Replacing ReadyNAS RN312 Drives
Hi all, I have the RN312 running 2x 2TB drives in RAID 1. Recently one of the drives failed and it is running in degraded mode. As both disks are quite old I have ordered two replacement disks....
Thanks. Same capacity but different make/model drives. Also I am running firmware 6.4.1.
I have a backup and I am manually running it right now. However I've never actually had to restore anything from it... so is there a guide already out there to perform a backup/restore in this situation? i.e. config and data?
Seeing as everything is actually working at the moment, I would be able to completely reconfigure and re-do the backup first if I could be doing it a better way.
Also, just to confirm, yes I have gone over these links:

Can't see where it says how to restore data/config. Everything just shows how to backup.
You can do a config backup (note this won't backup app configuration) under System > Settings > Configuration Backup. If restoring this, you should install apps you were running before the reset first then restore the config from the config backup.
As for restoring data from backup, you would do backup jobs in the other direction with the backup as the source and the share on the NAS as the destination.
Hi realmcom,
Since you are looking for an article, here's one that you can check.
Kind regards,

NETGEAR Community TeamSo far what I have done is replace the failed drive with a new one, then replace the other drive with the 2nd new one after the rebuild. I was hoping this would be okay to keep me going, however for some reason since the first original drive failed, performance has been extremely slow, and now that the RAID is optimal once again, this has not improved. So I am running a couple of different backups so I can head down the factory restore option, wipe it and set it up from scratch and restore the data.
Interesting point to note, the first backup I had was an NTFS drive, it didn't take long because it was already used as a regular backup.
2nd backup I ran to a spare drive which I used the ReadyNAS page to format as EXT4. This backed up my entire NAS (approx 1.2TB of data) in around the 4 hours mark, which I thought was pretty quick.
3rd backup I am running at present, also on a spare drive which I used the ReadyNAS page to format, this time as NTFS. It has been going since this morning and is currently just over the 11 hours mark with quite a bit more to go yet.
So does anyone know if the ReadyNAS is supposed to give better performance from one filesystem over another? I find this extremely interesting.
There's an old review that gives the USB 3 backup performance for NTFS at ~16-17 MB/s.
NTFS uses a software package from paragon, it likely is slower than ext.
