Hi, i have more lxc container that work, i backup it and if i restore in other server or in with other id not work, i think for permission problem, it's a bug?
in vm some service not start for permission and other many error, for example:
install debian 8 and install mysql - work
backup
restore to another node or another proxmox server
mysql not start and give me socket error
but it's only an example
Yes, if you are running an uptodate proxmox installation this is enough to include /var/log and the other excluded-by-default files. Of course it will only affect future backups!
