======Overview======

Backup of the OCR can be done by either:

  - Manual Backup
  - Export

====Manual Backup====
The manual backup can be performed via the following command:

<sxh bash>
[root@lparaca install]# ocrconfig -manualbackup

lparaca     2018/01/23 03:51:00     +DATA:/lparac-scan/OCRBACKUP/backup_20180123_035100.ocr.297.966138661     0

lparaca     2018/01/21 14:01:51     +DATA:/lparac-scan/OCRBACKUP/backup_20180121_140151.ocr.291.966002513     0
[root@lparaca install]#
</sxh>

The status/list of all backups can be displayed as follows:

<sxh bash>
[root@lparaca install]# ocrconfig -showbackup

</sxh>


====Export====
The export, exports only the metadata, but cannot recreate them. Exports should be done before any major change, such as adding / removing of a node.

<sxh bash>
[root@lparaca install]# ocrconfig -export /tmp/ocr.exp
PROT-58: successfully exported the Oracle Cluster Registry contents to file '/tmp/ocr.exp'



</sxh>
Usually, backup are done automatically by the GridInfra itself, however is never bad to perform your own.
