> Key: HBASE-30526
> URL: https://issues.apache.org/jira/browse/HBASE-30526
> Project: HBase
> Issue Type: Improvement
> Components: backup&restore
> Affects Versions: 4.0.0-alpha-1
> Reporter: Kevin Geiszler
> Assignee: Kevin Geiszler
> Priority: Major

> HBASE-30517 was created to resolve an issue where
> CustomBackupLocationPitrRestoreHandler.getBackupMetadata() was not filtering
> out non-COMPLETE backups. After further investigation, the only current
> solution involves using the BackupSystemTable to get each backup's state and
> determine whether is is complete. However, this is not an idea approach as
> it creates a dependency on the BackupSystemTable for backups with a
> CustomBackupLocation.
> Imagine a scenario where Cluster A creates one or more backups that are sent
> to an external storage location. Then, Cluster B want to perform a restore
> using one of these backups. If Cluster B's BackupSystemTable looks different
> than Cluster A's, then some tables may be left out of the PitrBackupMetadata.
> Instead, we should make is to COMPLETE backups have a .backup.complete marker
> file within the filesystem. Then,
> CustomBackupLocationPitrRestoreHandler.getBackupMetadata() can use this file
> to filter out non-COMPLETE backups.
