Dear Community,

 

I'm thinking out loud and any suggestions are welcome

I have 2 sites, 1 commserve on each site with livesync enabled and replication is each 15mn

ONPREM SITE 1 

2 MA with dedup + Storage

ONPREM SITE 2

2 MA with dedup + storage

 

on AWS, we have one S3 bucket receving third copy from ONPREM SITE 1

Question, in case of DR, wirth both site done, I want to rebuild from scratch

 

is this a viable scenario ?


We have only the dump of the commserve from Metallic

 

  1.  Build a Commseve
  2. Load the COmmserve DB dump
  3. Build a new access node
  4. Attach the access node to the S3 bucket
  5. Add new VMware hypervisor 
  6. Start restore from S3 bucket 3rd copy to the new VMware on Cloud environnement (like EVS etc...)


I have doubts on these steps :)
 

3 - Build a new access node

4 - Attach the access node to the S3 bucket

 

Thanks to all for your help !!

Oof. I hope you’re not bound to tight RPO / RTOs.

You could potentially stage a new CommServe and MediaAgent into your VMC on AWS environment, and use it develop the required network configurations, firewall rules, service accounts, etc.

It’s not as good as real-life testing, but at least you would have a process to follow.

It would work, but my concern with your approach is that in a Disaster Recovery scenario, can you really afford to be spending that much time trying to bring Commvault back online?

If feasible, I would highly recommend having your Standby CommServe and MediaAgent / Access Node in place and tested.

Hi ​@Erase4ndReuseMedia thanks, I've suggested they get a second commserve DR on the third site, and use log shipping, but Cyber team don't want any communication between the third site and the ON Prem Sites .... they wanted to have a completed isolated env, no licesync to the third site :(
