Hello @prasanpd,

Sorry to hear that you’re having issues with backups. To help debug this further can provide the following:

  • The version of Couchbase Server for both cbbackupmgr and the cluster.
  • A snippet from the backup logs at the time.
  • A snippet from the memcached logs at the time.

Kind regards,
Patrick
