DB backups directory should be moveable

[ChemicalSailor]

Saving DB backups in the uploads directory is a reasonable default but there should be an option to save them elsewhere (e.g wp-content/revisr_backups/). In my environment I have uploads ignored by git hence mysqldump are also ignored.

Thanks for the suggestion. I'll definitely look into adding a filter for changing the directory for the next release.

[ChemicalSailor]

That sounds great. When you say filter do you mean using the add_filter mechanism? Defining a constant in wp_config would be better.

[mattgrshaw]

Good point. I'll make it a constant.
