Remote storage for Tungsten Fabric database backups

MOSK enables you to store Tungsten Fabric database backups on a remote storage system. Using remote storage helps offload backups from the control plane nodes, improves data durability, and simplifies disaster recovery procedures. This section explains how to configure the supported remote storage options, including Network File System (NFS) storage and S3 object storage.

Remote NFS storage for Tungsten Fabric database backups

Available since MOSK 23.2 TechPreview

MOSK supports configuring a remote NFS storage for Tungsten Fabric data backups through the TFOperator custom resource:

spec:
  features:
     dbBackup:
       enabled: true
       backupType: "pv_nfs"
       nfsOptions:
         path: <PATH_TO_SHARE_FOLDER_ON_SERVER>
         server: <IP_ADDRESS/DNS_NAME_OF_SERVER>

spec:
  controllers:
    tf-dbBackup:
      enabled: true
      backupType: "pv_nfs"
      nfsOptions:
        path: <PATH_TO_SHARE_FOLDER_ON_SERVER>
        server: <IP_ADDRESS/DNS_NAME_OF_SERVER>

If PVC backups were used previously, the old PVC will not be utilized. You can delete it with the following command:

kubectl -n tf delete pvc <TF_DB_BACKUP_PVC>
