Ray Mattingly commented on HBASE-28084:
---------------------------------------
I agree with your thoughts here [~dieterdp_ng] . I'd appreciate your input on
https://issues.apache.org/jira/browse/HBASE-28697 , a similar issue, and
whether we should just require full backups after any incremental failures.
> Incremental backups should be forbidden after deleting backups

> Key: HBASE-28084
> URL: https://issues.apache.org/jira/browse/HBASE-28084
> Project: HBase
> Issue Type: Bug
> Components: backup&restore
> Reporter: Dieter De Paepe
> Priority: Major
>
> Imagine I have a set of backups (Full1, Incr2, Incr3), delete the last backup
> (Incr3), and then create a new incremental backup (Incr4).
> This backup history will now show: Full1, Incr2, Incr4.
> However, restoring Incr4 will not contain the data that was captured in
> Incr3, effectively leading to data loss. This will certainly surprise some
> users.
> I suggest to add some internal bookkeeping to prevent incremental backups in
> case the most recent backup was deleted.
