Functions ¶
func NewVolumeHelperWithCache ¶
func NewVolumeHelperWithCache( backup velerov1api.Backup, client crclient.Client, logger logrus.FieldLogger, pvcPodCache *podvolumeutil.PVCPodCache, ) (vhutil.VolumeHelper, error)
NewVolumeHelperWithCache creates a VolumeHelper using an externally managed PVC-to-Pod cache. This is used by plugins that build the cache lazily per-namespace (following the pattern from PR #9226). The cache can be nil, in which case PVC-to-Pod lookups will fall back to direct API calls.
func NewVolumeHelperWithNamespaces ¶
func NewVolumeHelperWithNamespaces( volumePolicy *resourcepolicies.Policies, snapshotVolumes *bool, logger logrus.FieldLogger, client crclient.Client, defaultVolumesToFSBackup bool, backupExcludePVC bool, namespaces []string, ) (vhutil.VolumeHelper, error)
NewVolumeHelperWithNamespaces creates a VolumeHelper with a PVC-to-Pod cache for improved performance. The cache is built internally from the provided namespaces list. This avoids O(N*M) complexity when there are many PVCs and pods. See issue #9179 for details. Returns an error if cache building fails - callers should not proceed with backup in this case.
func ShouldPerformSnapshotWithBackup
deprecated
func ShouldPerformSnapshotWithBackup( unstructured runtime.Unstructured, groupResource schema.GroupResource, backup velerov1api.Backup, crClient crclient.Client, logger logrus.FieldLogger, ) (bool, error)
ShouldPerformSnapshotWithBackup is used for third-party plugins. It supports to check whether the PVC or PodVolume should be backed up on demand. On the other hand, the volumeHelperImpl assume there is a VolumeHelper instance initialized before calling the ShouldPerformXXX functions.
Deprecated: Use ShouldPerformSnapshotWithVolumeHelper instead for better performance. ShouldPerformSnapshotWithVolumeHelper allows passing a pre-created VolumeHelper with an internal PVC-to-Pod cache, which avoids O(N*M) complexity when there are many PVCs and pods. See issue #9179 for details.
func ShouldPerformSnapshotWithVolumeHelper ¶ added in v1.18.0
func ShouldPerformSnapshotWithVolumeHelper( unstructured runtime.Unstructured, groupResource schema.GroupResource, backup velerov1api.Backup, crClient crclient.Client, logger logrus.FieldLogger, vh vhutil.VolumeHelper, ) (bool, error)
ShouldPerformSnapshotWithVolumeHelper is like ShouldPerformSnapshotWithBackup but accepts an optional VolumeHelper. If vh is non-nil, it will be used directly, avoiding the overhead of creating a new VolumeHelper on each call. This is useful for BIA plugins that process multiple PVCs during a single backup and want to reuse the same VolumeHelper (with its internal cache) across calls.
