How to take OCR backup on

How to take OCR backup on

1. Overview

11g Release 2 on wards voting disk data is automatically backed up in the OCR whenever there is a configuration change.
No need to take voting disk backup separately, OCR backup will contain both OCR and Voting data. We can restore voting disk using OCR backup.


Automatic backups :

a) CRSD automatically creates OCR backups every 4 hours.
b) Each full day.
c) End of each week.
d) Retains the last three copies of OCR.

Manual backups:

a) can be taken using the "ocrconfig -manualbackup" command
