Title: how to convert from 'standard' (individual disks) to RAID1
Post by: edmister on September 21, 2010, 01:54:48 PM

Hi all,
I'd like to move from 'individual disks' to RAID 1 on my DNS-323.
I've basically come to the conclusion with all the data that is now on my volume_1, I need to have it safe and also more faster access which I should get with RAID 1.

I currently have 2x 1TG harddisks installed. Only Volume_1 is being used and Volume_2 is full but I can delete everything there.

But when I go into the web admin console, it tells me that when I go to select to change the mode, all data will be lost and harddisk/s reformatted.
How can I only format volume_2 and keep my data on volume_1 for the RAID 1?

Thanks very much in advance.

RAID-1 won't give you faster access, and RAID is not backup.

You'd be better off taking one disk out and putting it in a USB enclosure and using it as a backup.

The safest way to setup RAID1 from existing disks is...

1) make a backup of all your data
2) setup your disks to RAID1 according to the web admin console
3) restore your data from backup

Remember to setup a periodic scheduled backup of your data to keep your data safe
from other disaster scenarios.

I am curious as well how this strategy works.  So..basically you have a USB enclosed harddrive....you plug it in the Dns-323 usb via Shareport or plug it in in the computer and do the backup from Dns-323 to USB enclosed harddrive?

thnx!

Using Shareport would be EXTREMELY inefficient, assuming it is even possible. If you aren't using fun_plug, the best and fastest backup strategy is to copy the files on the NAS to a HDD in your PC, preferably one that is on the bus directly rather than a USB drive.

I'm suggesting using the USB hard disk connected to your computer and make a standard backup.  I use beyond Compare to make an exact copy of the disk contents while only copying the changed/added files.
