Restoring a Database from a Backup
If you have a database enabled for database rebalancing with the segment, legacy or bucket policy, the order of forests on the database may differ from the order of forests when the database was backed up. You can execute xdmp:database-restore-validate function to return a backup-plan containing a database element that shows the order of the forests when the backup was done. If the order of the forests do not match, then you should execute the admin:database-reorder-forests function to reorder the forests on your database before restoring it from the backup.
Note
When using the segment, legacy or bucket policy, if the order of forests on the database being restored differs from the order of forests when the database was backed up, the restore operation may trigger major data movement between the forests on the restored database.
