Best pratice : Add dedicated host for CR or DR.

[Dezerd]

Hello,

We have two hosts in a pool with 'classic' backups (Backup and delta).

I would like to mount a DR/CR plan by adding a third dedicated host of the first two in order to store the VMs ready to start.
His independence (but I may be mistaken) would allow him not to be subject to a failure of the master host.

How to add it in XOA without putting it in the same pool?

Basically, what are the best practices for this configuration?

Thank you,

@Dezerd Hi !

Just add the third host via New -> Server, it will appear as an independent host in his own pool (assuming the third host was just installed).

@Dezerd and you can either add the replication to the same backup job if you have a good connection between host, or create separate replication jobs

a replication is quite neat, especially for a fast restart, since the replicated VM is ready to start

[Dezerd]

Thank you.
So this host will have a separate network/storage partition since it will be in a dedicated pool?

Yes, the connection to this host should be quite good.

If I lose XOA on my master host, what is the procedure for start these replication VMs? From another XOA or Xo Lite? Once the incident is resolved, is it possible to merge the replication VM with the original VM?

@Dezerd you just have to start-copy the Replica VM

it permits the original job to keep replicating on the VM.
there is no failover/failback mecanism AFAIK

if you work on replica started VM, you will have to put up in place a replica going to original hosts
