what is the fastest way to copy data to the NAS from an external source?
Our company bought the Open-E NAS-R3 Enterprise version for a new 24TB RAID, now I have the problem to copy around 10TB of data to the new NAS. The Open-E NAS and the external source (a system with RHEL and an attached RAID via FiberChannel) are connected via Gigabit (bounded).
What is now the fastest way to copy the data (with all permissions and UID/GUID intact) from the old RHEL system to the new Open-E NAS system? I thought maybe rsync would okay but how can I use rsync with Open-E NAS? Is it only possible to mount (NFS) the share from Open-E NAS and then copy via rsync the data to Open-E NAS? Or can I connect directly via rsync to the Open-E NAS system?
