Offsite replication for DR scnario


We want to switch to Veeam from Arcserve to see if it is better for DR scenario.  Arcserve is good product and does everything what we needed until we switched to SDWAN solution. We used to have primary backup console at production site and remote replication server at DR site. When switched to SDWAN primary server can not replicate backup to remote server (even though nothing blocked). So we have to moved replication server to the production site leaving backup repository at DR site. As a alternate solution, I copy replication server’s C: drive to DR site. If we have replication server at DR site, I can create virtual standby of VM to DR site every night. So in case of disaster this will reduce restore time. We also want to test DR solution every six month.

I want to know does Veeam provide similar or better functionality in term of restore VM on DR site without relying on production VBR server?

Thanks

You will want to check out the user guide for replication but there are different scenarios.  See here - https://helpcenter.veeam.com/docs/backup/vsphere/replication_components.html?ver=120

Also Veeam also has CDP - Continuous Data Protection which can also replicate with near zero time lag.  Something else to check out depending on your infrastructure.

Hi @AShaikh! Has a number of replication scenarios and typically works between sites as long as you are well connected. There is an additional option with Veeam of working with what’s they call a cloud connect partner, replicating to a managed IaaS environment that does not require VPN connectivity at all, just outbound Internet service with sufficient bandwidth.

Welcome to the community @AShaikh, many options are already mentioned.

You have also the option to built your replicas from existing backups (if you don’t want to process the production VM more than once a day or if this fits for your RPO)

If you also want to built more on DR plans, test and report RTO/RPO you should have a look at the Veeam Recovery Orchestrator. 
 

best, Markus

Thank you everyone for your suggestion, much appreciated.

I think this option “https://helpcenter.veeam.com/docs/backup/vsphere/replication_components.html?ver=120” is more suitable for own scenario. 

I will get the trial license and test it before we go ahead with purchase.

Other tip I will add … look at doing a pull replication e.g. Veeam server at DR site pulling info over the SD-WAN , rather than a push from Production side of SD-WAN. That way if production goes completely dark, you still have control over replicas

Does it mean setting up another veeam server at DR site and add all repository. Then pull data from production repository?

No the suggestion is to have the VBR server at the DR site to do everything.  No extra server.

This will increase backup completion time, so this is not an option.

Then you can have a standby server at the DR site in case the main site goes down.  Otherwise DR is harder without a VBR server.

I checked the Backup Copy job and there is no way to connect to DR VBR server as target.

If you are sending to a repository in the DR side you connect that to the VBR server once it comes up.

I can connect to repository to DR that’s not a problem. But when there is a disaster you dont have VBR at DR site to restore.

Exactly why the recommendation or standby server there.
