Which Administrative Files to Back Up?

ON–Bar backups safeguard your data. They do not replace normal operating- system backups of important configuration files.

Important:

For use in an emergency, you should have a backup copy of the current version of the following administrative files. You will need to restore these files if you need to replace disks or if you restore to a second computer system (imported restore).

The following table lists the administrative files that you should back up.

Administrative Files	IDS	XPS
ONCONFIG file	X	X
Emergency boot files	X	X
sm_versions file	X	X
The sqlhosts file (UNIX)	X	X
The oncfg_servername.servernum file in the etc subdirectory	X
The oncfg_servername.servernum.coserverid file from each coserver		X
Storage-manager configuration and data files	X	X
Simple-large-object data in blobspaces that are stored on disks or optical platters	X
The xcfg_servername.servernum file in the etc subdirectory		X
Externally stored data such as external tables that a DataBlade maintains	X

Although ON–Bar does not back up the following items, ON–Bar automatically re-creates them during a restore. You do not need to make backup copies of these files:

The dbspace pages that are allocated to the database server but that are not yet allocated to a tblspace extent
Mirror chunks, if the corresponding primary chunks are accessible
Temporary dbspaces
ON–Bar does not back up or restore the data in temporary dbspaces. Upon restore, the database server re-creates empty temporary dbspaces.
