[jira] [Created] (HBASE-28449) Fix BackupSystemTable Scans

Briana Augenreich created HBASE-28449:
-----------------------------------------

             Summary: Fix BackupSystemTable Scans 
                 Key: HBASE-28449
                 URL: https://issues.apache.org/jira/browse/HBASE-28449
             Project: HBase
          Issue Type: Bug
            Reporter: Briana Augenreich


When calculating which WALs should be included in an incremental backup the backup system does a prefix scan for the last roll log timestamp. This uses the backup root in the prefix (<prefix><backupRoot>.) If you happen have multiple backup roots where one is a root of the other you'll get inaccurate results. 

 

Since the rowkey is <prefix><backupRoot><null separator><server> let's modify the prefix scan to be <prefix><backupRoot><null separator>.
