Fixed syntax error (#8732) 

* Fixed syntax error

Last edit to the REPLICA_ID command introduced a syntax error by adding an extra ')'. Removed it.

* Fix replica ID setting examples

- Accept suggestion from @thajeztah based on product testing
- Apply change to page examples
- Remove NFS backup example based on the following errors: 
tar: /var/lib/docker/volumes/dtr-registry-nfs-36e6bf87816d: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors
