Backups with R1Soft

I’ve setup a host VPS which is based on KVM which is hosting a couple docker containers.

I’m trying to backup the host VPS but it keeps giving me errors about docker stuff, I’ve excluded /var/lib/docker but it’s still giving me errors. Am I missing something? I don’t need the docker containers backed up as the storage is located on the host VPS.

In case you missed the title, the backup software is R1Soft.

Thanks,

Mike
