Automatic OCR backups

Oracle CRS backs up the OCR automatically at regular intervals.

The standard backup frequency and retention policies are

  • Every 4 hours – keeping the last 3 copies.
  • Every day (at the end) – keeping the last 2 copies.
  • Every week (at the end) – keeping the last 2 copies.


You can find the location of the backup as well as which node carries out the backup (only one node backs up the OCR) with the following command:

ocrconfig -showbackup auto

The files may not all be on the node that caries out the backups because of outages.
