The Restore
API type is used as a request for the Velero server to perform a Restore. Once created, the
Velero Server immediately starts the Restore process.
Restore belongs to the API group version velero.io/v1
.
Here is a sample Restore
object with each of the fields documented:
# Standard Kubernetes API Version declaration. Required.
apiVersion: velero.io/v1
# Standard Kubernetes Kind declaration. Required.
kind: Restore
# Standard Kubernetes metadata. Required.
metadata:
# Restore name. May be any valid Kubernetes object name. Required.
name: a-very-special-backup-0000111122223333
# Restore namespace. Must be the namespace of the Velero server. Required.
namespace: velero
# Parameters about the restore. Required.
spec:
# The unique name of the Velero backup to restore from.
backupName: a-very-special-backup
# The unique name of the Velero schedule
# to restore from. If specified, and BackupName is empty, Velero will
# restore from the most recent successful backup created from this schedule.
scheduleName: my-scheduled-backup-name
# ItemOperationTimeout specifies the time used to wait for
# asynchronous BackupItemAction operations
# The default value is 4 hour.
itemOperationTimeout: 4h
# UploaderConfig specifies the configuration for the restore.
uploaderConfig:
# WriteSparseFiles is a flag to indicate whether write files sparsely or not
writeSparseFiles: true
# ParallelFilesDownload is the concurrency number setting for restore
parallelFilesDownload: 10
# Array of namespaces to include in the restore. If unspecified, all namespaces are included.
# Optional.
includedNamespaces:
- '*'
# Array of namespaces to exclude from the restore. Optional.
excludedNamespaces:
- some-namespace
# Array of resources to include in the restore. Resources may be shortcuts (for example 'po' for 'pods')
# or fully-qualified. If unspecified, all resources are included. Optional.
includedResources:
- '*'
# Array of resources to exclude from the restore. Resources may be shortcuts (for example 'po' for 'pods')
# or fully-qualified. Optional.
excludedResources:
- storageclasses.storage.k8s.io
# restoreStatus selects resources to restore not only the specification, but
# the status of the manifest. This is specially useful for CRDs that maintain
# external references. By default, it excludes all resources.
restoreStatus:
# Array of resources to include in the restore status. Just like above,
# resources may be shortcuts (for example 'po' for 'pods') or fully-qualified.
# If unspecified, no resources are included. Optional.
includedResources:

# Array of resources to exclude from the restore status. Resources may be
# shortcuts (for example 'po' for 'pods') or fully-qualified.
# If unspecified, all resources are excluded. Optional.
excludedResources: []
# Whether or not to include cluster-scoped resources. Valid values are true, false, and
# null/unset. If true, all cluster-scoped resources are included (subject to included/excluded
# resources and the label selector). If false, no cluster-scoped resources are included. If unset,
# all cluster-scoped resources are included if and only if all namespaces are included and there are
# no excluded namespaces. Otherwise, if there is at least one namespace specified in either
# includedNamespaces or excludedNamespaces, then the only cluster-scoped resources that are backed
# up are those associated with namespace-scoped resources included in the restore. For example, if a
# PersistentVolumeClaim is included in the restore, its associated PersistentVolume (which is
# cluster-scoped) would also be backed up.
includeClusterResources: null
# Individual objects must match this label selector to be included in the restore. Optional.
labelSelector:
matchLabels:
app: velero
component: server
# Individual object when matched with any of the label selector specified in the set are to be included in the restore. Optional.
# orLabelSelectors as well as labelSelector cannot co-exist, only one of them can be specified in the restore request
orLabelSelectors:
- matchLabels:
app: velero
- matchLabels:
app: data-protection
# namespaceMapping is a map of source namespace names to
# target namespace names to restore into. Any source namespaces not
# included in the map will be restored into namespaces of the same name.

# restorePVs specifies whether to restore all included PVs
# from snapshot. Optional
restorePVs: true
# preserveNodePorts specifies whether to restore old nodePorts from backup,
# so that the exposed port numbers on the node will remain the same after restore. Optional
preserveNodePorts: true
# existingResourcePolicy specifies the restore behaviour
# for the Kubernetes resource to be restored. Optional
existingResourcePolicy: none
# ResourceModifier specifies the reference to JSON resource patches
# that should be applied to resources before restoration. Optional

# Actions to perform during or post restore. The only hooks currently supported are

# How long to wait for a container to become ready. This should be long enough for the
# container to start plus any preceding hooks in the same container to complete. The wait
# timeout begins when the container is restored and may require time for the image to pull
# and volumes to mount. If not set the restore will wait indefinitely. Optional.
waitTimeout: 5m
# How long to wait once execution begins. Defaults to 30 seconds. Optional.
execTimeout: 1m
# How to handle execution failures. Valid values are `Fail` and `Continue`. Defaults to
# `Continue`. With `Continue` mode, execution failures are logged only. With `Fail` mode,
# no more restore hooks will be executed in any container in any pod and the status of the
# Restore will be `PartiallyFailed`. Optional.
