I use Backblaze as my backup solution and actually really like it. Today, I only have my ipad with me and forgot a file (audio file, 80mb) on my Mac at home. I thought, alright no problem, I have Backblaze, I can simply download it… navigated to the folder, clicked download and… got an error message: “File too large! Please select a file 30mb or less”… this astonishes me - in a bad way. Is this expected behaviour? An ipad-exclusive problem?
For next time, if you use an Airport or Internet router that supports UPnP or NAT-PMP, and you let your firewall allow remote connections, configure Apple’s Back To My Mac, and get file sharing, screen sharing and remote login.
If you want to access files from any device anywhere another option is Parallels Access, which costs $20/year. The nice thing about Access is that you can log into your Mac from a web interface, so you’d be able to grab that mp3 file even if you were on Linux, Windows or a Chromebook.
