Pros

Pros

“One of the best parts of Backblaze is their pricing is based on actual usage, so you're not paying for space you're not using.”
TL

Tiffany L.

Owner

“One of the options they include is the choice to purchase a hard drive loaded with your data for a full restore, or you can use the file explorer to download individual files through your browser.”
NW

Niko W.

CEO

“The backup software automatically backs up any of the hard drives or files you request. If your computer goes offline for a particular length of time, you will receive an email reminder that the utility cannot connect to your source.”

Cons

“It does not back up exe files which are mainly software installation files but that is also where malware likes to hide.”
