Cold-Restore Sequence on Dynamic Server

Figure 17 describes the ON–Bar cold-restore sequence. ON–Bar uses the backup emergency boot file to determine what restores are required.

In a cold restore, ON–Bar performs the following steps in order:

• Salvages the logical logs
• Restores the root dbspace
• Restores the critical dbspaces
• Restores blobspaces
• Restores noncritical dbspaces and sbspaces
• Restores logical logs

For each storage space, ON–Bar restores the last level-0 backup, the level-1 backup (if it exists), and the level-2 backup (if it exists). Finally, ON–Bar restores the logical logs.
