Lately, Backblaze has been seeing a few reports stating that a very specific type of ransomware, known as CryptoLocker, that takes control of a victim’s computer and holds it hostage until that victim pays to get it removed. It is known as ransomware because if Cryptolocker is not paid within a specific timeframe, it will destroy the key that is needed to unlock your computer’s data, making the data and files on your computer and any attached external or backup drives permanently inaccessible.
Backblaze is Not Anti-Virus
Some Backblaze users have been writing in to ask us if Backblaze protects them against their data being held hostage by such programs. The answer is, yes.
While Backblaze is not anti-virus or anti-malware software, in this particular case Backblaze would be useful in ensuring that the data is retrievable. How does that work and what makes Backblaze different than an attached local backup? In cases like these, where the ransomware or malware takes control of and encrypts all the data on the user’s computer and external drives, the data is essentially locked with a very strong encryption key. The only way to unlock the data is to either break the encryption, or pay to have the key sent to you so that you can once again access your data.

How Backblaze Can Help
Since Backblaze is an unlimited, and 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).
What this means is that if you are a victim of ransomare like Cryptolocker, you could order a Backblaze restore from a date before your machine got infected, and then have your computer reset back to its factory settings, essentially removing everything, including the ransomware from it. You would need to reinstall all of your programs, including Backblaze, but the data that was on your computer before the infection, including your: photos, videos, movies, music, and work document, could all be safely restored.
