Hey everyone -- I have settled upon Bitcasa as my solution. I liked it so much I threw down for an annual membership already. While I have had some major issues in the last month with their software on Mac OS X, they have been very responsive to my requests and have updated their software regularly and now it is pretty solid. I have mirrored my desktop, documents, music, and movies from my MBP, and I also have been able to sync my local USB drive and my Drobo to the cloud all through rsync -- because Bitcasa basically provides a mounted file volume that you can interact with as any other volume. So I basically use mirroring for my laptop and then rsync my Drobo to the cloud.
PROS:
- Fair price especially at the annual level of membership
- Mounts your cloud drive as a logical volume on your Mac, so you can use rsync to mirror USB drives and interact with the files as if they were local. Bitcasa handles most of this through an abstracted file cache.
- Software works well (now) for Mac, and there is an iOS app.
- Web interface is pretty slick.
- Encrypted, fairly easy to share.
CONS:
- Bitcasa software is definitely undergoing growing pains. Often times I will have to relogin to the app on both Mac and iPhone after reboot.
- The Mac finder software itself has been pretty rough until the last week or so, but they have been fairly quick to respond to my requests and push out updates.
- The iPhone app doesn't upload images in the background, so if you switch apps you won't continue to upload photos. I have 4,000 photos in my camera roll so this takes a very long time and my phone locks screen after 5 minutes of inactivity due to corporate security, so I still have yet to upload all of my photos.
However despite the growing pains, I am happy with Bitcasa. I think if you give these guys another few months they will continue to build out an impressive cloud backup platform. I am excited to return to the US to a high-speed connection where I can finally and safely backup the 4TB my Drobo stores right now to the cloud so I don't have to continue backing up my drobo to yet another USB backup device. Going forward, I can stick with the Drobo and rsync it to the cloud. Furthermore, I can access that content anywhere which is really exciting for me. It would be amazing if I could stream movies directly via Bitcasa, which I think they are aiming for, but thus far it doesn't seem to work well for me.
Going back to the original thread, though, I can sync my MBP and other devices to Bitcasa, and I can also rsync my USB drives up to the cloud without requiring local mirroring of those files.
