Actually, I have scheduled regular backup in my Zimbra server. I got a problem while checking my Zimbra server backup using the command zmbackupquery. I got the following error upon running it. I am very sorry to ask if you feel if it is a silly question.

[zimbra@test ~]$ zmbackupquery
[] ERROR: java.security.cert.CertificateExpiredException: NotAfter: Tue Oct 17 10:06:32 EST 2006
Error occurred: java.security.cert.CertificateException: Untrusted Server Certificate Chain

Could anyone tell me why I got this error and what the steps I need to take to check the backup details using the command zmbackupquery?

Thanks in advance
