Failback after permanent failover?

[t_ahrens]

Hello all,

Another question concerning VM replicas...

Is it possible to failback to original productive VM after having commited "permanent failover", or only if the replica is in "failover" state?

Or asked the other way round: what is the difference between "failover" and "permanent failover" respectively, what is the special use / what are the advantages of these both failover options?

After reading the documentation, the difference / use has not become clear to me. In which case do I have to use which option?

Regards

Hello Thorger,

You can treat failover as a temporary process that should be finalized.
You have three options for finalizing:
1. Undo failover - discard all changes being made in temporary\replica VM during it's up time and get back to original VM.
2. Failback - preserve all changes being made in temporary\replica VM and get back to original VM merging them into it.
3. Permanent failover - the original VM will never come back due to a disaster, so merge all changes into temporary\replica VM and recognize it as production, without ability to undo or failback lately.

Hope that answered your questions. Thanks!

Hi Thorger

In reference to "merge all changes into temporary\replica VM and recognize it as production," is there a process to do this or does the veean permanent failover process take care of the merges. thanks

Hi John,

During the permanent failover the merge process is fully managed by Veeam, I hope that answered your question. Thanks!
