Before performing GaussDB backup, the database must be in normal status.
To check GaussDB database status,
§ Log into the GaussDB database host.
§ If the database user is not omm user, switch to the omm user with the command su – omm.
§ For GaussDB A database, enable environment variables with the command source ${BIGDATA_HOME}/mppdb/.mppdbgs_profile. (For GaussDB T database, this step is skipped.)
§ Check database status with the command gs_om -t status.
