I can confirm this bug.
All my lxc backups exculdes /var/log.
It happens on a node with zfsvols storage and a node with the default local lvm storage too
I tried to put "stdexcludes: 0" in vzdump.conf, but not helped.

If I run vzdump manually in the console with "-stdexcludes 0" parameter, then the log directories are saved succesfully.
I found in the vzdump manual that the default value of the stdexcludes parameter is 1. I think it is wrong, it should be 0.
For some reason the "stdexcludes: 0" in vzdump.conf is ignored.
So I think Proxmox should append "-stdexcludes 0" to the parameters of vzdump to save lxc containers with the /var/log directories.

This was already reported as bug #926 and is fixed in pve-manager >= 4.1-24. As a workaround until that version is available in pve-nosubscription/pve-enterprise you can edit cron jobs / command line parameters to include "-stdexcludes 0".
