Subject [jira] [Commented] (HBASE-19106) Backup self validation for its correctness.
Date Mon, 30 Oct 2017 23:11:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-19106?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16225942#comment-16225942

Ted Yu commented on HBASE-19106:

The amount of data in the source tables may be big.
Where should the validation job restore to ?

Considering that restore job may take non-trivial duration, how should the result of restore
be delivered ?

> Backups are critical and if they don't work when we need them at the time of restore
than they are not useful. We should do sanity test for each backup job we run that it is restorable
and hence can be trusted.
> A self validation feature can be added for the same to the backups where whenever a backup
is run , once it finishes it will trigger a validation job that will do a sample restoration
of the backed up data and will make sure that it compares well with actual data.
