About Greenplum database backups
You can use the NetBackup interfaces to start Greenplum backups. You can also issue backup commands directly from the gpbackup utility to perform Greenplum backups.
The following types of backups are supported for Greenplum:
Full backups. This type of backup copies the entire database.
Incremental backups. This type of backup contains the database changes made since the last database backup. No schedule type is available for incremental backups. Instead, you must update the backup script to enable incremental backups. Also note that you must run a full backup before you run an incremental backup.
The most convenient way to back up your database is to set up schedules for automatic backups. When the NetBackup scheduler invokes a schedule for an automatic backup, the Greenplum backup scripts are run in the same order as they appear in the file list. The scheduler tries to find each script, and it runs the scripts that it finds. Information is available on how to initiate a manual backup or a user-directed backup of a policy.
