Choosing an Online Backup Service - Revisited

[Update 3: After tweeting Backblaze about me not being able to use their service because of no Mac support -- I get a reply inviting me to their private beta. Thanks Backblaze! But now my decision is that much harder :-)]

[Update 2: I just realized that Backblaze does not currently have a publicly available Mac version. That rules them out, for now]

[Update: I have received two more candidate possibilities from Twitter of all places. ScottBourne of Mac fame recommended BackJack which looks interesting, but maybe a bit overkill for me. SpiderOak_Inc must have seen my posts and recommended SpiderOak, and, while I was wary and had never heard of them, their service is quite compelling, especially the zero knowledge policy. And here I thought I had almost made my decision].

Back in December, I wrote about my desire to choose an online backup service. Since then, I am still without a true service (I am doing some hodgepodge things right now to give me some semblance of offsite backup; but nothing very formal).

The desire to choose one is still there; and for whatever reason, I really wanting to choose one like right now.

I have narrowed my choices down to 4:

  • Carbonite (they finally have a Mac client; plus I can support Leo Laporte and TWiT since Carbonite sponsors Leo's awesome and free podcasts)
  • Backblaze (they are less known, but get great reviews; plus their front page "ad" is kinda cool :-) ---- Mac version currently closed to public, but I have beta invite)
  • SafeCopy (I believe they are quite new, but people have given them thumbs up; but are they too new??)
  • DropBox (There free service is actually quite compelling; I use it....but I think they are the costliest of the bunch here when it comes to getting more storage)

[Mozy -- you are out because you still cannot handle encrypted files from what I understand -- prove me wrong!]

Let me give you my current thought process:

Use the free version of DropBox to share files between my Windows laptop and my MacBook Pro, and then use Carbonite to backup offsite. I would need DropBox because Carbonite and many others only allow you to register one computer for backup, so I would use DropBox to move files I want backed up from my Windows computer over to the Mac (which will be my primary, registered computer). But, something like a SafeCopy would allow me to have unlimited computers registered because their pricing is based on storage.

So help me out. I would appreciate it. I would especially appreciate any representatives from the above companies coming by and selling me on their service.

Thanks!
