Inexpensive NAS for over 4TB backups - recommendations?

RAID-0 is the only way. If you are wanting long-term archival, it is not safe. If you are just wanting a current snapshot of the pro, it might be good enough. I recommend a UPS in any case, but especially if you go with RAID-0.

We keep everything on HCL-compatible UPS (with USB monitoring).

On main goal with the backup system is not archiving. We mainly want data protection and recovery in case our main NAS fails or (as in the current case) we need to do a factory reset for whatever reason.

BTW, the RN102 also has WoL, so you could alternatively boot it up from one of the Pros on schedule. I haven't played much with that feature.

Would be great if the some basic scripting were possible with backup scheduling - i.e. run backup on day/time, then power down when finished. Feature request! :wink:

It seems like we'd get the most flexibility with a RN104 as we could run that in X-RAID2 single-redundancy mode and still have enough future capacity to back-up the Pros in dual-redundancy, even if we fill all the Pro's slots. I'll have to see if we have enough budget to do this.

Re: snapshots - I've never used this feature. I get the impression it works a bit like Time Machine on the Mac, copying differences but making each instance look like a full backup so it takes much less time than a regular back-up?

Do snapshots have any big advantages over regular Frontview incremental backups?

Can snapshots be used for full volume recovery (i.e. recover C volume)?

Can snapshots be saved to a backup drive instead of the source drive?
