> Log filtering in IncrementalBackupManager can lead to data loss
> ---------------------------------------------------------------
>
> Key: HBASE-29776
> URL: https://issues.apache.org/jira/browse/HBASE-29776
> Project: HBase
> Issue Type: Improvement
> Components: backup&restore
> Reporter: Hernan Romer
> Priority: Major
> Labels: pull-request-available
>
> At the moment, incremental backups will filter out old wals that belong to RS
> which do not have any active WAL files.
>
> The code
>
> {code:java}
> // It is possible that a host in .oldlogs is an obsolete region server
> // so newestTimestamps.get(host) here can be null.
> // Even if these logs belong to a obsolete region server, we still need
> // to include they to avoid loss of edits for backup.
> Long newTimestamp = newestTimestamps.get(host);
> if (newTimestamp == null || currentLogTS > newTimestamp) {
> newestLogs.add(currentLogFile);
> }{code}
> Is doing the opposite of what the comment (correctly) says.
