Hi guys, I've just got myself a DNS323 (v1.08) but have not gotten hard disks for it yet. Have a few questions regarding this device hope you guys can help!
1. I intend to get a 1TB Hitachi disk,and start transferring my files into in. A few months later, I'd get another of the same disk and configure it as RAID1 to backup my first disk. Is this possible and will I encounter any data integrity problems when trying to do this?
2. Lets say a few years down the road I ran out of space and would like to get a bigger capacity disk. Can I simply unplug one disk from the device, slot the bigger capacity one in and expect the device to mirror the data to the newer disk ???

First off, RAID is NOT backup! The only purpose of RAID in this box is to allow continued access in the event of a hard disk failure.
If you want backup, use a real backup, but don't count on RAID as a backup.

The answer to the question you asked is YES, the answer to the question you were intending to ask is NO.
Yes - you can replace a disk in the RAID array with a larger capacity one and the unit will rebuild the array using the larger disk, BUT, the RAID array will remain the same size and the "additional" capacity is lost - so, NO, you cannot migrate to larger capacity disks that way.

So, if I wana do a backup for the stuff in my device, is there a script available that I can use that runs automatically to backup files in hdd1 to hdd2?

Alright! Thanks for the info
