OK, so I'm not a big fan of the NSA and Spideroak has been suggested over Dropbox. Did some research and one of the really big flags for me is that Condi Rice is on Dropbox's board. It also seems that Dropbox's privacy guidelines are a joke. So…I tried a encrypted DMG file the other day. That didn't go over well because Dropbox wants to sync when it detects changes in the DMG. But if you have the DMG open it can't and so you end up redownloading the entire dang thing again which is obviously not what you want. So, I went to SpiderOak. Now, it's my understanding that they no longer support PowerPC, but like most stuff in our little world we can use previous versions. The latest version of SO on Intel Macs uses the SpiderOak Hive. It auto creates a folder in your Users folder called that and just like with Dropbox anything you drop in there syncs. It's all automatic. But apparently it did not used to be. Here's where we get into syncing with the Intel Mac at work. You can still do this, I am doing it right now. But you need version 4.8.4 of SpiderOak for Leopard/PowerPC Macs. It does not have this Hive function, but you can create a decent work around. I am ignoring this Hive folder on the work Intel Mac. I created a SpiderOak folder in my Users folder on the Intel Mac and my PowerPC Mac. I then created a sync profile setting that syncs both folders. You have to connect your devices first so that SpiderOak sees both folders. I didn't do that and it took me a while to work this out. Also, on 4.8.4 on the PowerPC Mac you need to have that folder as a saved backup first before you can create a sync profile. You'll need to do this for each computer device you want synced. Although you should just be able to edit the sync profile to include the new folder on the new device. SpiderOak also has an iOS app. It's unnecessary to sync that device (I don't think you can) as it can automatically see what's on all the other registered devices. It's working for me and since SpiderOak, unlike Dropbox, knows nothing about your files I'm good. The only downside for me is that I have far less storage on SpiderOak then I do Dropbox and there is also no direct way like in Dropbox to open the synced folder. My intent is to leave only generic stuff on Dropbox. A word about Sugarsync and Box. Box is great! I have 50GB, but there's no way you can get it to work with a PowerPC Mac. Consequently, I have to use a browser for it. Sugarsync is also great and there is still a PowerPC version of their app that works, but their problem is that you cannot upload any file of 300mb or more. So, there you go. If anyone wants version 4.8.4 of SpiderOak, let me know. I found it and am using it. EDIT: After looking through the settings on the Intel Mac version it appears you can disable the SpiderOak Hive sync. I've done that, which leaves me with the sync I set up on the PowerPC Mac.
