AppBackup And AppRestore
AppBackup and AppRestore are project-level wrappers around Velero Backup and Restore. They normalize labels, source information, restore policies, status, and history.
AppBackup
AppBackup describes what should be backed up from a source cluster. It can be created manually or by DataSync and ResourceSync.
AppRestore
AppRestore describes how a backup should be restored to a target cluster. It may include restore policy, namespace mapping, resource selection, and modifiers.
Why Wrap Velero
Wrapping Velero resources lets the project expose stable APIs, application-level history, and consistent status even when multiple Velero resources are involved.
