Hi,

When I’m trying to take data backup from couchbase VM using the below command

cbbackup -v http://...:8091 /opt/couchbase/backup -u Administrator -p ******. I’m getting the below error.

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

I am also facing the similar issue, but i didnt find any suggestions on this.

the ‘path’ variable doesn’t have a value. It would be useful to show the command line used.
