Thanks for the fast reply. Maybe I try to explain a little more:
We have a 2 host cluster with vSphere 6.0 onsite where also the physical backupserver is located. All is connected via 10 Gb Ethernet and we use transportmode san for the backups. Additional there is a third host offsite in another building connected over a 1Gb connection. The vCenter is a virtual maschine which is located within the cluster on one of the two hosts.
We configured a normal backup job to backup all machines which are part of the cluster. That runs very good without any problems.
After that we wanted to replicate some maschines to the other building. That works very good too, if we don´t replicate the vcenter. (I will try to replicate from backup, that seems to be a very goog suggestion. Thank you @kawiMTF)
We had it two times (as we tried to replicate the vCetner) that in that moment the replication job starts (a vmware snapshot created) the eventlog from the live VM lists an error something like that: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2006849
The job has already replicated the vcenter but some other maschine in the job are sill running. Then the vcenter service crashes ( maybe a result from creating snapshot) and the replication job fails. I cannot start the vcenter service anymore. I need to restore the whole machine. But I can´t use the replicated maschine, because the failure is there already also present. I need to go back 1 restorepoint from my backup which runs without problems.
Now the question: Is it possible to replicate every kind of maschine regardless if it is an SQL DB or the vcenter or something else without getting the data currupted or is that not the recommended way?
