Plugin command to initialize a storage plugin for the backup operation.
plugin_executable setup_plugin_for_backup plugin_config_file local_backup_dir
gpbackup invokes the setup_plugin_for_backup plugin command on the master and all segment hosts during gpbackup initialization phase.
The setup_plugin_for_backup command should perform the activities necessary to initialize the remote storage system before backup begins. Set up activities may include creating remote directories, validating connectivity to the remote storage system, checking disks, and so forth.
- The absolute path to the plugin configuration YAML file.
- The local directory on the Greenplum Database host (master and segments) to which gpbackup will write backup files. gpbackup creates this local directory.
The setup_plugin_for_backup command must exit with a value of 0 on success, non-zero if an error occurs. In the case of a non-zero exit code, gpbackup displays the contents of stderr to the user.
