Tips & Words
Thanks to everyone who submitted Tips and Words as mentioned in last weeks newsletter. (If you haven’t gotten around to it, keep on sending ’em — the details are in last weeks newsletter.) It’s been exceptionally helpful, and allowed me to get ahead a little. Why get ahead? Well….
Busy Summer? Nah. Busy Fall!
My summer’s been pretty peaceful, but these first few months of fall have a number of things all happening at once that will keep me pretty busy. A multi-day ham radio volunteering gig, out of town guests (twice!), a cross country trip (hello St. Louis!), and a camping trip are all on tap. For most I expect to remain connected, but I’ll definitely have some other things competing for my attention.All that is to say that the Ask Leo! side of my life might see a slowdown on occasion.
One of the comments I quickly received on my article “Using OneDrive for Nearly Continuous Backup” was this:
In other words, if you’re using OneDrive (or Dropbox, or other similar services) to automatically back up files online whenever they change, doesn’t that mean that ransomware would cause those backups to automatically be replaced with their encrypted versions?
But before you give in to a knee-jerk reaction to avoid online backups completely, consider this: they’ll give you more options, not fewer, should ransomware ever strike. In fact, they could save you in ways other backups might not.
Online backup to the rescue
Yes, OneDrive has a Recycle Bin. This means OneDrive can save your data from ransomware.
It would work like this:
OneDrive just saved your bacon. What’s more, everything I’ve described above all happens without any other form of backup in place.
But of course, you also have other forms of backup — right?
Belt and suspenders and suspenders
The person who originally left the comment continued:
A simple, but probably inefficient, means I use is to weekly make a copy within OneDrive of backed up files.
This is (almost) exactly what I do myself. Every night I make a copy, elsewhere on my machine, of everything in my OneDrive folder, in the form of a compressed archive (like a “.zip” file). Should I ever succumb to ransomware, I can recover my files from that additional backup. I would not make the copy “within OneDrive”, however, since ransomware could impact that backup copy as well.
Of course, on top of that, I have my nightly backups running to an external hard drive: monthly full backups with daily incrementals, meaning I can always recover the files “as of” a few days ago. (And in case I happen to run across ransomware that also tries to encrypt backups … some of those backups are copied elsewhere, effectively “offline” and not directly accessible to my machine.)
It would take a lot for even the nastiest ransomware to cause me to lose any significant number of files.
You don’t need to go overboard
You don’t need to be as backup-crazy as I am. You can protect yourself with just a few simple steps.
- Use OneDrive for nearly continuous backup of your day-to-day working files.
- Enable File History. File History, though sometimes disabled by more aggressive ransomware, will also let you restore a file to the condition it was in prior to encryption, and can protect files outside of those you keep within OneDrive.
- Take periodic full, and more frequent incremental, image backups of your entire system to protect from almost any type of failure.
- Every so often, take one of those full backup images and copy it to offline storage.
And, honestly, that last one is just to make people panicking about ransomware encrypting their backups happy. That doesn’t happen so often that I consider it truly critical, particularly with what we’ve just discussed about OneDrive’s Recycle Bin.
Don’t let the worst case scare you away from reasonable choices
What concerns me most are folks who say they won’t use online backups because their files might be encrypted by ransomware and the online backup would be useless.
Ransomware is only one type of threat. More importantly, it’s not even the most likely threat.
For example, a hard disk failure can be much more destructive than ransomware, and is probably much more likely to happen. Even more bluntly: you’re more likely to accidentally overwrite or delete a file than you are to personally encounter ransomware.
Even if the Recycle Bin didn’t exist, continuous online backups save your files from many threats that don’t involve invalidating the backup.
The same is true for nightly backups to an always-connected external hard drive. Yes, there’s a chance that ransomware could encrypt your backups. There’s a higher probability that you’ll be glad you had those backups current for a variety of other failures.
Making backups easy, timely, and automatic is more important than fearing one specific — albeit destructive — form of malware.

Full, incremental, and differential: three confusing terms when it comes to traditional backups.
In this article, I’m going to describe how each one works so we can compare them and see which is most appropriate for you.
