I’ve had a very frustrating (and expensive) last two days. I’m a pessimist who believes that Murphy wasn’t an only child. I usually have not only a Plan B, but Plans C through E. In fact, a pessimist is someone who is actually DISAPPOINTED when Plan A works.
Optimists, on the other hand, don’t have Plan Bs because they are SURE than Plan A is going to be successful beyond anyone’s dreams.
How do you fight Murphy?
I have about 50% of my data on a pair of external 2-terabyte drives. The drives are mirrored, so the information is duplicated on both drives at the same time. If one fails, then you slap in a replacement and the mirror rebuilds itself. We used this technology on equipment in our telephone switchroom, and it saved our voicemail system and what we called the “cash register,” the equipment that supported our circulation and classified advertising call centers. There’s no more sinking feeling than seeing the alarm, “Drive Fail>’
On the other hand, there’s a great feeling of satisfaction when you slide in the spare and watch your world – and your job prospects – become infinitely brighter.
Backblaze puts out the fire in your tummy
To be even safer, I back up the mirrored drives to a second external drive, and I also use on offsite, “cloud” backup system called Backblaze. You can’t beat the deal. It costs five bucks a month and you can back up unlimited amounts of data. (It was an even better deal for me: Son Adam prepaid a year of the service as a Father’s Day gift.) The advantage to a cloud backup is that it’s not in your house where it can get stolen, flooded or burn up.
I wasn’t their normal customer. I have so much data that it took about four months to upload it all. One it’s there, though, it constantly monitors the files on my computer and sends changes to the cloud almost immediately.
I just signed up to become an affiliate, so if you click on the Backblaze logo above, or this link, I’ll get credit if you sign up for the service.
If you are an optimist, this is a good Plan B. If you are a pessimist, this will probably slot in at about Plan C or D. Five bucks a month is less than some folks spend in Starbucks a day and it’ll let you sleep a lot better.
So, what happened?
Last month, my RAID drives gave me an alarm that one of them had taken a dirt nap. These drives have names. The bad guy was the primary, the good guy was the secondary.
I ordered a replacement drive under warranty. It arrived in a couple of days. I popped it into the slot and watched with satisfaction as the primary synched up to the secondary in about six hours. All was good for about a month. Then, two days ago, the drive in that slot failed again. The vendor had sent me two drives by mistake, so I pulled out the replacement and replaced it with the second drive.
Just before I turned the drive back on, I decided to do a backup on my external drive G. I kicked it off just before going to bed and it finished just about breakfast time. That means the data exists on the secondary, on Drive G and in the cloud with Backblaze.
Life just got uglier
I pushed the new drive in, powered up the enclosure and got an error message that the drive had to be formatted. Format is a scary command. If you screw it up, you’ll wipe out all the data on the drive. To be on the safe side, I removed the good secondary drive, then formatted the primary. I’d never had to do that before, but…
I put everything back together, turned on the power, then watched, first with satisfaction, then with horror, that the mirror was being rebuilt. The little arrows were going the wrong way. The little arrows SHOULD have been pointing FROM the secondary to the primary. Instead, they were going the other way, meaning that the blank primary drive was overwriting all my data.
The pessimist in me was satisfied
This was a bad thing, but, at least I had the satisfaction of knowing that I had two other sources of the data, both fresh. I logged into my Backblaze account and started a download of the data. It’s a lot faster to restore from a local drive than from the cloud. (If I had REALLY been in a hurry, Backblaze would have sold me an external drive with my data on it.) Downloading everything on that drive was going to take about 50 hours, even with a fast Internet connection.
Here’s where I made a minor error. Backblaze has everything that was on the drive. When I did my backup to local Drive G, I elected not to copy over a couple of directories of nice-to-have-but-not-essential files. I would have been better off to have requested a Backblaze download of only those files instead of EVERYTHING. It would have saved a lot of download bandwidth and time. Still, this is a nice practice run and will give me a good idea of how good the service is.
THEN what happened?
I decided that the problem was probably in the piece of equipment that holds the drives, not the drives. I pulled out the primary drive, booted up on only the secondary, and copied all my data from the local external drive to the secondary. It worked fine. I decided NOT to try to rebuild the mirror.
I called Son Matt, who has been trying to convince me that I should buy a magic Drobo S Beyond Raid 5-Bay USB 3.0/FireWire 800/eSATA/SATA 6GB/S Storage Array with Drobo PC Backup by Drobo because he had good luck with them both at home and at work. The magic part is that you can put a mixture of drive sizes in it to use old drives or you can upgrade them if you need more storage. Wife Lila is out of town on a cruise ship in Alaska, safely out of cellular range, so I felt safe in ordering the Drobo.
The bad news is that it cost $553.14 (without the drives). (That’s one of the reasons you should click on my Amazon link at the top left of the page. It helps pay for these kind of glitches.)
The worse news is that I clicked on the item to create the links on this page, and saw that the price had DROPPED in the few hours since I had placed my order. A very nice woman said they don’t normally do price matching, but they’d make a one-time exception for me and refund the difference between $553.14 and the new price of $518.49.
Things were starting to come together for my trip back home. I wrapped up the final revision of the Smelterville book, got a haircut, the van got an oil change and new rear shocks, we went out to say goodbye to Grandsons Graham and Elliot, and I made a lot of progress pulling together a video this morning. I even worked in a well-deserved nap after all that activity.
Got an alert this afternoon that my RAID 1 array had gone critical. That’s my boot drive.
Click on the big red Amazon button when you order stuff online. That helps me keep feeding hard drives into my computer and it doesn’t add anything to your cost.
