Hello, can I back up an iPhone and manually move the backup file to some other directory and then put it on a different Mac and use it to restore a different iPhone? (also if my iphone is backing up to iCloud and I factory reset it and sell it, then buy a new iphone and connect it to a different Mac, but using the same apple account would I be able to restore the new iphone from the new mac from the old iCloud account?). Thanks.
