> The backup logic scans the logs and oldlogs:
>  * IncrementalBackupManager#getLogFilesForNewBackup
>  * (Introduced in HBASE-29776) FullTableBackupClient#execute
> It assumes old logs are files under the "oldWals" folder.
> However, there's a configuration key hbase.separate.oldlogdir.by.regionserver that can change this behavior. When set to true, the old logs are stored in directories under "oldWals". The backup code will error on this.
