How to almost sync with BitCasa mirrors

BitCasa is a free cloud backup tool, which has a basic mirroring function for files that you want to be automatically backed up into the cloud instead of scheduling a backup. I was looking for a replacement for SugarSync’s folder synchronisation feature, and BitCasa’s functions are close but not really there yet. It seems that they have a beta app which is based upon bittorrent, but again not for a live sync.

Aside – the BitCasa cloud solution is pretty neat. I’m impressed by what they offer and their price point. The paradigm that it uses is not an attached storage volume really, but more like an external drive which happens to be on a remote server. That drive is almost read-only to your machine, and certainly read only from any other machine that tries to access the files. It is cloud backup, not a sync service.

This is the scenario:

Initial setup was a folder on my laptop and desktop were set to always be kept in sync. This meant that files were always kept in reasonable sync, and I didn’t have to worry about manual copying or a scheduled copy which I might forget.

Now what I have is a folder on each location which are both copied up into BitCasa’s servers (yes, up into that fluffy white cloud of absolute trust). The difference is that each machine is used for slightly different things, so that what I do on the laptop generally isn’t used on the desktop. The sync is for emergencies, so it might work.

The trouble is that each machine uploads the selected mirrored folder into a separate space in that cloud, and the two areas are never sync’ed together. I’d love them to, but for the purposes of having my files backed up somewhere, this is enough.

When it comes to wanting to use one of the files which is on the other machine’s backup it needs to be copied back down to the new machine and stored. Just like an offsite solution, you don’t go editing the back-up tape. Now that I get the mindset, I don’t mind so much. If something exceptional happens in the file-sync space I’ll probably post it here, but till then BitCasa will get a bit of playing around.

Happy backups.
