Protection Domains and Recovery in a disaster | Nutanix Community

Thoughts I'd post this rather than bugging our SE over and over ;)



Trying to get a disaster recovery plan in place to protect against a major disaster such as server room fire...



We have a couple of clusters geographically separated which I have set up as remote-sites. Site A and B lets call them.



I've set up a PD w/ consistency group with the VMs to protect and periodically snapshot from site A to B. Now in the case of a fire/destroyed cluster at site A... obviously step one is rebuilding a cluster at that site with the appropriate configs, but then...



With a brand new cluster in place, what is the standard process to retreive the snapshots from site B back to the new site A ?



So far, I've activated the backup on site B (as if it was an unplanned outage and left it off). and recreated the remote-site link on the newly built out site A. I am thinking I now create a new PD to shuffle the VMs/consistency group back to Site A and then activate there and I am done ?



I know this works as I've done it now. But is this the 'preferred method'?



I'd appreciate any thoughts from the gurus out there ;)



thanks, Brent
- hrmm, I dont think I understand the prompt there.



If you had 2 clusters, A and B, and you migrated a PD from A to B, and cluster A still existed, then by definition the PD would "be there" with some seed data, allowing you to re-replicate and fail back much easier.



In the case where cluster A "went away", then you can't really pre-build anything.







That said, If I missed the mark on understanding this, feel free to restate and I'll take a second swing.



Cheers,

Could you pre-build the failback PD? No scheduled replications etc. but then after you migrate to the failover location it might allow expedite of the failback?
ha! perfect thanks for the pointer, I completely missed that
(Standard Disclaimer) if this were to happen in real life, always make a support ticket before doing anything, and we'll help point you in the right direction.
Basically you remake the PD with the same name, and that will allow you to pull the PD/snaps back
