The network mode is not recommended due to potential network bandwidth constraints and utilization resulting in low data transfer speeds extending backup and restore times. In Network mode, data is transferred via the ESXi host over LAN using the Network Block Device protocol (NBD). VM data moves through the SAN, circumventing ESXi hosts and the LAN. In this case, Veeam uses VMware’s VADP (VMware vSphere Storage APIs – Data Protection) to move the VM data (vmdk files) directly from and to FC and iSCSI shared storage over the SAN.

I will provide details about the SAN mode setup and how to avoid common pitfalls.īefore we jump into configuration let us see what is SAN mode and NBD(Network) mode.ĭirect SAN access transport mode is best suited for Virtual Machines with disks located on shared VMFS volumes which are connected to ESXi hosts over iSCSI or FC protocols. However, ensuring that SAN mode is utilized can be sometimes challenging. So maybe today thats not a problem anymore now.Īnyway i will try to Veeam-backup my 6TB VM later.In this blog, I discuss Veeam’s SAN mode configuration which delivers optimal data transport. Users must be able to create dirs but should not be able to change files owned by other users, and so on.īut well, a lot of time passed by, and maybe today's NAS' OS like QNAP and synlogy and lenovo, might alreaedy have become also more enterprise-like. Like for example you need very special permissions on the Active Directory user-profiles share.

Then sometimes they don't behave like a windows server. when it comes to emulating granular NTFS permissions. There are some situations where NAS as a productive system is making problems. I have considered NAS mainly as a backup device until now. Now i have to change it back.įor NAS to NAS solutions: No i was not yet aware of it yet. Yes we should have better left it as it is by default: as a dependent disk. And if it's gonna take too long for that, i will switch to forward incrementals with synthetic fulls. 3TB of change, yeah, it'll take several hours, just leave enough space for snapshots.
Incrementals are going to depend on how much changed, but if it's small it's usually not more than 10 minutes. It'll take some time but that's up to your storage really. I use Veeam for up to 20TB file servers, it doesn't care. Have you considered a dedicated SAN or NAS solution as a file server ? There are many enterprise grade NAS or 3 NAS solutions that I can suggest.NAS to NAS HA with backup to NAS. Part of the statement is is NEVER a good idea to have a human perform snapshot of VMs unless if is for a short time like for performing Windows updates or other critical updates and the snapshot is manually removed after updates is completed (best practice of not more than 72 hours).Ĥ. "Because im not really sure weather its a good idea to snapshot a VM of this size.
Snapshots are a way to quiescence the VM.the only other way to quiescence a VM is to power it down.ģ.

If you have a backup software and it uses VMware snapshots, let the backup software handle the snapshots and do not modify settings further. Some things are set as default for a reason (eg VMDK sector sizes, VM disks "independent or dependent", backup processes). Keep things simple and do not over think things.
A few things I think some VM users may need to understand.ġ.
