That’s not a backup disk, it’s a mousetrap

Hard Disc_Shattered_Generic_

I’ve just had one of those scary conversations with someone about backup. The one where your reaction to their interpretation of “external backup disk” leaves you gasping for breath for such a prolonged period that you make a right mess of explaining that they have taken leave of their senses.

So, on the off-chance he recognises himself in this blog, I’m going to have another go at explaining his error: in part because I want to make sure his type of mistake is clearly flagged amongst those who have to clean up after a data-loss disaster, and also because my mind is still very full of the rich variety of disks I saw with their rusty, iron intestines all spilled out on the clean room desks at Kroll Ontrack, down in Surrey, a couple of weeks ago.

My friend said to me: “I’ve got my data saved nicely onto one of those external disks”. No problem there, you might say. Prudent fellow. But then I saw he was pointing to one of those plastic cased USB external drives – the ones you see going for a bean and a smartie in high street gadget and electrical retailers.

These, I don’t like, because it has been my experience that they are not so much a backup, as a mousetrap for data. Let the data wriggle up nice and close to the cheese, let it get lulled into a false sense of security and SNAP! – the damn things die on you.

Once I’d stopped hyperventilating, I gently suggested he might like to consider a NAS device

Most of the ones I see will just about let smallish amounts of data come back off if you strip off their nasty plastic outer casings, equally nasty and sharp-edged metal bodies, and let the gasping overheated cheap-as-chips physical disk out into some airflow.

I wasn’t especially surprised to see that Kroll Ontrack’s forensic imaging machine pool has lots of those dual-fan piggyback drive coolers, because so far as I’m concerned, the only good drive is a cool drive, and those “backup device” disks are easily divided into two tribes: the fanless, hot-running Mousetrap, data-losing sort, and the backup devices that come with a sensibly sized case that can’t fall over, equipped with cooling fans.

The bit of my conversation which left me truly flabbergasted was when my friend said: “yes, got all my data safe, I moved it all off the laptop, and on to the backup disk.” In other words, because he’d been told over and over again that the USB drives were the best means of backup, he’d gone one stage further, and decided they were the best place for his only, sole, solitary, primary and final copy of his data. Nasty, unreliable, flaky laptop! Lovely, friendly, trustworthy (if a tad hot to touch) backup disk.

Once I’d stopped hyperventilating, I gently suggested he might like to consider a NAS device (I plumped for the Netgear ReadyNAS Duo, not out of a mass of research but more in the manner of a man reaching for a thrown lifebelt in a category-five hurricane), because these are rather more expensive and therefore better made, with more of an eye for longevity than the kickabout bargain-basement USB drives.

He looked intently at the ebuyer.com page for the ReadyNAS Duo and spotted the nice rubber feet (”So that will stop me knocking it over with my mug of tea then”) and the LAN port (”So I can plug it into my router?”) and the origami cutouts of the system fan on the back (”how is it with cat fluff?”).

I believe I have convinced him that, if he attaches any value whatsoever to his data, this is the right place to go for a continually available, live copy of his files. He may just about have worked out that this is best when combined with software that allows more than one copy of everything to be stored, once on the laptop and again on his nice new home backup repository; but I’m steeling myself for another bout of misinterpretation, cavalier purchasing, and rampant high-street technological misrepresentation.

    3-2-1 Rule. You might like to try and explain the rule to him.

    NO FILE EXISTS, if there aren’t:
    At least 3 copies
    On at least 2 different mediums
    And at least 1 of those is off-site.

    I’ve got 3 and 2 down and most of my data is also oned.

    I have a laptop, an iMac, 2 USB drives (with sufficient ventilation), a ReadyNAS Duo (appauling piece of kit really, but cheap, one of the drives failed and it promptly replicated the new, empty drive onto my full drive, when I stuck it in! Luckily, I didn’t trust it and had made sure all of the data was copied to one of my other machines!).

    I also replicate most of the data in the cloud. Music and RAW images being the exception. I did use Carbonite for a while, but it didn’t work well with Apple Apeture, every time I added a new photo to the collection, it reset the backup count to 90GB!

    Now I PIE (Pre-Internet-Encrypt) my files and store them on Skydrive, GDrive and Dropbox.

    David, that’s a bit of a leading answer. Do you mean you’ve put 90GB on the cloud? Cause I doubt it!

    Spindles and Meteorites. Data is increasingly transient the closer it is to “one spindle” or the path of and “one rock”. Increase the spindle count (HD,Tape or medium) and put them so far apart you’d need a cosmic event/flood/fire/bankruptcy so large data is the last of your worries.

    @Steve, I’ve got 229 GB backed up using IDrive for Windows running on my WHS v1 (mainly RAW images). The initial 60 GB took a week or so to upload, but everything else since then gets quietly uploaded over a night or two. Everything that is important to me is on the main PC (4 disk raid10), on the WHS (duplicated drives) and in the cloud.

    I have the original data on drive 0, a ‘daily’ backup on drive 1, a weekly backup on drive 2 and (all 110GB of it) a skydrive copy for ‘offsite’

    Daft question coming, but what the heck?
    Is PC Pro’s A-list recommended external drive – the Verbatim Store ‘n’ Go – a mousetrap then? If so why is it recommended?
    Puzzled

    Local copy on 5 1/4 hard drive plus one on JustCloud. My nice new fibre-to-the-cabinet has allowed me to stick nearly 1Tb up there in a couple of days :D It’s the first time EVER that I’ve felt smug about my data backup! I just hope my direct debit never misses a payment………

     
  8. Steve Cassidy Says:
    March 5th, 2013 at 10:19 pm

    No Sean; the Store n Go’s are 2.5 nch (ie portable) form factor. The stuff I qualify as Mousetraps are the bigger 3.5’s, which have desktop mechanisms in them that expect to be mounted in the vicinity of a cooling flow of air..

    Steve, with Carbonite, I had around 200GB in my cloud backup, but the default way Apeture works (one big database) means that every time a photo is added to the collection, Carbonite noticed the file change and wanted to upload the whole kit-and-kaboodle again. That is why I stopped using it and switched to using normal cloud services, like Skydrive et al.

    Given the lower limits of the Cloud “Drive” services, I am converting my RAWs to high quality jpegs and storing those online, along with the 5 local copies of the raw files.

    Google did a study a few years ago which appeared to show that cooler drives had an increased chance of failure, though this study mainly concerned drives that were in operation 24/7, but interestingly enough “consumer-grade”

    You can never have enough backups, that said; you store 5 local copies of your raw files David? I’m not sure what you are shooting and I suspect you have far less data than a professional user as obviously more backups are a good thing! But RAW files from my 5DmkII are around 30MB each, if I was to store 5 copies of these I’d be looking at 150MB for each set of copies for just a single image, and on a regular day of wedding/event shooting 800 to 1200 images, that’d be 120GB to 180GB of data for the 5 copies. I’m not sure what local storage you use, but as I might do an event 4-5 times a month, I doubt very many people who don’t work at a data centre have access to 8-10TB for a year’s backups… Plus JPEG conversions, working retouching 16-bit TIFFs (which file sizes can be vast), Lightroom catalogues etc. Personally I backup to a Synology NAS (with different brands of HD populating the RAID for safety), as well as a Mac and PC, plus irreplaceable files in the cloud pre-encrypted on Dropbox, DVDs for archive backups, although keeping a separate set accessible on a NAS.

    The 3-2-1 rule is very sensible. I have had a little experience with a WD Passport Drive. 2 months old.It fell a short distance and sustained what I would call a minor knock. However the result was it died. The problem was that this was during the course of a Windows restore. So I had to restore to an older backup (2 months previous) as I assumed this gadget was doing the job reliably.
    Aha you may say, lets get at the disk inside the box. The box is easily opened. It is a non standard interface into the plastic container. There are 6 unidentified pins beside the interface but no one knows how to power the device off these and restore. There is no information on the WD site. Inside the plastic box, there is very limited cushioning against impact. The drive cannot be separated from the interface card. There are no user serviceable parts. You cannot mount the drive on another device. The Passport should be treated as disposable short term storage as opposed to a reliable long term back up solution. Ontrack £70 to look at. Maybe £500 to recover. Factor this in whenever you buy one of these devices.

    I have “local” backup to an external USB HDD, which I rotate with a “off site” HDD, and I have over 320GB of that data backed up to the cloud. I’m hoping that will cover most scenarios!

     
  14. Steve Cassidy Says:
    March 6th, 2013 at 12:34 pm

    Jez, my impression is that the sudden collapse in durability of “consumer” drives follows almost immediately from the date of that report. Rather like the old story about the GM engineers sent round scrapyards to figure out which car parts could be made cheaper…

    Maybe Google meant for that to happen. “Hey, don’t store your life on those flaky desktop drives, store it in on Google Drive, and use a Chromebook too. We’ll search it for you :-)

    @isofa I have 1TB USB drives and 2 2TB drives in the NAS. I make about 100GB of images a year at present, so the amount of space needed is tolerable at the moment, especially once I’ve weeded out the rubbish.

    But uploading a couple of hundred GB of RAW images isn’t really an option on normal cloud storage. Something like Carbonite, which has a flat rate for your complete hard drive is a good option, I am thinking of getting a new licence for my Windows machine.

    After going the mousetrap route a long time ago, and having the drive fail on me, I now only use external hard-drive enclosures for my backup drives. They take any 3.5″ drive, most have quick release mechanisms and I’ve had no failures yet (touch wood).

    @David Wright – I wonder if something like Crashplan would be able to backup your Aperture database? I know when I upload large files to Crashplan+ online, it only uploads the changes made to the file and not the whole thing.

    From their FAQ: CrashPlan uses advanced data de-duplication and block level incremental backup. At a very basic level, this means that once a file is backed up, only subsequent changes are sent to your backup destination.

    Couple of questions.
    Can anyone point me towards some decent 3.5″ external caddies with fans etc?
    Currently just have a fanless icybox although I think it works reasonably as a heatsink.

    My general backups are done with True Image, but what is a good solution for doing a direct file to file backup rather than having a single backup file/archive that can only be read with the backup software?
    Would much prefer this for my critical data.

    @David Wright, have you tried backblaze? That works fine with my aperture library.

    I use an external time capsule for local backups, along with an external drive set up to be a vault in aperture and backblaze as an offsite backup for if things go really wrong. I have around 600GB backed up to the cloud now through backblaze and it only costs around £5 a month. I’m very impressed with the service, mainly down to the ease of use and how cost effective it is.

    I highly recommend Symform. Bit like a community provided distributed encypted backup system, admittedly more for enterprises and DR offsite backup rather than Dropbox style usage. But it works really well, and it’s free – just donate more storage than you’re backing up and you pay nothing. No storage limits for a free account!

    It’s supposed to be used on high end kit but I can report that it works just fine on an old netbook too…

    @Paul B – I’m more or less the same, except I’ve always used an enclosure. Used to use an icybox when had IDE drives. Now use Sun Bright eSATA and USB.
    @Andrew – I’m not sure any of the external enclosure caddies come with a fan. Mostly because the power kit is all external, and they generally have enough internal space for some airflow, as an example my enclosure comes with a mini heat sink.

    As a question: does PcPro review external enclosures? They are one of the tools of a system recovery expert yet… rarely get any mention, anywhere.

    Jez – Google are offering free Calendar and Email services, with Cloud backup and most importantly Sync, unlike MS. I used to use Outlook, but because they are incapable of making it sync with either Android or Google (or Apple? Or anybody?) without a shedload of cocking about I gave up and moved to pure cloud. Now my Calendar, Contacts and Email are readable from Chrome on my Nexus phone, my iPad, and my home PC automatically. And its free. Oh, the evil Google, giving away so much for free! And how nice of MS to charge a fortune for uncooperative limited-life programs! I see your point, Google really are the root of all evil.

    After my last epic fail at protecting my data onto DVD’s, I invested in an iomega cloud storage NAS Box with 2 2gb green drives.
    Touch wood, I haven’t had any problems since.

    If you are the kind of person that has an old desktop lying around, then it’s very easy to turn it into a home server after of course fitting brand new hard drives. If you don’t like the idea of spending money then Ubuntu or whatever will do a fine job of hooking into your home network and distributing a simple folder share. It’ll also run dropbox. If you go the Windows route then you can have sky drive running to it as well. Be sure to set dropbox up with lan sync for quick distribution across a home network.

    Katsu999 I use outlook.com email and it distributes email and calendars to my Android device without any issues. Also use outlook client on one machine for a laugh and I’ve created an email loop for one address whereby everything goes through gmail and is auto archived before being forwarded onwards.

     
  28. David Wright Says:
    March 10th, 2013 at 10:04 am

    @Rger Andre, Katsu999 was probably using a POP service somewhere with Outlook desktop. The POP services don’t sync well and don’t offer the calendar etc. facilities.

    I too use Hotmail/Outlook and never had problems syncing it with Android and iOS, the same goes for Exchange, that works well on Android as well. Likewise I have GMail on my Windows 8 machine.

    That reminds me, I haven’t checked my iCloud account for a couple of weeks…
