I have a client that has about 20TB of data the needs backing up on a daily basis. Their environment consists of 3 physical servers and 4 Hyper-V VMs. One of the physical servers is configured as a virtual host while the other is the replication server. The VMs are configured to replicate every 15min. Both physical servers have 10GB NICs that are Teamed for load balancing.
We’ve installed two Synology DS918+ Plus NAS devices each with 8 x 4TB drives. Our idea here was that data would back up to the first NAS then we’d configure the secondary NAS as replication of the first, this second NAS would then be located off-site.
We’ve tried running the solutions on the VM host and have installed the software on each of the VMs to backup individually, each solution takes anything from 45 - 670 hrs to complete a single backup which is not at all productive. Our DR acceptable time is maximum to 15hours.
