What do you mean by "glitch"? Irrespective of whether you use --delete
or --delete-after, deleted files on the source are deleted on the
destination once your rsync is complete (which is what I'd assume you
want when you want an exact copy). I'd presume if you're ok with that,
you are also fine with the deletion happening earlier in the rsync
process?
If you're concerned about accidental deletions, you should just not use
any of the `--delete*` options (and give up on the exact copy
requirement). You can look at alternatives to bare rsync that keep
track of multiple backed-up images (rsnapshot is a very simple wrapper
over rsync that can do this, for example).

You can try using --delete for a couple of runs and see if it actually
affects performance in your situation.

You'll need to define what safety means for you.
