To automate the restore if the volumes we need to automate the following parts:

  • restore the backup without any PVs or PVCs

  • make sure to not create any PVs or PVCs automaticall (e.g. by Helm or Argo) -> therefore all pods stay in Pending state waiting for their PVCs.

  • Restore Backup in Longhorn klickibunti (NOT Disaster Recovery Volumes, thats for hot standby)

  • Restore the PVCs and PVs from within Longhorn -> Pods start automatically and attach the correct Volumes
