Known Issues

This release of Kubesafe software contains some known defects and limitations:

  1. The S3 storage target supports only one producer to one consumer. That is, you should only configure two clusters to a particular remote S3 target. A future release will remove this limitation.

  2. S3 backups are full rather than incremental. A future release will back up only changed data to S3.

  3. Remote protection policies do not respect the retention value. That is, snapshots created on the remote target remain indefinitely. You must remove snapshots when you no longer need them. A future release will prune remote snapshots automatically to keep only the specified number.

  4. If you back up an application that is not in a runnable condition, future clones or restores from that snapshot will also not be in a runnable condition.

  5. You can’t delete cluster or object store configurations once they have been uploaded to Kubesafe. A future release will add this capability.

  6. The cluster name (ks_cluster_id) you specify in configuration files must not contain any of these characters:

/. “$

  1. If you define an application as an individual Pod, Kubesafe cannot restore or clone the application on a remote cluster. Such configurations are unusual, as applications will normally use a Deployment, StatefulSet, or DaemonSet rather than defining a Pod directly.

  2. Kubesafe requires that all nodes in your cluster run in the same region and zone.

  3. Kubesafe currently supports only a single type of storage on clusters used for cloning or restoring applications. For example, a cluster used for cloning or restoring can use EBS storage or Gluster storage, but not both.
