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>.
