Vinayak Hegde updated HBASE-28990:
----------------------------------
Description:
The incremental backup collects all the WALs generated since the last full or
incremental backup and processes them into HFiles for optimized restoration.
With the new continuous backup feature, the necessary WALs are already
available at the backup location and are used directly, eliminating the need to
retrieve them from the source cluster.
The incremental backup command itself remains unchanged.
If previous backups are part of a continuous backup: Uses the WALs already
backed up in the backup location.
If previous backups are not part of a continuous backup: Operates as a
traditional incremental backup, collecting WALs from the source cluster.
> Modify the "Incremental" Command to Leverage Existing Backed-Up WALs for
> Continuous Backup
