Only useful in some cases Pros: very fast, doesn't hog CPU or memory like CrashPlan Cons: deleted files are only retained for 30 days. Backblaze is essentially only useful in cases where a hard drive completely fails / external hard drive is physically broken. If a hard drive starts slowly corrupting over time, or if you accidentally delete files and don't realize it within the 30 day limit, you're screwed. Absolutely useless in those cases.

Woeful product and even worse customer service. AVOID!! The one time I needed to use the download function, their software does not work and then the backup was missing lot of important files from months earlier even though it was on continuous backup. Their customer service is a joke. Do yourself a favour and avoid at all costs

Good service, but canceling is ridiculously difficult 4star because their customer support pulled through. I kept subscribing for months after my computer died, because the process for canceling was way harder than it should be. I finally got my act together and asked for backup of my data on a $204 1TB drive. I had some issues recovering data that if unresolved, which would have resulted in a 1star review, but within 1 day their support gave me a workable solution and I am satisfied. The process for canceling service is ridiculously tough, and I checked through 3-4 different options and it seemed to work, but I don’t know if I checked too many or not enough. Regardless, it worked out, and if I needed an automatic backup in the future, I wouldn’t hesitate to consider Backblaze.

What an awful service What an awful service. Their backup client is terrible, expensive, and so slow it's worthless. I regret signing up with this useless service.

It sucks It sucks! massive price increases and all kinds of sleazy tacktings to prevent you from cancelling the renewal.
