Error backing up cluster: internal server error

Couchbase Server
1

The cbbackupmgr is not working on Couchbase 7.6.0 CE. When I run:

/opt/couchbase/bin/cbbackupmgr backup -c 127.0.0.1 -u user -p pass -a backup -r cluster

Error:

Error backing up cluster: internal server error executing 'GET' request to '/api/v1/bucket/wizarder/backup': {"_level":"exception","caller":"datastore:894","code":18040,"key":"dictionary.system_collection","message":"Error accessing system collection - wizarder"}

Which cbbackupmgr are you using?

/opt/couchbase/bin/cbbackupmgr --version

cbbackupmgr version 7.6.0-2176 (8eeaccdf)

Ok - I can reproduce it. I opened a ticket MB-61333

Create the archive with disable-bucket-query…

cbbackupmgr config --archive /home/ec2-user/cb_backup_20240328_3 --repo testrepo1 --disable-bucket-query

cbbackupmgr backup --archive /home/ec2-user/cb_backup_20240328_3 --repo testrepo1 -c localhost -u Administrator -p ‘password’
