ReadyNas Ultra2 RNDU2000 Swapping Hard Drives
Hi, I have a 2 x ReadyNas Ultra 2 chassis with 5 Seagate 2 TB disks... 2 in each and 1 spare. I only use one chassis live, the other was purchased as a replaement when I originally couldn't acces...
- Thanks, I clicked on the link but I get file not found...
The disks aren't precisely identical, as each has some metadata on it the identifies it as a physical volume in the RAID array.
The process can work if you are careful, but isn't one that is recommended here. One reason is that the SATA drive connectors aren't really designed to be reinserted often. Another is that the strategy requires a lot of resyncing of the RAID array. If the array fails during a resync, then data will be lost, forcing you to fall back on the backup (which might be somewhat out of date).
A better plan is to put your backup ultra on a power-schedule, and set it up to back up your main NAS using the built-in backup facility (using the built-in backup program). I do that myself as part of my backup strategy. It's automatic, and doesn't require doing a lot of unnecessary resyncs of the RAID array.
Ok I understand the risks. The automated back up facility would have to be NAS to NAS, via the network correct? How do I configure the main Nas to connect to the back up Nas? Both would be connected to the same router. I can't see on the Raidar interface how to configure a back up set to another Netgear box attached via local lan only options are to a "Time machine" or an online Netgear vault.
That would be the best solution I agree..

With OS 4.2.x, you use the admin web ui (frontview) by entering https://nas-ip-address/admin
From there you will see a backup control along the left side - if you click that it will expand to include "add a new backup job".
I have one rsync backup job set up for each share of the NAS (and you can also set one up for the home folders if you use them).
There are a lot more details in the software manual (starting on page 88) here: http://www.downloads.netgear.com/files/GDC/RNDU2000/ReadyNAS_Business_SW_05Nov13.pdf
Most of the kb articles are centered on OS-6 now - they can be helpful even with your older OS 4.2 system - the screen layouts are completely different than OS 4.2, but most of the settings are identical.
