline before searching for any
objects).
---ignore-midx
+\--ignore-midx
: ignore any `.midx` files created by `bup midx`. This
allows you to compare memory performance with and
without using midx.

+\--existing
+: search for existing objects instead of searching for
+ random nonexistent ones. This can greatly affect
+ memory usage and performance. Note that most of the
+ time, `bup save` spends most of its time searching for
+ nonexistent objects, since existing ones are probably
+ in unmodified files that we won't be trying to back up
+ anyway. So the default behaviour reflects real bup
+ performance more accurately. But you might want this
+ option anyway just to make sure you haven't made
+ searching for existing objects much worse than before.
