Title: Swapping in a 3rd HD as offsite backup?
Post by: kimgkimg on March 24, 2009, 01:49:50 PM

Sorry guys, I'm a bit of a noob to this whole Raid 1 thing.  I had read fordem's thread on drive swapping from March 2008 in which he said don't touch the drives unless absolutely necessary.  I had also read somewhere that someone was swapping in a 3rd drive on a monthly basis in order to have a backup drive with snapshot image of the array.  Is this a good practice?  I was thinking it could be used for restoration in the case of full failure of the array machine.

I think that should work fine (but I'm no expert and I didn't stay at a Holiday Inn Express last night either).

One review of the 321 pointed out that the unit needs to see a blank drive for it to start rebuilding the array.  So you've got a bit of extra hassle since you can't just pop the third drive if it already has old backup data on it...you'd need to put it into a PC (or get a drive eSATA dock, a much more convenient choice) and delete the partitions...but from there it should work just fine.

Home NAS, from what I'm learning has a problem with backing up. The vendors all think we are backing up our PCs to the NAS devices. I'm not doing that and I guess you're not either. I'm using it as a file server. The system needs shadow copies or Samba snapshots or something. I'd like to suggest this to D-Link. It would be awesome if they implemented it.
