Only users with nocadm priviledges can perform backup and restore.
Only one instance of the EDIT window can be active at one time; other
instances of the EDIT window can be in VIEW mode only.
Backup & Restore
Database backup is performed for each controller to record and save the
contents of the database in a separate directory other than that of the controller.
Database restore is performed if a database of a controller becomes corrupted,
to replace the corrupted database with a known good backup database to
enable the controller to resume correct operation.
Backups are typically created at either of two times:
• recurring —daily, weekly, or other specified period
• one time — after significant changes have been made to the database or to
the controller environment
The backup directory can include up to nine separate backups.
A restore operation replaces the current contents of a controller database with
the contents of the selected backup file.
The primary reasons for restoring a database are
• the current database has been corrupted
• a recent update has introduced problems and a previous version must be
reactivated
• new hardware has been installed that requires a database
Multiple different backups are maintained for the following reasons:
• if one backup has been corrupted, another backup can be selected instead
• each backup is related to a specific time, configuration, and set of
parameters
