Plugin command to clean up a storage plugin after restore.
<plugin_executable> cleanup_plugin_for_restore <plugin_config_file> <local_backup_dir> <scope>
<plugin_executable> cleanup_plugin_for_restore <plugin_config_file> <local_backup_dir> <scope> <contentID>
gprestore invokes the
cleanup_plugin_for_restore plugin command when a
gprestore operation completes, both in success and failure cases. The scope argument specifies the execution scope.
gprestore will invoke the command with each of the scope values.
cleanup_plugin_for_restore implementation should perform the actions necessary to clean up the remote storage system after a restore. Clean up activities may include removing remote directories or temporary files created during the restore, disconnecting from the backup service, etc.
The local directory on the Greenplum Database host (master and segments) from which
gprestore reads backup files.
master, the local_backup_dir is the backup directory of the Greenplum Database master.
segment, the local_backup_dir is the backup directory of a segment instance. The contentID identifies the segment instance.
segment_host, the local_backup_dir is an arbitrary backup directory on the host.
The execution scope value indicates the host and number of times the plugin command is executed. scope can be one of these values:
master- Execute the plugin command once on the master host.
segment_host- Execute the plugin command once on each of the segment hosts.
segment- Execute the plugin command once for each active segment instance on the host running the segment instance. The contentID identifies the segment instance.
The contentID of the Greenplum Database master or segment instance corresponding to the scope. contentID is passed only when the scope is
master, the contentID is
segment, the contentID is the content identifier of an active segment instance.
cleanup_plugin_for_restore 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,
gprestore displays the contents of
stderr to the user.
