What Types of Restores Does ON-Bar Perform

You can restore storage spaces stored in both raw and cooked files. If your system contains primary and mirror storage spaces, ON–Bar writes to both the primary and mirror chunks at the same time during the restore, except for an external restore. Mirroring is a strategy that pairs a primary chunk of one storage space with an equal-sized mirror chunk.

Important:
You cannot specify temporary dbspaces in a warm or cold restore. When you restore the critical dbspaces (for example, the root dbspace), the database server re-creates the temporary dbspaces, but they are empty.
