<br>
You are right. The FQDN was the culprit. Once I entered the FQDN
in /etc/hosts file, the problem got resolved.<br>

Thanks for your guidance.<br>
<br>
By the way any document that explains what is
--restore-permissions in engine-backup process?<br>
<p>-- </p>

It is highly likely 1 of 2 things:<br>
<br>
1. The entropy mentioned by Brett, however that is mostly
applicable on hosted<br>
engine as VMs don't usually have good entropy.<br>
2. The engine cannot resolve itself (which looking at your
description is the<br>
likely culprit). Since you don't have DNS, you need to add the
fqdn to<br>
/etc/hosts so it can resolve itself.<br>
