Replication to a DD system fails with an authentication error

A replication job might fail with the error The backup copies cannot be replicated because the username and password for the source storage system are not valid or cannot be detected. This failure might happen intermittently, while most backup and replication jobs complete without failure and DD systems are successfully discovered. To resolve this issue, perform the following steps:

1. Collect a DD support bundle and search /ddvar/log/messages for Failed password or Invalid user.
   NOTE:For instructions on collecting the support bundle, see the DDOS Administration Guide.
2. If the search text is found, you see entries similar to the following:

   Oct 15 16:36:26 <DD hostname> sshd[25116]: Failed password for sysadmin from <IP address> port 55351 
   Oct 11 11:18:00 <DD hostname> sshd[31750]: Invalid user <username> from <IP address> port 64425

3. Locate the asset-source host using <IP address> and correct the credentials that it is using to connect to the DD system.
