Question

The default dump.rdb file is created redis saves to disk, and the default ownership is redis:redis with 660 permission. This is refershed everytime redis performs automatic backups.

How are you starting redis? I have a /etc/init.d/redis-server script which is below.
You can set the $USER and $GROUP to run the redis binary as. When doing a dump Redis will use these user+group permissions.
