    Unspecified = 0,

}

Defines the behavior for handling the situation where sets of namespaced resources being restored already exist in the target cluster.

Variants

Unspecified = 0

Unspecified (invalid).

DeleteAndRestore = 1

When conflicting top-level resources (either Namespaces or ProtectedApplications, depending upon the scope) are encountered, this will first trigger a delete of the conflicting resource AND ALL OF ITS REFERENCED RESOURCES (e.g., all resources in the Namespace or all resources referenced by the ProtectedApplication) before restoring the resources from the Backup. This mode should only be used when you are intending to revert some portion of a cluster to an earlier state.

FailOnConflict = 2

If conflicting top-level resources (either Namespaces or ProtectedApplications, depending upon the scope) are encountered at the beginning of a restore process, the Restore will fail. If a conflict occurs during the restore process itself (e.g., because an out of band process creates conflicting resources), a conflict will be reported.

MergeSkipOnConflict = 3

This mode merges the backup and the target cluster and skips the conflicting resources. If a single resource to restore exists in the cluster before restoration, the resource will be skipped, otherwise it will be restored.

MergeReplaceVolumeOnConflict = 4

This mode merges the backup and the target cluster and skips the conflicting resources except volume data. If a PVC to restore already exists, this mode will restore/reconnect the volume without overwriting the PVC. It is similar to MERGE_SKIP_ON_CONFLICT except that it will apply the volume data policy for the conflicting PVCs:

• RESTORE_VOLUME_DATA_FROM_BACKUP: restore data only and respect the reclaim policy of the original PV;
• REUSE_VOLUME_HANDLE_FROM_BACKUP: reconnect and respect the reclaim policy of the original PV;
• NO_VOLUME_DATA_RESTORATION: new provision and respect the reclaim policy of the original PV. Note that this mode could cause data loss as the original PV can be retained or deleted depending on its reclaim policy.

MergeReplaceOnConflict = 5

This mode merges the backup and the target cluster and replaces the conflicting resources with the ones in the backup. If a single resource to restore exists in the cluster before restoration, the resource will be replaced with the one from the backup. To replace an existing resource, the first attempt is to update the resource to match the one from the backup; if the update fails, the second attempt is to delete the resource and restore it from the backup. Note that this mode could cause data loss as it replaces the existing resources in the target cluster, and the original PV can be retained or deleted depending on its reclaim policy.

Implementations

impl NamespacedResourceRestoreMode

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of NamespacedResourceRestoreMode.

pub fn from_i32(value: i32) -> Option<NamespacedResourceRestoreMode>

👎Deprecated: Use the TryFrom<i32> implementation instead

Converts an i32 to a NamespacedResourceRestoreMode, or None if value is not a valid variant.

impl NamespacedResourceRestoreMode

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.

Trait Implementations

impl Clone for NamespacedResourceRestoreMode

fn clone(&self) -> NamespacedResourceRestoreMode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NamespacedResourceRestoreMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for NamespacedResourceRestoreMode

fn default() -> NamespacedResourceRestoreMode

Returns the “default value” for a type.

impl From<NamespacedResourceRestoreMode> for i32

fn from(value: NamespacedResourceRestoreMode) -> i32

Converts to this type from the input type.

impl Hash for NamespacedResourceRestoreMode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for NamespacedResourceRestoreMode

fn cmp(&self, other: &NamespacedResourceRestoreMode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for NamespacedResourceRestoreMode

fn eq(&self, other: &NamespacedResourceRestoreMode) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for NamespacedResourceRestoreMode

fn partial_cmp(&self, other: &NamespacedResourceRestoreMode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<i32> for NamespacedResourceRestoreMode

type Error = UnknownEnumValue

The type returned in the event of a conversion error.

fn try_from( value: i32, ) -> Result<NamespacedResourceRestoreMode, UnknownEnumValue>

Performs the conversion.
