I'm about to buy a RN516 with 6 Seagate 4TB 3.5" SATA3 64MB Cache OEM Hard Drive (ST4000VN000) that I will install myself. I currently keep all my media data on a ReadyNAS Pro 6350.I intend to use the RN516 as my new media server with the ReadyNAS Pro as my backup (until I run out of space).A few questions before I start the project:1) Any tips on the best way to setup the diskless RN516 with the 6 new 4TB drives? Should I start expanding with 1 drive or several installed at once?2) Once the 516 is setup, I have 8TB of data to move to the RN516. Is there a faster way than setting up a RSync backup from the PRO to the RN516 through the network?Thanks for your help!

You can install them at once, you will have only a single rebuild, if you add them it will rebuild once per disk added I think (rebuild is very long ;) really, I have a RN104 with 4*4To (same model as yours, works like a charm) it took 38hours to rebuild, the 516 should be quicker but still expect 10 hours for you 6 disks at least). USB3 is faster than ethernet, e-sata is too so if you have USB disk that can keep up... otherwise rsync or FTP I believe the speed is nearly the same, even AFP/SMB shouldn't be that slow IMO. If you don't have gigabit network you may want to get a PC with a gigabit switch (or two gig NIC on the PC). Maybe jumbo frames can help. That said I believe that no matter what you are doing the Duo will struggle and limit the speed anyway so...

Rsync or nfs (over the network) will be quicker than usb because with usb you need to transfer twice.Certainly if you have a gigabit network that it is the case. Using NFS and then editing the backup to use rsync and rerunning it is a good strategy

Yes, the network is a gigabit. I only considered using RSync. I'm interested in learning more about NFS as you seem to be suggesting it would be quicker for the initial backup.Where I can learn more about NFS and how it applies to the ReadyNAS?Thanks

Nfs is a file sharing protocol like CIF/SMB or AFP. Since it is native to linux generally is the fastest protocol between two linux machines. You can easily select it in the backup menu.Rsync is good at incremental backup and full preservation of owners and permissions. If you edit the backup job after the first time you run it to use rsync, then subsequent backups will use that. The remote share needs to have both enabled.Note that if you create a new backup job, it will do a full backup the first time it runs even if the files are already in the destination share. You need to use the editing trick to avoid that.

Excellent! Great tip.Once the PRO is running reliably as an Rsync backup NAS to the RN516, is it possible to backup to the PRO from a remote location (my office)? I'm worried about chewing up too much bandwidth once I make a connection.Thanks

Could you try running the backup job with e.g. /Documents/ in the exclude list.

I'll give that a try once the 6350 finishes it's last backup job from the RN516.

All Backup Jobs were successful with the exception of the Movies folder. It's still backing up from the RN516.

Is there any way to test whether the backup is still working or has it stalled? The Movie Share is very large and it's moving every file since this is the 1st backup to the ReadyNAS Pro.

I don't want to attempt a backup job that is scheduled from the RN516 until this Backup Job is completed.

If you have SSH I think backup job logs are stored in /tmp while they are in progress. So you could examine that to see if it changes.

I'm not sure what you mean by running backup job with e.g. /Documents/ in the exclude list.

If I run the Backup job (on the RN516) for any share (Documents, Music, Movies, etc), I end up with a 2nd embedded folder (Music/Music) in each of the backup Shares on the 6350.

If using Rsync there is an exclude list option

I'm afraid I've lost you there ... I could not find an "exclude list option" in Rsync in either Frontview (for the 6350) or in OS6 (for the RN516).

It should be available for both in the backup job settings.

What firmware versions are you running on each NAS?

I'm afraid I don't know where to look for the "Exclude List Option".

Firmware: 6.1.9 for RN516
Firmware: 4.2.27 for 6350

It is only available when using the Rsync protocol.

Which NAS do you wish to run the backup job on?
