First, my network: the issue I will cover involves two LInux servers on our internal network. For discussion, Server A and Server B, 10.0.5.15 and .25 respectfully. Server A is hosting Dupliciti and Server B is a NginX/Postfix/Dovecot e-mail server.
I’m trying to use Dupliciti to backup the SQL folders/files and, for each of the e-mail domains, the /var/vmail folders/files . As indicated above, Dupliciti is running on a different server than the email. I have created “mount points” on the Dupliciti server which correctly point to each the e-mail SQL folder/files and the /var/vmail folders/files. From the Server A I can access and list folders and files using those “mount points”.
The Dupliciti backup for the SQL folders/files is working perfectly.
However for the /var/vmail backup job I get no content saved and 4 warnings, see below. Since it is working for the SQL folders/files, but not the /var/vmail folders and files, my first thought is that it is a permissions issue. But I do not know how to verify that nor how to correct it. Can someone assist?
