Subject [jira] [Commented] (HBASE-19105) Add ability to compare backups in HBase backups.
Date Wed, 01 Nov 2017 20:43:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-19105?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16234718#comment-16234718

Vladimir Rodionov commented on HBASE-19105:
-------------------------------------------

That is not that easy and straightforward. 

First of all, it is not possible to execute two *identical* backups on different clusters
- they will always be slightly different due to the replication lag, for example. In a primary
+ DR configuration, I would suggest doing backups *only* in DR cluster. In this case you will
always have single source of backed up data.

What do you think, [~amitkabraiiit]?

> For certain scenarios eg DR scenario, before making a site switch we need to ensure that
backups in primary and dr is same. Tool to compare the backups helps in such case that can
do cross cluster backups validation.
>  
> Current backups generate data in backup_<timestamp> format and this can be different
in primary and dr and is not easily comparable.
