Hi KV Singh.

I would not recommend changing time on the Commserver due to below reasons.


  1. A few hours change in time will cause Commserver to detect the time change and will disable data aging.
  2. The Commserver will create a CA certificate based on the new time. This will cause backups to fail and communication issues due to certificate mismatch between Commserver and the clients.
  3. Schedules will go haywire due to change in time.
  4. Webconsole report will SLA and other report will report incorrectly.

If you have any questions or issue with retention, I suggest opening a case with Commvault support team and they will be happy to assist.
