backupstore: If the backup has the parameter backupmodea: full, it will pretend there is no last backup, and backup all the blocks of the current volume.

longhorn-manager:

RecurringJob app

• Add a new field .Spec.Parameters
• Get recurringJob.Status.ExecutionCount, +1 , then update it backup to the status
• if the parameter["full-backup-interval"] = N
  • "0": always incremental
  • "1": always full
  • "N": every N
• Create the Backup through API and pass the parameter to the Backup if job.executionCount%interval == 0
  • parameters: {"backup-mode": "full"}

Backup

• Add a new field .Spec.Parameters
• Add .Status.NewlyUploadedDataSize and .Status.ReUploadedDataSize to each Backup. So user can know the data transfer size for each Backup to trace the cost.
• pass the parameter to the snapshotBackup (improxy -> replica) to do the full backup

Webhook

• For Backup, validate the Backup.Spec.Parameters: only support "backup-mode: full/incremental"
• For RecurringJob, validate the RecurringJob.Spec.Parameters: only support "full-backup-interval: N"

CRD

• Add .Spec.Parameters to RecurringJob
• Add .Status.BackupCount to BackupVolume.
• Add .Status.NewlyUploadedDataSize and .Status.ReUploadedDataSize to Backup
