I like and recommend Backblaze

You will sleep so much better knowing that you have Backblaze. I can't imagine how you get more for your money for $5.

I've used other online backups, Backblaze is my favorite.

I'd like to thank you very much for taking such good care of my data.

I just had my socks knocked off by @backblaze customer service, and you know it takes a lot for me to say that. Loyal customer for life now.

I was so thankful I had backblaze after my apartment was recently broken into and a drive holding all my photos from a recent international photography trip was stolen. The entire purpose of my $5k whirwind trip was to take photos and I would have been heartbroken if it had all been for naught.

It wasn't until the next morning that I realized Backblaze would probably have my deleted files. So I logged into my Backblaze account and navigated to ~/Library/Mobile Documents/, and sure enough, every last one of my deleted files were sitting right there, waiting for me! What a relief.
