    <trans>If you restore from Koozali SME Server 9 or before, pay attention that some folders in the system are now symlinks. Basic backup configuration does not include /bin, /lib, /lib64, /sbin, /var/lock and /var/run. If you have added them for files in their subdirectories, we will prevent the restoration of those folders to prevent dar from replacing those symlinks and leave the system unusable. Those additions are, however, not recommended as they are at risk to overwrite files provides by rpms.</trans>
