Hi @daves,
As Matt mentioned cbbackup & cbrestore will be deprecated for future releases of Couchbase Server Enterprise Edition since we shipped replacement cbbackupmgr in 4.5 last year. Here is the documentation - https://developer.couchbase.com/documentation/server/4.6/backup-restore/enterprise-backup-restore.html and What’s New in 4.5 - https://developer.couchbase.com/documentation/server/4.5/introduction/whats-new.html.
