Restore whatsapp media

My whatsapp media was locally deleted by a cleaning app. I have a backup in google drive from after the cleaning. I was wondering if the lost data is in this back up, or do i have to use a previous backup that is saved on my device.
Maybe i should mention that i can see the data in google photos, as all my photos are backed up on the cloud, whatsapp just cant seem to be able locate these photos (they look blury and i cant open them)
Also, if I delete whatsapp and reinstall it, will the local backups still be available? (The queation is - will the whatsapp folder still exist?)

Thanks
