Strongspace is a safe place to gather, store, back up, and share any type of file. You can upload and download files via SFTP (Secure File Transfer Protocol), HTTPS (Web browser access over Secure Socket Layers) and even RSYNC over SSH (a rapid, low bandwidth way to "sync"). Strongspace is designed so that everything happens over a secure, encrypted connection. Your password and other sensitive information is encrypted with Blowfish, and files are moved to-and-from servers to your computer over encrypted channels at all times.
Strongspace is pretty easy to use and set up. We use strongspace as a back-end to Basecamp which is a project management website. Inexpensive when compared to other online storage options. No special software needed to upload & download files.
Recent connection issues have led to multiple system outages, constantly unable to access files or upload new files due to what Strongspace has deemed "portal issues".
No live customer service number to call, all support is done via e-mail. Responces are never fast leaving me to believe that our urgency is their "we'll get on it sooner or later." They should have a number to call for urgent issues, even if it means potentially paying for the service call, having a live person to talk to is more comforting that an issue is being taken seriously. They don't even offer online chat support.
