Hi Karim,
You can rename it to match the filename pattern of an UpdraftPlus database file ending in -db ; and then gzip it, if it’s not already gzipped (use 7-zip if you’re on WIndows). Then you should be able to drag-drop it into UpdraftPlus’s restoration area.
Note that it’ll need to contain SQL that does not hard-code any references to databases. i.e. no statements like “USE my_database” or crazy stuff like “DROP ALL DATABASE”. UpdraftPlus will happily run all the SQL it finds there. So, if it’s got anything hard-coded or crazy, then it will do whatever it is told!
