Who Do You Call?

Matt Steinhoff FiremanWho do you call when your computer crashes and burns a couple of days before you are supposed to take off on a road trip? Kids Matt and Adam, of course.

After I had tried everything I knew how to do, I initiated Plan C, which was to haul the machine up to Kid Matt because, as Kid Adam, dodging the bullet, pointed out, Matt’s the guy who built it and is most familiar with all the pieces/parts.

Two flaky drives

Matt called this afternoon to say that my operating system RAID must have had TWO bad drives because he was seeing corruption on what I thought was the good drive. He replaced both of them and restored them from backup. (Hint: when the system reports that you have 17 seconds left to completion, go out to dinner. It lies.)

Hit some Kryptonite

Matt Steinhoff Halloween 1979About an hour later, he called to say that he had run into a big snag: Acronis, the backup program I use, won’t write a file to a partition bigger than two terabytes. My data RAID was made up of four two-terabyte drives. Acronis wouldn’t even see them.

I had never run into this problem because I had never tried to restore everything at once. The few times I needed to go to a backup, it was just one or two files.

Plan D was for him to copy just a couple of the critical directories, then I would restore about 90 percent of the remaining data from a portable external drive I keep around “just in case.”

Backblaze is Plan E

Buy From Amazon.com to Support Ken SteinhoffJust this week I got an email from Backblaze, my cloud backup provider, saying that they would now be able to write your backups to up to a 4 terabyte external drive and send it to you overnight. (What they DIDN’T say was that for large quantities of data, it might take up to five days for them to copy it all TO the drive. Still, downloading it, even with a fast internet connection, would have taken about three months.)

So, I sent them my credit card number for a 4-terabyte drive containing 599,771 files and 3.296,468 terabytes of data. It cost $189.

That’s the reason you need to click on that Amazon link at the top of the page (or here) to keep me from holding up a cardboard “Will Work For Hard Drives” sign at the intersection. Amazon purchases you make through that link give me about a 6% kickback without costing you anything extra.

Here are two earlier stories I did about Backblaze.

 Plan F

Adam GeekIf Plans A, B, C, D and E didn’t work, I was ready to call in Kid Adam. He LOOKS like he could solve a computer problem if the firefighter and Superman struck out.

 

Restore, Restore, Restore

The message two days ago was Backup, Backup, Backup. The mission today was Restore, Restore, Restore.

Well, life is good. I replaced two external devices that I used for data storage with one Drobo S that holds five drives and “stripes” the data across all of the drives. I can lose one drive without data loss. I COULD have formatted it so I could lose two drives, but I would have lost storage space. So, my five drive bays are filled with two 2TB drives, 2 1.5TB drives and an oddball 320GB drive I had kicking around. After the overhead the redundancy claims, I have 4.82TB available to me. (I can remember when I was impressed to get 1.4MB on a 3-1/4″ floppy.)

Drobo was easy to install

Most of you won’t need that kind of storage, but if you do, I highly recommend the Drobo. My kid has one like mine at home and an eight-bay at his office. He kept trying to convince me to move in that direction, but I hate to spend money until and unless I have to.

The nice thing is that you can mix and match drives, then put in bigger ones when you need more space. You don’t have to go through any big gyrations to make it work. The thing that took the most time was getting a stripped screw to let go of the side rails in my old device. Drobo installation consisted of loading the Drobo Dashboard software, sliding the drives in the bays (the cover, a nifty translucent plastic that lets you see diodes and flashing lights is held on by magnets), plugging in the power and and data cables and formatting the drives (took five minutes).

Backblaze worked

I touted Backblaze’s cloud backup system in my earlier post, but I have to admit that I wasn’t completely confident that it was going to be able to handle a 228GB zip file, but it unpacked clean as a whistle.

If you’re not backing up your data on a regular and reliable basis, I highly recommend this service. It’s five bucks a month to back up unlimited amounts of data. If you click on this link or the image above, it’ll take you to Backblaze. If you sign up for the service, I get a tiny piece of the action. Since the darned service is so cheap, trust me when I say “tiny.”

Salting the elephants

I used the expression “salting the elephants” when a vendor tried to tell me that he didn’t need to prove that his backup system actually worked. He said the restore was so reliable (and so much trouble to make work) that I should just trust him that it would perform as described. (The elephant photo, by the way, was taken at the Town Plaza.)

“So, basically, if I buy your system,” I said, “I’m going to be salting the elephants and assuming that just by HAVING it, I’ll keep failure at bay. Is that your pitch?”

He looked at me quizzically, so I filled him in.

A guy is sitting on a park bench minding his own business when a stranger in a suit sits down next to him. They nod, but otherwise ignore each other. The stranger opens his coat, extracts a salt shaker and shakes it over his shoulder.

Guy One thinks this is unusual, but shrugs and ignores it. A few minutes later, Guy Two repeats the action. This goes on several times until Guy One just has to ask.

“It’s none of my business, but what’s with the salt shaker?”

“It keeps the elephants away,” was the answer.

“There aren’t any elephants around here.”

“See, it’s working.”

Unlike the vendor, I have actually done a restore with Backblaze, so I feel comfortable recommending it.

Backup, Backup, Backup

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.
