It will work with just about any cloud provider that you might need, including Backblaze B2. It's incredibly flexible in terms of configuration and storage options. Pros: I'm focusing this review on the Server Backup edition of CB backup.
So, in conclusion, I would certainly recommend the software as such thing that helped me and resolved my issues. It's important for me as I have a lot of data to be backed up and can't afford spending much time for it, though need rely on it's outcome. It seems due to multithreading engine it can retain very high speed of upload, in fact as high as I hardly ever had while being used other upload methods. Especially I was happy enough about the speed and stability of bandwidth wile backing up.
Hopefully, eventually I ran across MSP360 software and surprisingly had a delightful experience with it right away. However, in most software solution I've been testing I was rarely satisfied, whether it's been the lack of usability, and mostly about the amount of the software maintain the speed of connection and the bandwidth while backing up. As a photographer I have to manage huge amount of image files with RAW data, these are quite bulky and ravenous in term of HDD space used, nevertheless quite important for me to save and have a backup of it. Overall: I spent a plenty of time comparing a lot of software, trying trial and free versions, looking for a solution that'd help me complete my home/small business/hobbyist backup.
