Veeam8 replication fails after changing source

[robbys]

I've changed the source of my replications from my live servers to my backup repository. I now get the error "Restore point is located in backup file with a different block size (1024KB expected)" on all replications.
Deleting the replicated machine doesn't help.

Robby, most likely storage optimization settings in replication and backup jobs are different. Replica from backup functionality requires the source backup created with the same block size as used in the replication job, if you switch the existing job to get data from the backup file.
