The --no-perms option ensures that no attempt is made to transfer permissions, which can fail if remote directories are not owned by the user that the container runs as. only sends files that are different between the source and the destination. One of the properties of container images is that they are immutable. Kubernetes provides an API to separate storage from computation, i.e., a pod can perform computations while the files in use are stored on a separate resource. Storage is provisioned by your cluster administrator by creating PersistentVolume objects from sources such as GCE Persistent Disk, AWS Elastic Block Store (EBS), and NFS mounts. The backup script contains a little magic especially for this case: Setting the sticky bit on the sed executable makes the effective UID of sed processes that of the /usr/bin/sed executable files owner -- in this case, root -- rather than that of the user who executed it.
