Thumbs-Up: AncestryDNA Improves Genetic Matching Technology

ancestrydna matches improvedDouble good news: AncestryDNA has made some improvements to the way they calculate your genetic matches, but they haven’t messed with the site format or layout. There is one downside–so keep reading.

Change is afoot at AncestryDNA. Again.

While stability and predictability seem like honorable qualities in a company or product, when it comes to tech tools, in the ears of tech companies, those words sound more like dated and old. Of course, we are used to this by now. I had a client tell me recently that he wanted to be in touch sooner, but his grandson “upgraded” his computer to Windows 10 and then promptly left for college the next day, leaving him fighting with a new interface and operating system.

The good news is, you won’t have this problem with Ancestry’s new update. There aren’t any changes to the interface or the layout of the information. In fact, many of you will not even notice at first that your match list has changed. You’ll just see this notification when you log in:

But in fact, there likely have been some adjustments made to your match results:

  • Some of your third cousins have been demoted to fourth cousins.
  • Some of your fourth cousins have been demoted to 5th-8th cousins.
  • Some of your Distant Cousins have disappeared off your match list
  • You have new cousins on your Distant Cousin match list.

In general, from what Ancestry has showed us, you gain more than you lose.

Changes in the dregs of your match list may not seem like that big of a deal. But Ancestry has made some big changes in the way that they are calculating matches. They are getting better at it. Which means you match list is now more representative of your ancestral connections, even at the very distant level.

There are two big pieces to this matching puzzle that Ancestry has tinkered with in this latest update: phasing and matching.

You will remember our discussion on DNA phasing and how it can impact your matching. Ancestry has developed a robust reference database of phased DNA in order to better phase our samples. Basically, they have looked through their database at parent-child duos and trios and noted that certain strings of DNA values often travel together. It’s like they have noticed that our DNA says “A black cat scared the mouse” instead of  “The brown cat ate the mouse” and they can then recognize that phrase in our DNA, which in turn helps our DNA tell the true story of our heritage.

In addition to updating the phasing, Ancestry has revamped their matching method. In the past they viewed our DNA in small windows of information, and then stitched those windows together to try to get a better picture of what our DNA looked like. Now instead they have turned to a point-by-point analysis of our DNA. Again to use a sentence example, with the window analysis we may have the following sentence windows:

ack and J

ill went t

he hill t

etch a pai

l of water.

AncestryDNA match comparisonOf those windows, you may share the “etch a pai” with another individual in the database, earning that cousin a spot on your match page. However, the truth is, that bit could say “sketch a painting” or “stretch a painful leg” or “fetch a pail.” With Ancestry’s new method, they are able to see farther on either side of the matching segment, making this clearly “fetch a pail.” That means better matching, which means more confidence in your cousin matches.

The downside to this update is going to come in the reorganization of some of your relationships. Ancestry has tightened their genetic definition of your third and fourth cousins. Basically, that means that some of your true 3rd cousins are going to show up as 4th cousins, and some of your true 4th cousins are going to be shifted down into the abyss of 5th-8th cousins.

This brings us to the downside of this AncestryDNA update: changes to the Shared Matches tool. The shared matches tool allows you to gather matches in the database that are related to you and one other person, provided you are all related at the 4th cousin level or higher. This tightening of the belt on 4th cousins means that some of them are going to drop through the cracks of that tool, really limiting its ability. Grr. Hopefully, Ancestry will fix that, and expand this tool to include all of your matches. They have their fairly good reasons for this, but still….

So, as the winds of change blow yet another iteration of the AncestryDNA match page, I think we can see this as an overall win for doing genealogy with our genetics at Ancestry.

Backing Up Your Genealogy with Backblaze – Q & A

Backing up your genealogy with Backblaze is a critical move if you want to protect your family history. Let us answer your questions and share with you how the cloud backup service Backblaze can be the answer to effectively backing up and protecting all your genealogy data.

backing up your genealogy with Backblaze

Recently, we received some great questions concerning the cloud-based computer backup service, Backblaze, one of our trusted sponsors of The Genealogy Gems Podcast. The answers to these questions will give you with the confidence to put a reliable cloud backup plan in place so that your family history remains safe and secure.

What is Backblaze?

Backblaze is an online back-up tool that stores copies of your computer files, and allows you to restore them in case your computer is lost, stolen, or destroyed. It offers unlimited storage and supports every type of file, including large video files and genealogy tree files.

Once installed, Backblaze works 24/7 through your internet connection to save every change you make. Backblaze also keeps your files safe offsite (at their data centers) with 24-hour staff, biometric security, and redundant power.

Unlike Evernote or Dropbox which are designed to allow you to work with your files across multiple devices, Backblaze is “set it and forget it” protection should the worst happen.

While you can sign-in and access your files from multiple devices, it’s primary purpose is to provide a back-up plan so you can restore your data if something happens to your computer. While external hard drives are great for when your computer crashes, they can’t help you if they are destroyed in a fire or flood along with your computer because they were both in the same location. Off-site backup and multiple copies (redundancy) are key when it comes to protecting your precious genealogy research.

Answers to Your Questions about Using Backblaze for Cloud Storage

Q: I am excited to begin using Backblaze for the first time! However, I am a bit uncertain of how to actually begin. Can you walk me through it?
A: Lots of our readers are a little uncertain when it comes to using something new. We have created a blog post titled “How to Download Backblaze in 4 Easy Steps” that will walk you through it!

Q: I have a number of computers at home and I also have a network drive. What does Backblaze cover? Will it back up everything?
A: No, and here are the details. You can have multiple computers backed up on your account, but each computer will require its own subscription (about $6/month). Backblaze can back up all file types and storage is unlimited, so large files from your hard drive are not a problem. It also backs up every time you make a change to a file and your backup will always have the most current version. You can view and restore your backed up files at any time via download, USB flash drive (mailed to you,) or USB hard drive (mailed to you.) Backblaze does not however support the backup of network drives.

Q: Does Backblaze also save earlier versions of my files like Dropbox does?
A: Yes. You can locate earlier versions of files or even files that have since been deleted. To learn how to do this, follow the step-by-step directions in this article from Backblaze.

Q: I live in a fairly remote location, and have a limited Internet data plan. Will Backblaze use a lot of data?
A: Backblaze, as with any Cloud backup service, does require a strong internet connection and could take days or weeks to completely back up your entire computer. This will depend quite a bit on how much data you have on your computer. If you have a limited data plan or slow internet, you could experience delays or what appears to be high data usage while the initial backup is occurring. Here is a link to a helpful page on the Backblaze website called “Bandwidth Speed Test to Backblaze”where you can test your internet speed. Backblaze is designed not to “throttle” or slow down the flow of uploads. It strives to use your full internet bandwidth. However, you do have the option to set it to slow down the backups. The “Bandwidth Speed Test to Backblaze” page provides instructions on how to  throttle your download speed so that it doesn’t use up as much bandwidth.  While this will cause your initial backup to take longer, it can clear help ease  up on the data usage and allow for your other internet activity. You can also pause backups, or set them to start manually or at scheduled intervals. Once your initial backup is complete, the data usage should slow down.

Q: Because Backblaze backs up my computer automatically and instantly, what happens if I get a virus. Will that also be transferred to Backblaze?
A: From Backblaze blog
“Since Backblaze is…continuously running online backup solution and is not locally connected to your machine, all of your backed up files would be available for restore with minimal or no data loss (depending on the last backup time before the machine was infected).”

A Note from Lisa About Backblaze and Genealogy

Lisa answers your questions“You’ve heard me talk about Backblaze on the podcast, and why it’s my first choice when it comes to backing up my precious genealogy research and personal files. I met their CEO Gleb Budman at Rootstech and after lots of research, I decided that Backblaze was the best cloud backup service out there! Maybe you’re still on the fence about it or maybe you’ve been putting it off, unsure of how complicated it is to set up or if it’s really worth the cost. So I got in touch with our friends over at Backblaze and we’ve set up a special offer for those of you have not yet begun protecting your data.”

Help! My Email Doesn’t Fit in Viewer Window

screen resolution settingRecently I heard from Carol in St. Louis, Missouri, who was frustrated that she couldn’t read my entire email newsletter. “Would love to know what you are saying,” she says. But my newsletter email doesn’t fit in her email window. “I don’t want to toggle to the right to see the end of each line and then have to toggle back.”

The good news I shared with Carol is that she could fix this problem–and so can anyone else who has trouble with emails not fitting in their viewers.

Email sizing is related to your computer’s screen resolution setting, and a variety of other variables. It’s different for everyone. 98% of our readers see the email perfectly fitted to their screen.

As you can see in the screen shot here, the email Carol forwarded me appears neatly and completely in my email window in my browser. (I’m on a PC using Firefox.) In cases where it doesn’t come through to your email account that way, we provide a link at the top of the email that you can simply click to view the email on a new web browser tab fitted to the page.
