In your blog, while installing Wordpress you have selected LAMP and in one of the comments, you told that using webmin will take RAM and CPU high. I have a vps server from contabo and my spec is 4 vCores, 8 GB RAM & 200 GB SSD
a) is this a good spec to use webmin without any issues? will it create any problem when I host a single or 2 sites? I mean can this spec handle the webmin usage without affecting other areas?
b) I am confused about taking backup. what backup should I take, server backup separately or backup using Webmin feature or backup using Wordpress backup plugin . please help
a) yes you can use webmin without any issues.
b) Take a backup using Wordpress plugins.
