Description

The setup_plugin_for_restore command should perform the activities necessary to initialize the remote storage system before a restore operation begins. Set up activities may include creating remote directories, validating connectivity to the remote storage system, etc.

Arguments

plugin_config_file
The absolute path to the plugin configuration YAML file.
local_backup_dir
The local directory on the Greenplum Database host (master and segments) from which gprestore reads backup files. gprestore creates this local directory.
scope
The execution scope (host and number of times the plugin is executed) for the plugin.
  • master - Execute the plugin once on the master host.
  • segment_host - Execute the plugin once on each of the segment hosts.
  • segment - Execute the plugin once for each active segment instance on the host running the segment instance.
The Greenplum Database hosts and segment instances are based on the Greenplum Database configuration when the back up was first initiated.
