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.

Ties That Bind

There’s a closet in the basement that contains some clothes dating back to just past the middle of the last century. (Sure sounds old when you put it that way.)

When you open the door, you see an assortment of neckties. I recognize some of those – and, no, I’m not going to tell you which ones – once adorned my neck. Most of them are fakes.

Cops wear “breakaway” ties so that the bad guys can’t grab them by the necktie and strangle them. Of course, it’s MY contention that strangulation is the primary goal of the necktie.

Knots known to sailors and serial killers

I was a Boy Scout who earned the Pioneering Merit Badge. Not only could I tie every required knot, I enjoyed playing around with ones known only to sailors and serial killers. The only knot that I’ve never been able to master is a necktie.

Even though I got to cover Queen Elizabeth because I was the only guy on the staff with a suit, I’ve had to depend on fakes and Wife Lila to drape respectability around my neck.

Two instructions

My family has two instructions for the day when there will be “two at my head, two at my feet and two to carry me when I die:”

Not in a necktie.
Not in Florida.

Obligatory Isaac report

We came through Tropical Storm Isaac in pretty good shape. The rains pretty much moved on by early evening, but Son Adam, who lives west of town in a rural area got between 10 and 15 inches of rain. His house is on a high pad about three feet above the water, but he has huge Koi (“ornamental varieties of domesticated common carp”) swimming in his front yard. I warned him that alligators have been know to use those as bait, so I wouldn’t get close to them.

Our Comcast Internet connection is still down, so this is going to be a short post tonight.

Malcolm’s New Tree House

Grandson Malcolm’s eighth birthday is coming up this weekend. His party was held at a skating rink last year, which gave me an excuse to write about the rinks in Cape and Jackson. His parents, Matt and Sarah, teamed up with Neighbor Will Hill (he’s the guy without a shirt) to build a “tree house” in the backyard.

Will actually knew what he was doing. I built something for Sons Matt and Adam when they were a little younger than this. It started out as a simple platform with a sandbox under it. Before long, a fireman’s pole and a slide were added. The original structure used a rope ladder with PVC pipe rungs. It could be pulled up to keep Adam from climbing up to the level where he might be tempted by Matt to see if he could fly by flapping his arms.

Building a monkey bars gave me an excuse to add a swing to the mix. There was no overall plan – stuff just got added whenever the posthole digger cried out to make a new hole in the ground.

Time-lapse video

Matt set up his Nikon DSLR to take a photo every 60 seconds so he could condense a 12-hour project into a three-minute video. The structure could be more properly called a play house rather than a tree house since no trees were harmed in the making of the building, still, we CALLED it the tree house. Here’s what a REAL tree house looks like.

Mat made from shopping bags

I described how Mother had turned into a bag lady, making all kinds of stuff out of plastic shopping bags. One of her projects was to make a mat to go under Malcolm’s sleeping bag when he’s camping. He said that something like that would made a really nice rug for his new tree house (hint, hint).

Trapdoor leads to roof

Malcolm was already talking about how it would be nice to have a trapdoor in the floor, too, “just in case.” It’s a gender-neutral tree house. Neighbor Will’s two daughters and Malcolm are joined at the hip every waking moment, so there is no immediate prospect of a No Girls Allowed sign going up.

Photo gallery of tree house pictures

I was no fool: I showed up after all the heavy setup work had been done, and I left when it looked like a thunderboomer was going to roll in. The rain never materialized, but it was close enough that temps dropped to a comfortable level and Matt and Neighbor Will pushed to get the roof on before knocking off for the evening. So, you get to see the middle part of the project.You’ll have to click on Matt’s video to see the whole deal.

SEMO’s Cardiac Hill

Several of my readers have mentioned Cardiac Hill on the Southeast Missouri State University campus. They’re mostly crazy folks like Terry Hopkins, who participated in track, a sport where you run even if nobody’s chasing you.

It’s quite a bucolic sight, looking off to the west of the path that leads from the Academic Hall area down to The Towers and other student housing. Even on an afternoon when the temperatures are sliding to around 103, the shade and greenery have a cooling effect. You can click on the photos to make them larger.

Cardiac Hill’s not so tough

In 1990, we took the Great Trip Out West, which included the Grand Canyon. I knew that you should never walk DOWN further than you are able to walk up, so I discouraged Wife Lila and Sons Matt and Adam from going down too far on a day when the temperatures came close to the surface of the sun as measured from Mercury.

When it came time to turn around (actually, when it was PAST time to turn around), I got about 15 steps and found myself with my hands on my knees, bent over, watching sweat splash onto my Redwing boots. Adam, who was about 10, kept scampering around us wanting to keep going. Finally, hoping he would get lost or eaten by a goat, we turned him loose.

When we looked up, we saw him seemingly half a mile ahead of us hanging over a lookout point with some concerned-looking adults. We could make out that they were having a serious discussion, probably about his welfare. Finally, he leaned way out and pointed to us. He was probably telling the strangers, “Those are my parents, if they live.”

Learning from the Grand Canyon

Even though it didn’t look like Cardiac Hill was all THAT steep and it wasn’t all THAT long, I used the Grand Canyon Rule and went down only about a third of the way, not quite to the emergency stanchion that I assume is the half-way point.

I DID mention that it was 103 in the shade, right?

I’m going to use a different rule next time: Take the temperature (103), subtract my age (65) and subtract the grade (12.5 degrees, estimated). The result (103-65-12.5) = 25.5 feet, the distance that I should consider walking down Cardiac Hill. I was going to build in humidity, but that would have left me with a negative number to walk.

Thanks to Dr. Bambi, AKA the Yarn Bomber, who told me how to get to Cardiac Hill.
