7. Describe the issue:
After the configuration, when I start running the pgbackrest its giving me a unknown error that --pg1-local option is invalid, I didn't mention such option in config, also there is no such option from doc as well.

Looks like you did not upgrade all your hosts to 2.30. Yes, this is a bad error message and we are working on it.

[cmwshang]

Although it is likely all your hosts did not get updated, your configuration also looks a little strange. It appears you have a standby and a primary but the standby stanza configured is [cluster] but on the primary it is [cluster_pg] and where is your repo-host?

[sujithtee]

It is cluster_pg only in master and standby. During the deletion of confidential information I deleted it by mistake. Updated the question now.
Earlier I had 2.29 on master and standby and faced the same issue, now standby is only on 2.30. do I need to upgrade master and check?
Also We didn't mention repo-host in any of our other implementations and working fine(version 2.13 and 2.17), we have a NFS.

[dwsteele]

When pgBackRest is operating among multiple hosts the versions must be the same. It's OK if a unrelated cluster is using a different version.

Thanks for the comments. Working fine after installing same version on both master and standby.
