Your class seems to be very good, but
I have this error :"Fatal error: Uncaught Error: Using $this when not in object context in \vendor\coderatio\simple-backup\src\SimpleBackup.php on line 442"
when I try to save only some tables of my database.
It seems that excludeTables and includeTables methods doesn't work fine.
I do not experience this issue when I save the whole database.
Do you have any idea ?
