I have a large container that I'd like to use vzdump to backup. I'm currently tar'ing the home directory separately so I want to use the exclude-path option so I don't backup the /home/ dir.

problem:
it creates a full instance/copy (includes all directories) and ignores the flag --exclude-path '/home/.+' (22gb directory) until it creates the tar.

is it possible to set vzdump to exclude the path when creating the copy of the container?

My problem is my container is larger than my free disk space

output of log file on my smaller VPS:
