RecoverPoint SE - CG's initializing after power failure - risks?
Hello,
Our PRI site has many power issues, and we have experienced several 2-3 hour power outages this year (five of them). After the site recovers, all of the CG's which repl to our SEC site go into "initializing". Despite several requests to properly protect this site with either a generator, or colocate the VNX2 into a proper datacenter, I would like to present the risks of these numerous power outages.
* If a RP CG is initializing, what would happen if the power goes down again during this time? Would we loose the ability to failover?
* If a CG is initializing, does that mean we cannot failover should something else happen that might require a failover?
* Each power outage usually requires RP to initialize back up, and will take around 3-4 days before everything is "green" and working properly again - what risk do we have during initialization of the CG's?
* We have CG's from our SEC site to our PRI site as we have a small infrastructure serving up VM's in that location, and those CG's remain "green".

Thank you for the response. So, our RPO could go as high as the time it takes for everything to re-init?
Also, how could I confirm if there is a snapshot in the repl copy journal?
Thank you very much for your help,
Bruce

* You never lose the ability to failover as long as there are snapshots in the replica copy journal
* Ditto above
* The risk is RPO exposure and the potential for a long resync state whereby the accumulated data is larger than the size of the replica copy jurnal and therefore no PiT snapshots exist
