Question Exclude a subdomain from a backup?

[Paul Larson]

I'm having trouble excluding a subdomain from a domain backup.

I want to exclude:

/var/www/vhosts/mydomain.com/subdomain.org

If I can only specify directories relative to the website, I know how to exclude:

/var/www/vhots/mydomain.com/httpdocs/some-directory..

But for the subdomain, ../subdomain.org didn't seem to work!
