I am currently experimenting with FreeNAS as storage for holding snapshot-based backups of my ESXi hosted VMs. I have been reading about NFS vs iSCSI and had some questions about them.
This is the thread I have been reading: https://forums.freenas.org/index.ph...xi-nfs-so-slow-and-why-is-iscsi-faster.12506/
Basically I understand that NFS with sync writes enabled is a safer option when running your VMs from the datastore, and is almost absolutely necessary for keeping the data safe on a running VM. How will this affect my situation in which I am essentially just copying snapshots from another datastore to FreeNAS? Is this only going to be an issue in the event of a power outage? Or do I need to invest in a good SLOG and use NFS with sync writes enabled?
Thanks in advance!
