I have urbackup server web running via https now. I could not see an example on any web sites so I combined information from several places.
First I needed an “a2enmod proxy_fcgi” (which also brought in proxy) then I created and enabled a urbackup.conf file as below:
# UrBackup configuration file for apache 2.4 or later
<IfModule mod_alias.c>
Alias /urbackup /usr/share/urbackup/www
</IfModule>
<Directory "/usr/share/urbackup/www">
<IfModule mod_authz_host.c>
Require local
# Require ip 172.16.0.0/24 (replace this comment line for your network)
</IfModule>
</Directory>
<IfModule mod_proxy_fcgi.c>
ProxyPass "/urbackup/x" "fcgi://127.0.0.1:55413"
</IfModule>
After a restart on apache2 https://mysite.example/urbackup worked.
Please feel free to use this as you wish. Comments on how to improve the conf are welcome.
