WP-Sweep is meant as a all in one and you can’t customized it. If it is deleting your post format, I recommend you to not used it.
If I am not wrong, post format is stored in the wp_postmeta (if not you can provide more technical details). If WP Sweep is deleting it, it means that the post meta is tied to a post that has been deleted.
It’s actually changing the post format from a Link to Standard.
These are custom posts created from the Viba Portfolio plugin:

The posts themselves aren’t deleted.
It might be possible that post meta is not linked to any post? Do you know which Sweep is actually causing it to be deleted?
No idea which Sweep is actually causing it to be deleted – I did go and have a look.
I’ll ask my dev guy about it.
