The Computer Backup Rule of Three - Scott Hanselman

[doodab]

Heard another scare stories about Drobo to run a mile from it (the idea that the only way to recover from a failed Drobo box is another Drobo box rather put me off).

That's true of most hardware RAID solutions though. They all use a propriety format for metadata about the configured LUNs and layouts. Certainly with LSI & Adaptec cards you can't just pull a drive out of a set and expect it to be readable elsewhere, and of course with RAID 0 and especially 5 there is no way you're going to plug the drives into another random RAID card and have it work. I'd expect most RAID NAS to be the same.

I don't think people really think about this when they stump up the cash for a NAS box not realising it's probably more likely to give out than the drives are. That's why I've never bought one (well that and being able to get an 8 port LSI raid card for less money )

With software RAID you should at least be able to split a mirror and mount one of the drives elsewhere, as long as it's a compatible OS.

I have a 1Tb USB external drive plugged into my NAS, and it backs up all my accounts, music and photos at 3a.m. every morning.

Some really important stuff I stick in DropBox too, which means it gets spread over 3 machines as well.

I duplicate stuff across 2 main machines, one with a 2TB USB disk to cope with work in progress and the other with 3 x 1 TB USB disks which I rotate.

I really ought to get some extras because this lot is a few years old now.

P.S. I don't have masses of videos/music/photos so the above is quite adequate.

These guys were recommended to me recently

Online Backup & Data Backup Software | Backblaze

Looks cheaper than Amazon. BTW, Dropbox is based on Amazon S3 so I heard

EDIT $5 per month for unlimited storage !

Speaking of BackBlaze,

Because Backblaze has a history of openness, many readers expected more details in my previous posts. They asked what drive models work best and which last the longest. Given our experience with over 25,000 drives, they asked which ones are good enough that we would buy them again. In this post, I’ll answer those questions.

BackBlaze article: What hard drive should I buy?

Of course they are talking about most cost effective in the context of a large fleet of drives. I take the view that with the small number of drives I have spending a bit extra is probably worth it.

Dunno how relevant this observation is, but as a non technical type I can follow some of what is being discussed here so... how technically minded are the people who are going to have to use this solution?

I'd expect that a physical 'box' would be the easiest thing to understand and if ever there is a problem then it's something which can be taken to find someone who can help. As has been mentioned, this can be duplicated to mitigate any loss from fire/theft etc.

Is that a consideration in this instance?

Why such a surprise? Hitachi Data Systems make serious SAN systems and are probably the only such vendor who also make their own HDD. They certainly have the expertise.

wasn't my experience a few years ago.

If it's long term backup with infrequent access then perhaps Amazon Glacier is an option.

It is a backup (I would still want to have another version elsewhere as well).
