Health check during replication?

[FrancWest]

Hi,

in our environment we use backups from backup copy jobs to built the replica's in our DR site using replication jobs. Since health checks take ages on these backups copies I wondered since these job are used on a daily basis to create the replica's are health checks still needed? Does Veeam do the same checks a health check does when reading from the copy jobs to built these replica's?

Hi Frank, how long does the healthcheck take in your environment?
Healthchecks are not mandatory, but help ensure recoverability.

Well some of the cheks is take more than one day for jobs that have in about 2TB of VM data. We have one job (fileservers) that have 5TB of VM data. So I would like to know if creating replica's from the same data also does the check that a health check does and thus the data is not corrupted.

Replication job doesn't do health check as backup and backup copy jobs.
Have you considered using SureReplica?

As for the healthcheck, its performance is mostly defined by the backup size and by what the storage can provide in terms of the read speed.

[FrancWest]

Yes, I know, but when health checks are running all other copy jobs going to the same storage are very slow due to the iops the health check requires. So that's why I thought it might be useful that a health check is also being performed at the time the data is read when creating the replica's.

Sure replica is an option, but in our case the destination esxi host isn't capable of running many vm's at once (we replicate 60 vm's). Only during DR we vmotion the VMs to multiple production like esxi hosts.

Hi Franc, no, replication job doesn't verify data on reading as backup copy job does. Thanks!
