I’m using couchbase EE 5.1.1

I’m getting the above error. Any suggestions?


I ended up reading the documentation and found out for Enterprise edition there’s backup manger “cbbackupmgr” which is faster more efficient than cbbackup and cbrestore. All it requires is to first configure an empty directory as backup directory. For more information pls read the link below.https://docs.couchbase.com/server/5.5/backup-restore/cbbackupmgr-tutorial.html
