USB or Network HD for backup - WD Personal Cloud Storage
I currently use a 2.5 TB Western Digital external USB HD for backing up my NAS. However, it takes about 12 hours and some change to backup 2 TB of data. Granted, this is only during a full backup on the first run through with RSync taking over from there on incremental changes. I'm getting close to a point where I'll need more backup storage space to the NAS. Now I can simply pickup another USB external HD of a larger size such as a 3 or 4 TB drive or I could improve the transfer speeds by grabbing a network drive. One such drives I have been looking at are the networked WD drives. Has anyone used one yet?
For example: http://www.amazon.com/Western-Digital-Personal-Cloud-Storage/dp/B00439GMJ2/ref=sr_1_1?s=electronics&ie=UTF8&qid=1355060884&sr=1-1&keywords=western+digital+external+hard+networked+drive. The price difference seems negligible compared to a USB of similar size. Anyhow, I would be curious about other's experiences with such a device. I also saw WD offers a DUO NAS unit that seems to be in competition with the Readynas.

- I use older ReadyNAS for on-site backup, so I haven't looked into these drives.
I like the idea though, it seems to me that it is better to do your backup to a device that isn't directly connected to the NAS (it seems to me that it reduces the risk that a PSU failures or power surge/outage on the NAS would trash the backup drive).

Agreed, and an alternative approach I may use is upgrading my NAS from 4x2TB to 4x4TB and repurposing the old 2 TB drives in external cases that support Gigabit connection. I could then use those drives to support backing up my NAS but of course would do this over time since drives in the 4TB area are not cheap. This would also allow me to extend the life of my old drives and ensure I get my monies worth.
