3 - Synchronization objects
Introduction
Astronetes offers the following synchronization objects to cover the infrastructure resiliency requirements.
Synchronization
Synchronizes the content of an asset to another one once. The operations required to perform the snapshot depend on the plugin. More information can be found in the Plugin section. Synchronizations are managed through the Synchronization Custom Resource Definition.
Synchronization Plan
Periodic snapshots with intervals set by the user. Periodicy is established as a cron expression. When the Synchronization Plan starts a new snapshot, it creates a new Synchronization resource akin to how a Kubernetes CronJob deploys a new Job whenever the cron expression indicates. Synchronization Plans are managed through the SynchronizationPlan Custom Resource Definition.
