External USB drive to back up 6TB ReadyNAS NV+ V1
I have a Raid-X setup in a Readynas NV+ V1 with 4 2TB drives holding approx 6TB of data.
I want to back it up to an external USB drive.
I got a Seagate USB3.0 8TB drive, but so far I can't get the Readynas to see the file system...it sees the drive, just no file system.
The external drive is NTFS, originally had a small boot partition, after the first failure of the readynas to see the drive, I deleted it and reformatted the drive.
That doesn't work. I am currently reformatting the drive in ext3...but somehow doubt that will work.
I want to know if anyone in the community has successfully hooked up a large 4TB or larger external USB drive to a V1 NV+, and if so what make/model, how much screwing around was required to make it work.
Thanks.
...I am attempting to back up the drive, via the network, to a eSATA raid plugged into my desktop computer....you can imagine how quick that is.

That is because the NV+ v1 doesn't support GPT drives (internal or external). So it is limited to 2 TB USB drives.

Actually that is the fastest way to do it. The NV+ v1 transfers the files much more quickly over the network than it can write to USB drives - especially if the drive is formatted using NTFS.
The main challenge is making sure everything is transferred with no errors. You could use robocopy or teracopy (with verification) - though that will be somewhat slower than drag+drop. You could also share the drive, and use an NV+ backup job.
- Yes I am using a network share. It is interesting that it can crate a 8TB raid, but cannot access a single drive larger than 2TB...almost makes the ability to hook up an external drive for backup purposes useless.

The core product goes back to ~2007-2008 and pre-dates GPT drives. I think the largest available drives at the time were 1 TB, maybe even less. There's been some debate here on whether the v1 hardware is capable of supporting GPT or not, but at the end of the day, Netgear didn't add it.
Of course none of the current ReadyNAS have this limitation.
