                               --source-server

                               [--no-wait]
                               [--storage-class-backups]
                               [--storage-class-data]
                               [--storage-class-logs]
                               [--time]
                               [--use-k8s]
                               [--volume-size-backups]
                               [--volume-size-data]
                               [--volume-size-logs]. The 1th example of the child command would be to use it to 'restore an azure arc enabled postgresql server', the syntax is: az postgres server-arc restore -n <to-pg> --source-server <from-pg> --k8s-namespace namespace --use-k8s. The parameter '--k8s-namespace -k' is required. It is used to the kubernetes namespace that contains the azure arc enabled postgresql. if no namespace is specified, then the namespace defined in the kubeconfig will be used.. The parameter '--name -n' is required. It is used to name of the azure arc enabled postgresql server to be created.. The parameter '--source-server' is required. It is used to the name of the azure arc enabled postgresql server to restore from.. The parameter '--dry-run' is optional. if set, validates the source and destination resources and the time, without performing the restore. the earliest and latest possible restore times are returned in the status of the restore task.. The parameter '--no-wait' is optional. do not wait for deployment to be ready before returning.. The parameter '--storage-class-backups' is optional. the storage class to be used for backup persistent volumes.. The parameter '--storage-class-data' is optional. the storage class to be used for data persistent volumes.. The parameter '--storage-class-logs' is optional. the storage class to be used for logs persistent volumes.. The parameter '--time -t' is optional. the point in time of the source server that will be restored to create the new azure arc enabled postgresql server. must be greater than or equal to the source database's earliest restore date/time value. time should be in following format: 'yyyy-mm-ddthh:mm:ssz'. if no time is provided, the most recent backup will be restored.. The parameter '--use-k8s' is optional. use local kubernetes apis to perform this action.. The parameter '--volume-size-backups' is optional. the size of the storage volume to be used for backups as a positive number followed by ki (kilobytes), mi (megabytes), or gi (gigabytes).. The parameter '--volume-size-data' is optional. the size of the storage volume to be used for data as a positive number followed by ki (kilobytes), mi (megabytes), or gi (gigabytes).. The parameter '--volume-size-logs' is optional. the size of the storage volume to be used for logs as a positive number followed by ki (kilobytes), mi (megabytes), or gi (gigabytes)..
